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.

In civil engineering sites, there are many instances where sheet boards are used for temporary roads, access roads, heavy machinery work yards, material storage areas, and pedestrian pathways. Traditional steel plates are heavy, which can require large cranes or heavy machinery for installation and removal, increasing the workload depending on site conditions. Hyper CLT sheet boards are civil engineering materials made from wooden CLT for civil use. The 5×10 board weighs about 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to handle even with small machinery, which allows for easier installation without the need for large cranes. They also contribute to reducing the burden of transportation, installation, and removal, as well as improving maneuverability on site. Recommended as a registered technology by the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," it is suitable for companies considering civil engineering, civil use, and civil CLT. This material is easy to use for creative proposals in public works, such as alternatives to steel plates, common temporary structures, temporary roads, and curing for material storage areas.

What is an Air Leak Tester? An "Air Leak Tester" is a device that pressurizes the inside (or outside) of a sealed workpiece with air and determines the presence of leaks based on pressure changes. When a master with no leaks and a workpiece with leaks are pressurized, the pressure on the workpiece side decreases, creating a pressure difference between the two. By measuring this pressure difference, the presence of leaks can be determined. Generally, differential pressure air leak testing is widely used, but Fukuda also offers products that utilize direct pressure leak testing and flow meters according to the leak rate, in addition to differential pressure leak testers. Since the air leak tester uses air as the measurement medium, it incurs no running costs and is environmentally friendly.
