• Successfully led the project to achieve significant savings in material costs. • Established an EDA monitoring system to motior the material loss rate. • Established an EDA monitoring system to effectively track and enhance UPH/OEE performance. • Established new MMR system to improve the accuracy

R&R • Capacity Expansion • Timely generate expansion or build-up plan and align with factory team. • Communicate with BU (in US) and Corporate (in KR) for the optimal support plan • Actually execute support plan like transferring WW excess resources, purchasing / upgrading equipment • Control schedule including re-layout activities and equipment arrival/release etc to meet target in time • Layout Planning : Modify non-clean room space to clean room level, fully utilize limited space for production line. • Factory system enhancement and data analysis : UPH / OEE / System • Cost analysis : Collect each factors to analysis different case to charge customer cost adder Key Performance • Successfully to expand FCBGA/WLCSP/Test capacity for many times in Amkor • Re-design the Capacity model and import the macro to improve the calculation time. • Analyze data trend, verify and find the opportunity to improve the productivity • Build up the log analysis instead of measuring UPH by stopwatch • Compare the parameter and analysis it to improve the UPH • Build the Cost Analysis Function

R&R • Manager operator • Achieve target output and daily target schedule • Communicate with PP to control the daily input • Improve the productivity Key Performance • Improving the scrubber productivity, co-work with PE to control the recipe • Analysis Hold lot to deduct and combine the process • Breakdown the bottleneck to increase the UE to achieve the target output
