[Analysis Case] TDS Analysis of Glass Samples

It is possible to analyze desorbed gases by temperature increase even with transparent samples that allow infrared rays to pass through.

The temperature-programmed desorption gas analysis method (TDS) is a mass spectrometry technique that directly heats a sample by irradiating it with infrared light and monitors the gases generated at each temperature. When analyzing samples that cannot absorb infrared light, such as glass substrates, it is possible to conduct the analysis by changing the sample stage from transparent to black. The black stage absorbs infrared light, raising its temperature, which in turn increases the temperature of the sample through thermal conduction, generating gases.

[Analysis Case] Estimation of Detachment Components by TDS

We will compare the outgassing patterns of multiple masses.

The analysis results of TDS may show multiple components detected for a single mass-to-charge ratio (m/z). Even in such cases, it is possible to estimate the components desorbed by heating by measuring multiple masses and comparing the desorption patterns. Using the TDS analysis results of W films on Si substrates as an example, I will explain the estimation methods for water and ammonia (m/z=17), as well as organic substances and argon (m/z=40).

[Analysis Case] Thermal Desorption Gas Analysis of Organic Films (TDS)

It is possible to evaluate the outgassing components of organic matter in a vacuum environment.

TDS is a method that heats samples in a vacuum environment and monitors the gases that are released. When measuring organic substances, it can be difficult to obtain accurate measurements due to contamination of the equipment from large amounts of gas release. However, by adjusting the sample amount and analysis conditions in advance to control the amount of gas released, analysis becomes possible. Below are the results of TDS analysis conducted on organic films. We were able to capture the phenomenon where surface-adsorbed water is released at low temperatures, and the intensity of gas release increases with rising temperature.

[Analysis Case] Evaluation of Cu Surface Discoloration Using AES and SEM-EDX

It is possible to perform elemental analysis with a shallow detection depth while conducting SEM observation.

SEM-EDX analysis and AES analysis are suitable for simple investigations of discoloration and foreign substances on metal surfaces. However, when the discoloration or foreign substances are thin or small, AES analysis, which provides information from very shallow areas of the surface (about 4-5 nm), is effective. The AES equipment owned by MST can acquire SEM images, allowing AES analysis to be conducted while confirming the areas of interest using SEM images. In this case study, we will present data comparing the evaluation of discoloration on the Cu surface using AES analysis and SEM-EDX analysis. Additionally, we will also present the results of AES depth direction analysis.

Examples of TDS analysis by representative materials and purposes

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.

[Analysis Case] Evaluation of Coating Film on Injection Needle Surface

Visualization of the distribution and coating condition of water-repellent films, coatings, and membranes.

Medical injection needles reduce puncture resistance and lessen the physical burden on patients by coating the surface of the metal tube with silicone. To maintain the performance of the needle, it is important that the entire surface is covered with a coating film. This report introduces a case where imaging analysis of the opening at the tip of the injection needle was conducted using TOF-SIMS to evaluate whether the coating film was applied. Since TOF-SIMS detects information from the very surface, it can assess the condition of the coating film without detecting the underlying elements.

[Analysis Case] Evaluation of Gold Thin Film Adhesion on Wafer by XRF

Comparison of the amount of thin film components adhered between samples.

In fluorescent X-ray analysis (XRF), a simple evaluation of elemental distribution is possible. In this case study, we used a deposition device to create films of arbitrary amounts of Au on 4-inch Si wafers A and B as samples, and compared the distribution and total amount of Au. The results of the surface analysis confirmed the distribution state of Au (Figures 1-4). Additionally, by comparing the adhesion amounts based on the Au intensity from the XRF spectra obtained from each pixel, we confirmed that wafer B had more Au than wafer A (Figure 5).

[Analysis Case] Corrosive Gas Analysis by TDS

You can check for gases that have a negative impact on the product.

Corrosive gases such as etching gases have a significant impact on the degradation of semiconductors, electronic components, and devices. Below, we present an example of capturing corrosive gases using TDS (Temperature-Programmed Desorption Gas Analysis). It was confirmed that HCl, a corrosive gas, desorbs with the increase in temperature of the sample. Since TDS can capture desorption in the m/z range of 2 to 199 while heating, it is effective for investigating the types and amounts of corrosive gases as well as their temperature dependence of desorption.

Regarding interface and depth direction resolution

SIMS: Secondary Ion Mass Spectrometry

The SIMS analysis profile of the interface between different materials changes with a certain width in the depth direction. This is due to the characteristics of SIMS analysis, which are influenced by ion beam mixing and the roughness of the sputtered surface. The detected impurities represent averaged information up to the mixed depth, detecting ions from regions with a width in the depth direction. Therefore, the interface position is generally defined as the location where the ion intensity of the main constituent elements reaches 50%.

Composite approach to the cross-sectional structure and surface shape of the negative electrode, as well as elemental mapping images of the active material cross-section!

One of the causes of capacity degradation at the negative electrode of lithium-ion secondary batteries is the formation of a film called SEI (Solid Electrolyte Interphase), which is created by interfacial reactions between the active material and the electrolyte, resulting in various lithium salt compounds complexing on the surface of the active material. To improve battery performance, control over the composition, thickness, and chemical bonding state of the SEI film is required. This document presents examples of evaluations of the SEI film formed on the surface of carbon-based negative electrode active materials for automotive batteries using SEM, TEM, TEM-EELS, TOF-SIMS, and XPS. *For more details, please refer to the PDF document or feel free to contact us.*
