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.

"With high-precision dimming settings of 256/1000 gradations, you can achieve your desired results." The new 1-channel dedicated model LLBLM-A maximizes the performance of high-brightness LEDs. It offers high light stability through constant current control and flexibly accommodates a wide range of inspection and lighting applications with three types of interfaces: parallel, RS232C, and LAN. In addition to intuitive operation via the front panel, it supports high-precision dimming with 256/1000 gradations (256 gradations in parallel mode). The available emission colors are G (green) and B (blue). This new model balances stable light output with ease of use. For more details, please feel free to contact us.

Last month, we held a winter safety conference organized by our company. We have compiled the details and atmosphere of the day, as well as information on winter labor accidents, into a PDF. We would appreciate it if you could take a moment to read it.
