Fab Technician 1

Job Description

Under supervision, operates and supports MOCVD manufacturing processes in a semiconductor cleanroom environment. Performs routine wafer handling, equipment checks, recipe execution, production tracking, data recording, preventive maintenance support, and shift passdown activities while following documented procedures, safety requirements, cleanroom protocols, and quality standards. Escalates abnormalities promptly to supervision, engineering, maintenance, or safety contacts to protect personnel, equipment, product quality, and schedule commitments.

This department is a 24/7 operation. Candidates must be flexible in working weekend and night shifts as appropriate.

JOB RESPONSIBILITIES

Change into cleanroom garments and required PPE per standard operating procedures so cleanroom standards, contamination control, and personal safety requirements are met.

Clean and maintain work surfaces, wafer handling tools, vacuum wands, transfer fixtures, carriers, load stations, wet benches, and related MOCVD support areas per procedure or whenever contamination is suspected, so risk of particle or product contamination is controlled.

Complete assigned lab tasks, daily equipment checks, chamber/support-area cleaning, consumable checks, and scheduled preventive maintenance support for MOCVD tools and associated equipment.

Record production, PM, metrology, recipe, lot, gas, chemical, material, and equipment status data in required systems and logs so process quality, traceability, and equipment readiness can be monitored.

Communicate clearly and promptly so questions, abnormalities, and handoff items are identified and addressed in a timely manner.

Review and provide verbal shift overlap with operators, technicians, engineers, and supervisors as needed.

Read, write, and send accurate shift passdown covering tool status, lot status, open issues, safety concerns, material needs, and next steps.

Notify supervisor, engineering, maintenance, facilities, or ERT contacts of process problems, tool alarms, safety issues, low gases or chemicals, leaks, abnormal tool conditions, wafer damage, or any area of concern.

Perform required pre-run checks per standard operating procedures before processing product so misprocessing, contamination, and unsafe operation are avoided:

Verify MOCVD tool status, chamber readiness, interlocks, alarms, room conditions, chiller status, and required utilities/gases are within acceptable limits.
Confirm the lot is tracked in the applicable manufacturing execution system before processing.
Verify the previous process step is complete, the traveler is current, and the correct recipe, run conditions, and tool are selected.
Verify wafer identification, lot number, carrier, quantity, orientation, and traveler information match before loading.

Handle, load, unload, and transfer wafers carefully using approved tools and procedures so wafers are not broken, scratched, contaminated, misidentified, or misprocessed.

Execute assigned MOCVD production activities such as wafer preparation support, recipe loading/running, growth monitoring, run completion checks, wafer inspection support, and post-run documentation in accordance with approved procedures.

Assist engineers, maintenance personnel, and experienced operators with troubleshooting support, chamber-related tasks, consumable changes, inventory checks, and continuous improvement activities within training and authorization limits.

Prior to the end of shift, organize the work area, update passdown, place work in a safe and clear handoff condition, clean tables and workstations, clear clutter, return tools/materials to proper locations, and communicate open items to the next operator.

Follow all quality, safety, environmental, attendance, cleanroom, chemical handling, gas safety, wafer handling, and company policies as specified in procedures, training, permits, or other applicable requirements so personnel safety, product quality, productivity, and compliance standards are met.

Qualifications Experience/Performance

Minimum 2 years of semiconductor manufacturing, cleanroom, wafer fabrication, or related technical manufacturing experience preferred; MOCVD, epitaxy, high-vacuum equipment, or compound semiconductor experience is a plus.
Education:

High School diploma or equivalent required; technical certificate or Associate degree in Electronics, Semiconductor Technology, Manufacturing Technology, or related field preferred.
Able to read, write, speak, and understand English; able to perform basic math and accurately complete production records, travelers, logs, and system transactions.
