e-Beam Engineering: Developing and supporting the various electronic systems related to electron beam functionality, including single-beam and multi-beam systems.

Assisting introductory electronics students with their lab assignments with a pedagogical emphasis on circuit debugging and systems interconnection. Duties include verifying circuit solution performance, approving annotated schematics, and clarifying circuit theory. Supporting students in ENGS32: Electronics (Linear & Digital Circuits) & ENGS26: Control Theory.

Prototyped and developed an ultra-low-noise current driver (PCBA 4-layers) to replace those currently in the wafer defect inspection system eSL10 (https://www.kla-tencor.com/esl10-ebeam-inspection). Capable of providing ±3 A & ±3.5 V reliably with a robust control loop for current control. Design features: PI controller, minimal loop area, multistage output filtering, & isolated copper for conduction. Evaluated leading edge giga-sample ADCs for future integration into electron beam… Show more Prototyped and developed an ultra-low-noise current driver (PCBA 4-layers) to replace those currently in the wafer defect inspection system eSL10 (https://www.kla-tencor.com/esl10-ebeam-inspection).

• Spearheaded the company’s dimensioning system transition from traditional optical comparators to automatic image dimensioning machines. • Programmed a previously unused, state-of-the-art KEYENCE Measurement System to automatically inspect the dimensional quality of the company’s manufactured parts. The machine was subsequently moved onto the manufacturing floor for machinists, engineers, and inspectors alike to use in their quality assessments.

• Independently drafted engineering plans, using CADD (SOLIDWORKS & AutoCAD), for production line tools that needed to be fabricated.• Assisted engineers in making production plans for use in marketing.
