Technical Information Magazine 202305-01 Evaluation of SiO2 Films Using Mercury Probes

The electrical properties and film quality of the SiO2 film on the Si substrate were investigated in detail for each deposition method.

The technical information magazine The TRC News provides the latest information on analytical techniques useful for research and development, solving production troubles, and quality control. **Abstract** Using mercury probes (Hg-Probe) and various physical analysis methods, we investigated in detail the relationship between the electrical properties and film quality of SiO2 films deposited on Si substrates using different methods. Compared to thermally oxidized SiO2 films, SiO2 films deposited by chemical vapor deposition (CVD) were found to have higher moisture and hydroxyl group content, and lower order in the SiO2 network structure, as revealed by RBS, XPS, FT-IR, and SIMS. C-V measurement results using Hg-Probe showed that SiO2 films deposited by plasma CVD have a high positive charge density, while those deposited by ozone CVD exhibit a high density of mobile charges, and it was confirmed that there is a correlation between moisture content and relative permittivity. I-V measurements also indicated that the leakage current of SiO2 films deposited by ozone CVD, which have high moisture content, is significant. Additionally, C-V measurements combined with wet etching confirmed that SiO2 films deposited by plasma CVD have a spread in charge distribution near the interface. **Table of Contents** 1. Introduction 2. Experiment 3. Results and Discussion 4. Conclusion

Quality assessment of walking based on human and lifestyle engineering (wearable clothing)

What does a high-quality walking style look like? I will also introduce methods for evaluating how walking style changes with clothing.

**High-Quality Walking** It is said that "metabolism-boosting walking" can transform your body into one that easily burns body fat. To achieve this, a high-quality walking style is required. Specifically, it is important to primarily keep your back straight and to widen your stride. For more details, please refer to the attached materials. **Methods to Achieve High-Quality Walking and Its Effects** - **Thigh Stimulation** For example, a method of stimulating the thighs through clothing can be considered. - **Widening the Stride and Increasing Muscle Load** By stimulating the thighs, they are lifted higher, the knees extend, and the stride naturally becomes larger. At this time, the load on the quadriceps and calf muscles, which are used when pushing off the ground, increases, resulting in the use of the entire thigh muscle. - **Increased Energy Consumption and Changes in Body Silhouette** With a larger stride, energy consumption increases significantly, and the entire body becomes more toned. This leads to changes in body shape, such as a flatter abdomen and lifted hips. **Expected Effects from Innovating Clothing** By lifting the hips from below and pulling the back and abdomen against each other, while pushing the waist and abdomen, it is expected that a beautiful posture and body shape can be achieved.

Evaluation of flow-accelerated corrosion (FAC) in the elbow section of operating piping.

Detecting FAC that had not been detected before at the elbow section of the piping in use, without removing insulation or cladding materials.

Depending on the equipment, high-temperature and high-speed fluids flow towards the 90° bend of carbon steel piping. As a result, it is inevitable that flow-accelerated corrosion (FAC) will occur on the outside of the elbow within the piping. A major petrochemical refining company in Asia has requested Eddyfi Technologies to develop an inspection solution capable of detecting FAC and erosion at the elbow sections of carbon steel piping where high-speed and high-temperature fluids flow. *For more detailed information, please refer to the PDF document. Feel free to contact us for further inquiries.

Reviews and Feedback from Food Manufacturers

[Case Study] Solving Noise and Dehydration Issues in Food Manufacturing Lines All at Once with Hayate!

■Introducing Company: A certain food manufacturing company The previously used blower-type dewatering device had unsatisfactory dewatering performance, and the working environment was in a harsh situation with high noise levels of 95 to 100 dB. Workers were regularly troubled by the high noise, leading to issues such as work stress and decreased concentration. ■Effects revealed by a 2-week rental verification After a 2-week trial of the air nozzle "Hayate," the following effects were confirmed: 1: Dewatering performance significantly improved, drastically reducing defective labels and NG products in image inspections. 2: Noise levels were reduced by approximately 15 dB(A) or more, eliminating the need for earplugs and greatly improving the working environment. 3: Contributed to significant reductions in CO₂ emissions, disposal costs, and power consumption. ■Unexpected "good troubles" after implementation? 1: After the introduction of Hayate, the operation was so quiet and comfortable that workers mistakenly thought "the dewatering device is not operating," leading to a temporary line halt. 2: An executive from outside the factory entered for an inspection, wondering, "Is the line stopped?" There were even pleasant trouble cases where people were surprised by how quiet it was. This is indeed proof of satisfaction with both the dewatering effect and noise reduction effect.

