What is the function of chemical IC testing? The following aspects can be measured.

ChemistryIC testingIntegrated circuit testing is mainly used to evaluate the chemical composition, performance, and stability of chips. Specifically, it can measure the following aspects:

1. Material composition analysis

· Element compositionDetermine the elemental composition and content of chip materials (such as silicon, silicon nitride, metals, etc.).

· Impurity detectionIdentify and quantify potential impurity elements in materials that may affect chip performance.

2. chemical stability

· Corrosion resistanceEvaluate the resistance of chips to corrosion under different environmental conditions, such as humidity, temperature, and chemical media.

· Aging performanceAnalyze whether the material will undergo chemical changes after long-term use, which will affect its performance.

3. Thermochemical testing

· thermal stabilityThrough thermogravimetric analysis（TGA or differential scanning calorimetry (DSC) are used to measure the mass change and thermal characteristics of materials during heating, in order to evaluate their stability at high temperatures.

· Phase transition analysisDetermining whether the material undergoes phase transition (such as melting, crystallization, etc.) during the heating process is crucial for the operating temperature range of the chip.

· Thermal conductivityMeasure the thermal conductivity of materials to understand their performance in thermal management.

4. Electrochemical performance

· conductivityEvaluate the conductivity of the material and determine its performance when current passes through it.

· Electrochemical stabilityAnalyze the stability of materials under the action of electric fields, especially in high temperature or high humidity environments.

application area

· Semiconductor industryEnsure the purity and performance of materials during the chip manufacturing process to improve product reliability and lifespan.

· Electronic devicesEvaluate the performance of electronic components under actual working conditions to ensure their reliability in extreme environments.

· Material developmentIn the process of developing new materials, utilizing chemistryIC testing evaluates the performance and stability of new materials.

summary

ChemistryIC testing and thermochemical testing are key means to ensure chip quality and performance, helping engineers and scientists identify potential issues, optimize material selection, and improve the performance and reliability of semiconductor devices.
