[Analysis Case] Evaluation of Nickel Plating Peel-off Surface by TOF-SIMS

Investigation of the causes of coating peeling and poor adhesion through TOF-SIMS analysis.

To investigate the delamination issue that occurred on the nickel plating over bronze, TOF-SIMS analysis was conducted. By forcibly delaminating the affected area and performing qualitative analysis with TOF-SIMS, siloxanes and potassium compounds (such as potassium chloride and potassium sulfate) were detected from the delamination surface. These components are believed to be the cause of the delamination.

Analysis case: Evaluation of foreign substances present in resin.

Evaluation of foreign substances in resin is possible using TOF-SIMS through cross-section processing of the sample.

When evaluating organic foreign substances present in resin, it may be difficult to assess them in their original state depending on the sample and analysis conditions. Therefore, we will introduce a case where evaluation became possible by cross-sectioning the resin to expose the foreign substances at the surface. After exposing foreign substances measuring several tens of micrometers that were mixed into epoxy resin through cross-sectioning, we evaluated them using TOF-SIMS. We were able to identify the components of the foreign substances and confirm their distribution.

[Analysis Case] Analysis of Discoloration Components in Fibers

It is possible to evaluate the organic and inorganic components on the fiber surface.

TOF-SIMS is a highly effective method for investigating the causes of foreign substances, contamination, and discoloration in various processes, as it allows for localized analysis of specific areas and simultaneous analysis of elemental composition and molecular information of organic and inorganic substances through the obtained mass spectrum.

[Analysis Case] Thermal Desorption Gas Analysis of Metal (Sn)

TDS analysis of low melting point metals

Sn is used as the main raw material for solder, which is also used in semiconductor manufacturing. The gases in the solder can cause void formation, so it is important to control the amount of encapsulated gas in the solder and its main raw material, Sn. The results of investigating the gases released by heating Sn to a temperature above its melting point using TDS analysis are shown below. By heating the sample above its melting point, it is possible to evaluate the surface-adsorbed components and the components of the encapsulated gas in the sample.

[Analysis Case] Evaluation of "Water" in Quartz and Glass Using SIMS

Depth-direction analysis of hydrogen using 'heavy water (D2O) treatment'

We will introduce a case where the permeability of water (H2O) in glass materials was evaluated by measuring the distribution of deuterium (D). When hydrogen (H) is already present, it is difficult to distinguish whether the hydrogen is due to the influence of water. Therefore, treatment with heavy water (D2O) was performed, and the distribution of the stable isotope deuterium was measured in depth using SIMS. By examining the depth distribution of deuterium, it is possible to estimate how deep the water has penetrated.

[Analysis Case] Evaluation of Transdermal Absorption of Indomethacin in Three-Dimensional Cultured Human Skin

Visualization of the distribution of active ingredients applied to cultured skin using TOF-SIMS.

TOF-SIMS identifies components from the mass of molecular ions, eliminating the need for labels such as fluorescent substances, allowing for imaging without their influence. Additionally, cross-sectional imaging enables the evaluation of distribution in the depth direction. In this study, a gel formulation of indomethacin was applied to three-dimensional cultured human skin, visualizing the distribution of the permeated active ingredient. As a result, it was found that indomethacin is concentrated on the surface side of the stratum corneum. Furthermore, depth profile analysis observed a gradual penetration towards the cell layers.

[Analysis Case] Evaluation of the Thermal Treatment Temperature Dependence of Organic Films by TDS

You can confirm the changes in degassing due to differences in the baking temperature of the sample using TDS.

TDS can evaluate the temperature dependence of the desorption of inorganic and organic gases that are released with increasing temperature. Therefore, it is effective for assessing the degassing of samples based on the baking temperature. The results of TDS analysis after baking the resist film at 50°C and 200°C are shown. It was confirmed that the degassing peaks detected up to 200°C after "baking at 50°C" were not detected after "baking at 200°C."

TDS is a method for real-time detection of desorbed gases while heating the sample in high vacuum or maintaining a constant temperature. An example is shown where a SiN film on a Si substrate was held at 350°C to investigate the amount of H2 desorption. In simple heating, a desorption peak was observed around 500°C, but during the temperature hold at 350°C, the detection intensity of H2 decreased, and a desorption peak was observed upon re-heating.
