Primary owner of inline functional SRAM and logic yield in the development of IBM's 14nm and 7nm semiconductor microprocessors. As a hardware engineer at IBM, I work as the primary specialist in regards to SRAM and logic related defect monitoring and analysis.Daily responsibilities include tracking and monitoring SRAM yield and analyzing bit fail maps to diagnose chip and wafer level electrical fails. Extensive data mining for correlations and trend analysis are required to isolate device flaws and improve product yield. Coordinate daily with multiple engineering teams in the microprocessor design and fabrication process to communicate findings. Some notable achievements:• Expanded data analysis infrastructures with existing data-mining tools to perform various characterization and yield analysis of IBM SRAM technology.• Discovered and investigated discrepancies in the critical dimensions of device gate and its impact on low voltage yield loss. This resulted in a drastic improvement of low voltage 4 Meg SRAM yield and fixed a systematic defect in the lithography process.• Analyzed the impacts of device gate height to yield and metrology parameters to help evaluate whether the increased performance justifies the potential yield loss.• Tracked and analyzed large defect signatures which revealed silicon oxidation occurring during the gate contact etch process as the wafers sit too long in the foup. This discovery and fix resulted in a 20% SRAM yield increase.

Part of an engineering team working on low cost robotic prostheses for amputees with the capability of recreating tactile feedback and proprioception. In charge of designing, testing, and improving the electromyography (EMG) circuits for robotic prosthesis control.Built 4 different prototype variations of the circuits to experiment with bipolar and unipolar power supplies as well as figuring out what causes noise and how to eliminate that noise.Final circuit included a unipolar power supply with a LIPO battery with internal noise reduced significantly.Experimented with the ground circuitry of the EMG sensors and experimented ways to eliminate external noise.Designed and experimented with circuits for pressure sensors to be used tin prosthetic finger for tactile feedback via electrical stimulation to the user.

Researched and assisted in the design of the control system for textile slub machines. Worked with and tested servo dynamic motors. Utilized VHDL programming to control and test servo dynamic motors.

Worked as a paid teaching assistant in both discursive and technical English writing. Communicated with students with both Thai and English.
