We will identify and observe the defective areas of power devices such as diodes, MOS-FETs, and IGBTs.
We perform optimal preprocessing for power devices such as diodes, MOS FETs, and IGBTs of all sizes and shapes, and identify and observe defective areas through backside IR-OBIRCH analysis and backside emission analysis. ■ Preprocessing for analysis - Backside polishing - We accommodate various sample forms. Si chip size: 200um to 15mm square ■ Defective area identification - Backside IR-OBIRCH analysis and backside emission analysis - IR-OBIRCH analysis: Supports up to 100mA/10V and 100uA/25V Emission analysis: Supports up to 2kV * We address a wide range of defect characteristics such as low-resistance shorts, micro leaks, and high voltage breakdown failures. ■ Pinpoint cross-sectional observation of leak areas - SEM/TEM - We select SEM or TEM observation based on the predicted defects and can conduct physical observation and elemental analysis of leak defect areas with precision.
