> Designed photomasks for developing the new technology on the display panels, and successfully completed the photomask design, including iPhone, Apple Watch, iPad and MacBook development. Familiar with TFT-LCD, OLED display design and process flow.> Built the layout verification system and established a standard tape-out procedure for masks using Python, Mentor Graphics and Synopsys tools, which significantly improved working efficiency and decreased errors compared to checking by the human eye.> Optimized pixel layout on masks by optical proximity correction tools that enhanced image errors due to process effects, and successfully applied it on ultra-high-resolution panels.> Proposed and implemented solutions for panel failure.

> Developed Layout Versus Schematic (LVS) command file in the process design kit by using Mentor Graphics, Synopsys, and Cadence tools for 28nm process and others, which supported customers in IC design companies to increase the chances of first-pass successful silicon chip design.> Built Quality Assurance flow by using EDA tools in the Linux system to ensure the accuracy of the LVS command files.> Created LVS command files that included duplicate code for an advanced process by developing TCL and Perl programming to increase working efficiency. >Assisted customer’s physical design flow and LVS failure analysis on the real chip design that effectively supported them for tape-out chip masks.

> Designed and developed TFT-LCD panel and touch panel for digital cameras, and successfully put them into mass production in Sony, Samsung and Canon products.> Optimized the TFT array design by using Half Signal Line technology in panels and SPICE circuit simulation that successfully developed high-resolution displays with a lower cost to increase the market competition for our company.> Performed display mask design and complete layout verification by using Mentor Graphics and Synopsys tools that completed masks tape-out without any errors.> Successfully launched four patents in the U.S. after analyzing failures on the panel and solving them with new pixel design or layout methods.