Reviews and Feedback from Manufacturers of Retort Pouch Food Products

The water droplet removal effect was far superior to that of the air nozzle previously used.

"The water droplet removal effect was far superior compared to the nozzles we had been using previously." We received such feedback from a manufacturer of retort pouch food products who actually implemented it. - The performance of blowing away water droplets is overwhelmingly high, significantly improving the efficiency of the drying process. - Since the air is concentrated and directed at the target, we were able to reduce the flow rate. - The load on the compressor has been greatly reduced, leading to expected energy-saving effects. - The wind noise is very quiet, contributing to an improved working environment. - Made of SUS, it is resistant to corrosion and has excellent durability. - The foreign objects blown away are less likely to scatter around, which is advantageous from a hygiene management perspective. - The nozzle is of very high quality, and I truly believe it was a good decision to implement it. The air nozzle "Hayate" demonstrates performance that sets it apart from the nozzles previously used in water droplet removal, foreign object removal, and drying processes on food production lines. In particular, its highly directional high-speed laminar airflow simultaneously achieves "efficiency" and "energy savings," which were difficult to realize with conventional methods.

【Reviews】Evaluation from a beverage manufacturing line setup manufacturer.

Low cost is the top priority" - Even though I thought I didn't have that mindset, I realized that I had been relying on "the usual selection.

A device manufacturer delivered a device incorporating conventional air nozzles to an end user. However, the dewatering performance was not as expected, leading to ongoing adjustments. Despite repeated trials, including adding nozzles, there was no improvement in the rejection of defective products during the inspection process. During this time, the person in charge encountered the air nozzle "Hayate" at a trade show. Later, when they validated it using a demo unit on the actual device, they found that it could effectively remove even the fine water droplets that had previously been difficult to eliminate. Moreover, while four conventional units were insufficient, just two Hayate units provided sufficient effectiveness. This became the decisive factor for adoption. The introduction not only improved dewatering performance but also led to the following benefits: - Contribution to energy savings for the end user - Reduction in complaint handling and management tasks - Maintenance of trust relationships - Reduction of "hidden costs" such as labor and travel expenses There were also positive impacts on stable operation of the production line and reductions in waste and CO₂ emissions. While controlling costs is important, this experience prompted a reconsideration of "what truly constitutes a valuable choice," as reflected in the feedback received.

【Reviews】Feedback from circuit board manufacturing companies.

I am experiencing the benefits of implementation in terms of particle countermeasures, energy-saving performance, and quietness.

We have fully introduced the Hayate series into the dust removal process of our substrate manufacturing line. The air nozzles we were previously using had a dust removal rate of about 50%, which had plateaued, leading to ongoing quality issues due to residual and reattached foreign substances. When we first tested the Hayate, the first thing we noticed was the difference in the quality of the airflow itself. Unlike the air nozzles we had been using, the Hayate provides a stable supply of thin, directional air, ensuring that the airflow reaches the target surface consistently. It was clear from the results that it effectively blows away foreign substances. Upon inspecting the foreign substance retention rate, most models achieved a dust removal rate of over 70%. In some models, a dust removal performance of over 99% was confirmed, significantly improving product quality and, as a result, greatly reducing the number of defects caused by foreign substances. Furthermore, air consumption has been reduced by more than 50% compared to previous models, and noise levels have also been noticeably lowered. This has reduced stress for operators and contributed to improving the working environment within the factory. Currently, we have adopted the Hayate as the standard specification for our dust removal process, and we are experiencing benefits in terms of quality, environment, and cost.

[Reviews] Feedback from a high-value-added fiber material manufacturer.

"An uninterrupted site creates the highest quality." ~ The amazing stable operation brought by zero chocolate stops ~

"Honestly, I underestimated it. But now I can't let it go." In the manufacturing process dealing with thread-like fibers, image inspection is essential to prevent the outflow of NG products to the next process. However, the attachment of lint to the lenses and reflectors was serious, leading to unstable inspection accuracy, and it became routine to stop the equipment every two hours for manual cleaning. We tried various air nozzles, but the honest feedback from the field was, "No matter which nozzle we use, the effect is mediocre," and "It's a waste of air and electricity, but there's no choice." At that time, a business partner introduced us to Hayate, and we conducted verification with the actual machine. The results were so effective that I thought, "What were we doing before?" The attachment to the lenses and reflectors drastically decreased, and the need for cleaning every two hours naturally disappeared. I still vividly remember exclaiming, "Honestly, I underestimated it." ■ Effects achieved by introducing Hayate Zero downtime for inspection equipment → Significant reduction in management tasks Voices from the field saying, "It has become incredibly easier" 60% reduction in power consumption and CO₂ emissions compared to before Stable inspection accuracy → Contributed to quality improvement Stabilization of production → Reduction in overtime hours Increase in daily production volume and overall efficiency improvement in the field.

