Developed, tested, and revised Reactive Ion Etching processes (for both front end and back end of line semiconductor manufacturing) and extensively troubleshot equipment and process faults to recover misprocessed wafers and return tools to desired production standards
Monitored and maintained 60+ Front End of Line and Back End of Line tool mainframes; transfer modules; and processing chambers specializing in Reactive Ion Etching (RIE), Ion Implantation, Gas Cluster Ion Beam Planarization (GCIB), Plasma Doping, Ashing, and Chemical Oxide Removal (COR)
Organized and tracked process module usage hours, and long-term processing trends, to adjust designated times between part replacements, based on empirical data, which saved money from unnecessary work and predicted when work was needed before product was damaged
Executed and organized experiments which reduced the total number of silicon wafers needed for tool monitoring and increased the efficacy of equipment monitors by updating qualifying process parameters to better mimic production conditions and provide more reliable data
Analyzed Statistical Process Control charts (combined with metrology wafer maps and monitor trendlines) to track, maintain, and improve quality control of manufacturing etch processes
Coordinated with workstation operators, integrators, and engineers to facilitate the transfer of processes between different platforms and develop new key programs for IBM (and partner companies including Global Foundries, Samsung, Lam, Tokyo Electron, and Applied Materials) involving FinFETs, Gate-All-Around FETs, Nanosheets, Magnetoresistive RAM, Resistive RAM, and Phase-Change Memory
Trained and certified workstation operators on proper tool operation to reduce the number of unnecessary operation interruptions and to increase both fab efficiency and overall product yield
Filed and awarded a patent on Metal Supervia Structures and have two Middle of Line Contact Processing patents pending
Skills Learned: Collection and analysis of process and trend data to troubleshoot and ameliorate quality control problems; Effective and efficient communication, between multiple engineering groups and companies, to streamline the recovery of hardware and minimize production down time.

Meticulously worked through procedures (circuit board, wiring and layout diagrams) to construct, wire, and solder new equipment and collaborated with crews from different departments to complete large scale construction projects and maintain existing railroad signaling equipment
Spearheaded the disassembly and categorization of hundreds of relays, and other electronic equipment, to streamline repairs
Revised, reviewed, and created over 100 circuit diagrams, using AutoCAD 2012, to ensure quicker updating and dissemination of hardware improvements.
