Maintain mass production project: 5M/2M CMOS sensor. Collaborated with QA team to finish reliability projects such as HTOL(168/500/1000), HTSL(504/1008) Designed and Maintained testing programs in ATE platform such as AMIDA A2020. Collaborated with The R&D team and the product team members to solve mass product issues. Developed the testing tool to analyze datalog in order to improve yield. Optimized the algorithm to reduce the production cost.
