[TOF-SIMS] Time-of-Flight Secondary Ion Mass Spectrometry
This is a method for structural analysis of the sample surface. Due to its sensitivity to the surface compared to other analytical devices, it is suitable for identifying organic contaminants on the very surface.
This is a method for structural analysis of sample surfaces. It is suitable for identifying organic contamination on the very surface due to its sensitivity compared to other analytical devices. Using a sputter ion source, it is possible to analyze the distribution of inorganic and organic materials in the depth direction. - Structural analysis and identification of organic and inorganic compounds are possible. - Coordination data from foreign substance inspection devices can be linked. - Qualitative analysis is possible from micron-order microforeign substances to several centimeters. - It is possible to analyze the very surface with high sensitivity. - Image analysis is possible. - Qualitative analysis of depth direction analysis is possible.
basic information
By reducing the amount of ion irradiation at one time, it becomes possible to maintain the molecular state of the surface and generate secondary ions. The obtained secondary ions are analyzed using a Time-of-Flight mass spectrometer.

[Analysis Case] Evaluation of Depth Profile Concentration Distribution of Alkali Metals in SiO2 Using C60 has been published.
Alkali metals such as Li, Na, and K are key elements in various failure causes in semiconductors. These are referred to as mobile ions that can move within the film during measurement, making it difficult to obtain an accurate distribution. In this study, by conducting depth profiling analysis using a C60 (fullerene) sputter ion source in TOF-SIMS, it was found that the movement of alkali metals can be suppressed even at room temperature. This measurement allows for qualitative and quantitative analysis of impurities within SiO2 films. ★★★★★★★★★★★★★★★★★ Please see the link for the analysis data ★★★★★★★★★★★★★★★★★

[MST Homepage] Analysis Case "Heating Degradation Test of Lithium-Ion Secondary Batteries" Published
The MST website has published analysis case studies. ◆Title Heating Degradation Test of Lithium-Ion Secondary Batteries ~Samples after heating degradation can be evaluated using LC/MS/MS, TOF-SIMS, TEM+EDX, etc.~ ◆Measurement and Processing Methods TOF-SIMS, TEM, LC/MS/MS, FIB, μ-sampling, lift-out, disassembly, atmosphere control ◆Product Field Secondary Batteries ◆Analysis Objectives Composition evaluation, identification, chemical bonding state evaluation, film thickness evaluation, degradation investigation, reliability evaluation ◆Overview The development of lithium-ion secondary batteries faces challenges such as performance enhancement, longevity, and reliability improvement. To address these challenges, understanding the degradation mechanisms of the batteries is crucial. In this instance, a heating degradation test was conducted to evaluate the degradation mechanisms due to temperature. After the heating degradation test, samples that showed significant capacity reduction were evaluated using LC/MS/MS for the electrolyte, TOF-SIMS for the anode surface, and FIB-TEM+EDX for the anode cross-section. ★★For detailed data, please refer to the link★★
