High-sensitivity analysis using ICP-MS.

In the solution that dissolves the SiN film (Si3N4) on the Si wafer, there is a Si matrix derived from the film in addition to the target impurity metal elements. Therefore, accurate and highly sensitive analysis cannot be performed directly on the dissolved solution itself. Thus, after dissolving the SiN film on the Si wafer, we enabled the analysis of impurity metal elements in the SiN film without the influence of the Si matrix by applying additional treatment. An example of conducting high-sensitivity analysis using ICP-MS with commercially available Si wafers with SiN films is provided.

ICP-MS: Inductively Coupled Plasma Mass Spectrometry

The purpose of evaluating metal contamination on the surface of Si wafers using ICP-MS includes not only the contamination assessment of the Si wafers themselves but also the evaluation of contamination within semiconductor devices and the assessment of the working environment due to Si wafer exposure. Therefore, the analysis of the Si wafer surface is conducted for various purposes. ICP-MS analysis can sensitively obtain the amount of metal contamination on the surface of Si wafers, and it is also possible to specify the evaluation area according to the purpose.

We will analyze the amino acid sequence of the peptide using LC/MS/MS analysis.

When peptides are measured using LC/MS/MS, characteristic fragment ions are obtained, allowing for the analysis of the amino acid sequence that makes up the peptide. Additionally, because peptides are separated and analyzed by LC, it is possible to analyze the sequences even in samples containing multiple peptides or impurities. Here, we present a case study where low molecular weight peptides were analyzed using LC/MS/MS, and the amino acid sequences were estimated.

Thermal Desorption Gas Analysis of Ni/Au Plating (TDS)

If the plating film contains gas, it may cause defects such as peeling, blistering, and bubbles within the film. To investigate the gas contained in the plating film, TDS, which can measure the gas released by heating the sample in a high vacuum, is effective. The results of TDS analysis on a sample with Ni/Au plating on SUS material are presented. The release of H2, HCN, H2S, and HCl from the plating film was confirmed. Additionally, quantitative values were calculated.

TDS: Thermal Desorption Gas Analysis Method

TDS is a method that heats samples in high vacuum (1E-7 Pa) and detects the gases that are released. By heating the sample at a constant rate in high vacuum, it is possible to confirm the temperature dependence of even trace amounts of desorption (at the monolayer level). Additionally, for some components, it is also possible to calculate the number of molecules of the desorbed gas. We will introduce examples of TDS applied to representative materials.

From July 15 (Tuesday) to July 20 (Sunday), 2025, the "42nd Daihatsu Japan Open 2025 Badminton Championships" was held at the Tokyo Metropolitan Gymnasium. We would like to report on the motion capture experience session conducted by Yonex Co., Ltd. at the venue. During the experience session, participants were asked to swing three different types of rackets from different generations, focusing on whether there were differences in their top speeds. The measurement was conducted using the same Raptor-12HS system utilized at the Yonex Performance Innovation Center (Blue Lab). This was a valuable opportunity to experience the research equipment that is not currently open to the public and to see what kind of measurements are being conducted! ---[Yonex Co., Ltd.

Hello, this is the public relations department of KAITAKU Co., Ltd. in Okayama City, Okayama Prefecture! Recently, our wooden lightweight hyper CLT sheet has been officially registered with the Ministry of Land, Infrastructure, Transport and Tourism (NETIS number: TH-250021-A). The decisive difference between hyper CLT sheets and conventional temporary materials lies in the "exit" after their durability period ends. The hyper CLT sheet (NETIS number: TH-250021-A) is not discarded after its role on site is finished; instead, it is reused as chip fuel for biomass power generation. • Made: It is made from **wood (thinned timber)**, resulting in low environmental impact. • Used: It significantly contributes to reducing CO2 on site. • Converted to energy: Once its durability period is over, it becomes chip fuel for biomass power generation, ensuring that no resources are wasted. In this way, a **"complete circular" system** is established that connects materials to energy. Additionally, these initiatives can serve as a strong appeal for creativity related to construction performance. Please try the hyper CLT sheet (NETIS number: TH-250021-A)!

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

About a month ago, I took the Sanyo Electric Railway to the Hanshin Electric Railway express train from Himeji to Osaka on a Sunday. The important point here is that it was a "Sunday." The decisive difference from usual days is that there were "families" on board. I had somewhat anticipated this, but nowadays, almost 100% of parents are completely absorbed in their smartphones, ignoring their children who might be standing behind the driver's seat, shouting, or doing anything else. In fact, they even hand another smartphone to their child, effectively using it as a babysitter. At this rate, it's no wonder that these children will grow up to be adults with communication disorders.

On November 6th (Thursday) to 7th (Friday), 2025, we held the "Human Body Day 2025" at the NAC Image Technology Akasaka Multi-Purpose Space. We have uploaded videos of the highlights from each company and the presentations that took place on the day to our website. We encourage you to take a look. ---[Report on Human Body Day 2025 is here]------------------- https://info.nacinc.jp/jintaiday2025-report ------------------------------------------------------------------------- On the day of the event, participants were able to experience a wide range of products in a hands-on session format, including motion capture, force plates, eye tracking, and human body analysis software. We received numerous comments from attendees expressing high satisfaction, saying, "It was great to gain various information all at once," which makes us very happy. NAC Image Technology will continue to provide "valuable products to our customers." We hope you will join us for our next event as well.