【Reviews】Evaluation from a medical system setup manufacturer.

Solving the issues of scaling up small bottle dewatering devices and excessive air consumption all at once. ~Achieving both space-saving and reducing air consumption to less than 1/5 simultaneously~

Honestly, I thought further improvements were impossible. With the conventional nozzle, the dewatering effect was 70-80%, the device was over 3 meters long, and the air consumption was over 3,000 liters/min per unit. I felt a limit to the extent that I even considered design changes to extend the transport distance and promote natural drying. At that time, I discovered the air nozzle 'Hayate' on Ipros. 'I was half in doubt, but I entrusted my last hope to it and requested an experiment,' said the person in charge. When they confirmed the results in the video and experienced the actual demo, they were so surprised that they exclaimed, 'Really... is it dewatering?' The introduction effect was overwhelming. The dewatering effect reached 99%, the device length was reduced to 1/4, and air consumption was less than 1/5. Furthermore, the improvement in design flexibility and the reduction in transport distance significantly enhanced line efficiency. It also directly contributed to the reduction of CO₂ emissions and electricity costs, and it is now adopted as the standard specification. We have received feedback from end users stating, 'We will use Hayate for all dewatering areas in the future.' If you are looking for overwhelming dewatering performance with energy savings and space efficiency, please consider Hayate.

[Reviews] Feedback from automotive electronic component manufacturers.

Improving quality defects and production efficiency all at once with highly directional air - A welding fume countermeasure solution that overcomes space constraints with thin sheet and laminar flow air.

The manufacturing line I am in charge of produces small electronic components for automobiles, and since these are very important parts, it is necessary to minimize defects as close to zero as possible. As a countermeasure for fumes during laser welding, we were using an air nozzle and vacuum unit together, but due to turbulence from the air nozzle, fumes were swirling inside the equipment, leading to product defects and operational failures, which became a significant problem. Reducing air consumption to suppress turbulence was also a major challenge, as it sometimes meant that air could not reach the vacuum adequately. However, the current situation was that we had no good solutions and had to continue using the existing nozzles. Amidst this, as the equipment became smaller, the available nozzles also decreased, and we were struggling to find a solution when we discovered Hayate at an exhibition. It is a highly directional, thin-sheet air nozzle that also has energy-saving performance. When I inquired about a "super compact type," I was honestly surprised to receive a proposal for a type that is ultra-compact yet maintains a thin-sheet design and high directionality. After its introduction, my concerns were alleviated, and I was able to design the equipment without worrying about the constraints of the air nozzle. Quality defects have drastically decreased, and production efficiency has significantly increased, leaving me very satisfied.

Package testing is a method of conducting market research before the launch to determine how well the product's package design is accepted by consumers. It involves presenting several package mock-ups or actual products to the target demographic and investigating questions such as "Would you want to buy a product with this design?", "Which design would you most want to buy?", and "What kind of product image do you have from this design?" When consumers choose a product, both the contents of the product and the packaging are significant factors. No matter how high the quality or performance of the product, if the impression of the packaging is poor, consumers may not even pick it up, let alone make a purchase. Therefore, package testing becomes a crucial step that can determine success in the market. In this article, we will explain the advantages and disadvantages of package testing, key points to consider when conducting it, and research methods. *For detailed content of the column, you can view it through the related links.

Utilization of the 5-point rating scale (Likert scale) in surveys

Explanation of the rating scale method and points to note when using the Likert scale!

Have you ever seen a survey that asks about the degree of agreement using multiple choice options? The method of having respondents evaluate a specific object or phenomenon according to a pre-established clear evaluation scale is called the "rating scale method," and that evaluation scale is referred to as the "Likert scale." The Likert scale originates from an American sociologist and has now become one of the representative means of measuring respondents' opinions, perceptions, and behaviors. Since the Likert scale does not require respondents to answer with clear-cut facts, it allows for the collection of degrees or variations even for questions that are difficult to answer in black and white, enabling deeper analysis of surveys. It is also widely used in multivariate analysis. *For more detailed content of the column, you can view it through the related links. Please feel free to contact us for more information.
