[Analysis Case] Depth Direction Analysis of Degradation Components in GCIB_Ar Cluster Organic Materials

Component evaluation of organic EL layer structures and degradation layers using GCIB under controlled atmosphere.

This paper presents a case study analyzing the degradation components of organic materials that deteriorate due to atmospheric exposure, using GCIB (Ar cluster). The experiment utilized the organic EL material, Rubrene. Measurements of the atmosphere-exposed samples using TOF-SIMS revealed the presence of a mass (m/z 564) estimated to be Rubrene peroxide, as well as low molecular weight benzene-related masses (m/z 77, 105). It was confirmed that these degradation-related components exist at depths of approximately 1μm or more from the surface. *GCIB: Gas Cluster Ion Beam

[Analysis Case] Investigation of Degradation of Solid Polymer Fuel Cell Electrolyte Membrane

Evaluation of degradation leachate components by LC/MS and IC.

Solid polymer electrolyte fuel cells (PEFC) are attracting attention for their high output at room temperature, making them suitable for automotive applications, home cogeneration, and mobile use. In this study, we simulated the degradation of solid polymer electrolyte membranes using Fenton's reagent (a solution of hydrogen peroxide and iron ions) and investigated the degradation byproducts in the solution. Composition information of the degradation byproducts was obtained using LC/MS, while information on the eluted ions was acquired using IC.

[Analysis Case] Degradation Analysis of Organic EL Devices Using MSDM

By visualizing the mass spectrum, more accurate analysis is possible.

Organic EL (OLED) is used in various applications such as high-definition display panels and lighting, and the demand for layer structure analysis and degradation analysis is increasing. However, since it is formed by combining various organic materials, elemental analysis alone can only capture a portion of the phenomena. This document presents a case study where depth direction analysis data of OLED was obtained using TOF-SIMS, and insights into the degradation of the sample were gained through MSDM (Mass Spectra Depth Mapping).

[Analysis Case] TOF-SIMS Analysis of Solder Separation Cross Section

It is possible to evaluate the distribution of inorganic and organic substances in microdomains.

To investigate the causes of solder delamination, it is effective to conduct component analysis of the solder and the substrate interface. TOF-SIMS is a suitable method for evaluating delaminated areas because it can simultaneously analyze elemental composition and molecular information of organic and inorganic substances, as well as perform imaging analysis. This document presents a case study analyzing the cross-section of a delaminated solder area, confirming the distribution of substrate components, resin components, and organic components other than resin.

[Analysis Case] Valence Evaluation of Trace Metals in Ceramic Materials

It is possible to evaluate trace metals in ppm orders.

When designing and controlling the properties of various materials, it is very important to clarify the types and amounts of elements present in trace amounts in the base material, as well as their states of existence. The types and amounts of elements can be evaluated using methods such as SIMS (Secondary Ion Mass Spectrometry) and ICP-MS (Inductively Coupled Plasma Mass Spectrometry), but the evaluation of states of existence, such as valence and chemical bonding states, is effectively conducted using XAFS (X-ray Absorption Fine Structure) measurements with synchrotron radiation. This document introduces a case study where the valence of trace amounts of Ce in ceramic materials was evaluated as a measurement example.

Overview and characteristics of LDI-MS (Laser Desorption Ionization Mass Spectrometry)

Differences between LDI-MS and MALDI-MS

LDI (Laser Desorption Ionization) is a method that uses only the energy of ultraviolet lasers to sublime and ionize molecules. On the other hand, MALDI (Matrix-Assisted Laser Desorption Ionization) is a method that sublimates and ionizes molecules by exposing a sample mixed with a matrix to ultraviolet lasers.

[Analysis Case] Heating Degradation Test of Lithium-Ion Secondary Batteries

Samples after thermal degradation can be evaluated using LC/MS/MS, TOF-SIMS, TEM+EDX, etc.

The development of lithium-ion secondary batteries faces challenges such as improving performance, extending lifespan, and enhancing reliability. To address these challenges, it is important to understand the degradation mechanisms of the batteries. In this study, we conducted a heating degradation test to evaluate the degradation mechanisms caused by temperature. After the heating degradation test, we assessed samples that showed significant capacity reduction using LC/MS/MS for the electrolyte, TOF-SIMS for the anode surface, and FIB-TEM+EDX for the cross-section of the anode.

[Analysis Case] Qualitative Analysis of Acrylic Resin

It is possible to estimate components using TOF-SIMS analysis.

Acrylic resin has superior processability, transmittance, and safety compared to silicate glass, making it widely used as organic glass for windows in aircraft and automobiles, optical instruments such as lenses and prisms, medical materials, daily necessities, and crafts. Mass spectra of representative standard acrylic reagents were obtained using TOF-SIMS. In MST, by comparing the mass spectrum of the analyte with that of the standard reagent, it is possible to estimate the acrylic resin from the detected fragment ions.

[Analysis Case] Investigation of Contamination Causes on Silicon Wafers

Evaluation of contamination originating from gloves

In semiconductor device manufacturing, it is necessary to investigate what causes thin deposits that lead to defects in order to examine contamination processes. An analysis was conducted using TOF-SIMS on the deposits for which carbon was detected by EDX and quantified by XPS. When compared to the gloves used for standard samples in each process, similar trends were observed with gloves A and B. Furthermore, verification was performed by adhering the standard sample gloves to silicon wafers. As a result, it was found that they were similar to glove A. Adhering standard samples to silicon wafers for verification is an effective method.

[Analysis Case] Evaluation of Material Structure of Organic EL (OLED)

It is possible to identify components for each layer, pixel by pixel.

To improve the reliability of organic EL, which is expected to expand in demand in the future, detailed structural analysis, state analysis, and identification of degradation causes will become increasingly important. We will introduce examples of evaluating layer structures and materials using TOF-SIMS and LC/MS. With TOF-SIMS, we were able to evaluate the layer structure and the component information of each layer. We conducted analyses of the components revealed by TOF-SIMS using LC/MS and a fluorescence detector, allowing us to assess the emission wavelength and understand the structure of the components. Thus, the combination of TOF-SIMS and LC/MS enables detailed evaluations.
