Engineering Technician

Wolfspeed•Fayetteville, AR

19d•Onsite

About The Position

The Engineering Technician will work in the failure analysis laboratory in Fayetteville, Arkansas, supporting customer returns, new product introduction, and continual improvement for Wolfspeed silicon-carbide-based MOSFETs and Schottky diode die, discretes, and power modules, as well as customer-built power modules. The technician will perform electrical testing, nondestructive imaging, deprocessing, cross-sectioning, and fault location to identify failure root causes and collaborate with teams to develop solutions. The role also assists the on-site Failure Analysis Engineer. The position supports engineering work involving prototype electromechanical systems, experimental circuitry, laser/light transmission devices, and specialized test equipment. It includes testing and troubleshooting from schematics, diagrams, descriptions, layouts, or defined plans; operational testing and fault isolation; and assistance with test-equipment design, construction, and checkout. The technician will develop electrical testing, chemical deprocessing, and CSAM cross-sectioning and polishing processes, and write controlled-document procedures. The role also supports laboratory chemical hygiene, waste disposal, safety, ESD prevention, 5S, tool ownership, and best practices while collaborating with laboratory technicians, engineers, and the Durham and Fayetteville failure analysis teams. Additional duties or assignments may be designated by management.

Requirements

A two-year degree or better in physics, chemistry, materials science, engineering (electrical, chemical, or materials), or a related field, or equivalent working experience in a failure analysis laboratory.
Working knowledge of semiconductor process technology and device functionality.
Strong soft skills, including technical writing, verbal communication, technical presentations, critical thinking, multitasking, flexibility with rapidly changing priorities, collaboration with remote teams, urgency, accountability, and ownership.
Ability to work in a laboratory in close proximity to others and remain on one's feet for up to eight hours per day.
Comfort performing chemical, mechanical, and high-voltage electrical processes.

Nice To Haves

Two or more years of hands-on electrical component failure analysis experience, including techniques such as CSAM, hotspot analysis, chemical, laser, and/or plasma deprocessing, mechanical cross-sectioning and polishing, SEM, and EDX; similar experience in wafer fabrication or packaging, cleaning, or etching may also be beneficial.
Two or more years of hands-on experience or working knowledge of microelectronic semiconductor devices and assembly/packaging, including discretes and power modules.
Experience with chemical handling and general laboratory procedures.
Hands-on electrical testing of semiconductor device components such as MOSFETs and Schottky diodes; silicon carbide experience is highly preferred.
Supervisory or project leadership experience.
