WebThe ideal for the inspection of EPI wafers. Un-patterned wafers inspection is becoming more critical due to the need to find defects earlier in the manufacturing process flow. Finding those defects is getting harder as critical dimensions shrink. Un-patterned wafer inspection looks for defects on unprocessed or bare silicon wafers. WebOur epitaxial growth process delivers excellence in: Excellent thickness control – 25 pt FTIR measurement on each wafer Maximum deviation from thickness target for all points …

Inspection, Metrology Challenges Grow For SiC

WebAbstract. We built a compact, common path, laser epi-illumination diffraction phase microscope (epi-DPM) for defect detection on a patterned semiconductor wafer. The wafer's underlying structure and buried defects with ∼ 100 nm size were measured. Original language. English (US) Title of host publication. 2012 IEEE Photonics Conference, IPC … WebSep 24, 2015 · One of the best ways to utilize SICA88 is to use it as a process monitor in wafer production, Epi process and device-making process for assisting root cause … Web“Optical inspection” includes systems that detect light diffusion and systems with differential interference contrast microscopes. These systems are for detecting unevenness in the wafer surface, but their sensitivity depends on their detection principle. 3.
