Equipment Engineer; Semiconductor Manufacturing

Equipment Engineer (Semiconductor Manufacturing)

Summary

The Equipment Engineer works closely with the production line (wafer and chip), R&D, EHS (Environmental Health & Safety), and facility departments to equip AOI with the most up-to-date and state-of-the-art technology in manufacturing and research development, and to support the routine operation and future growth of the semiconductor products division. In this position, the engineer is also responsible for a variety of tasks such as managing equipment, monitoring status, equipment installation, routine maintenance, preventative maintenance (PM), automation, modifications, calibrations, decontamination, troubleshooting and repairing the tools for wafer process, wafer growth, and chip production groups.

Equipment engineers also maintain the spare parts inventory and equipment backup.

Job Duties

• For new equipment installation and qualification to meet the company long-term growth:
  • Review the design of the new installation.

  • Manage new equipment training, certification, safety, and job hazard assessment.
• For existing equipment management:
  • Track equipment performance and reduce downtime (MTTR and MTBF).
  • Analyze and troubleshoot equipment issues to find the root cause.
  • Co‑work with process engineers to support production line and R&D.
  • Work with tool/equipment vendors when issues cannot be taken care of in‑house.
  • Manage spare parts and backup equipment, reduce cost and improve operation efficiency.
  • Support internal, third‑party, and vendor audits including equipment annual physical count.
  • Participate in determining and providing an optimum plan of operation, equipment, space requirements, and related facilities for assigned areas.
  • Provide the production team with in‑depth training and technical guidance.
  • Develop/review/revise work instructions and procedures in support of manufacturing processes.
  • Help to resolve manufacturing constraints, ease the production line and reduce risk.
  • Support the development and implementation of new methods, processes, and equipment in the manufacturing operation.
  • Set up and maintain the preventive maintenance schedule.
• Manage SPD fab and clean rooms, including:
  • Lab temperature, humidity, partial pressure, particulate counts and air circulation.
  • DI water supply and purity monitoring.
  • Chilled water system management.
  • Toxic gas and high‑pressure gas management.
  • Work with EHS on toxic waste treatment including solid, liquid, and gas waste.
• Work schedule will often require on‑call for nights and weekends as any equipment related issue should be addressed and resolved immediately to minimize downtime to the production line.
• Other duties as assigned.

Supervisory Responsibilities

• Level dependent and may supervise other coworkers and technicians.

Qualifications

• Bachelor or Master’s degree in Electrical Engineering, Materials Science and Engineering, Physics, Chemistry, or related field required.
• Minimum 5 years of directly related work experience in the semiconductor manufacturing and cleanroom environment.
• Hands‑on experience in dealing with mechanical, vacuum systems, electrical, and liquid/chemical tools.
• Ability to design homemade equipment systems is a plus.
• Must be comfortable handling chemicals, including corrosive acids, bases, solvents, etc.
• Must be comfortable with wearing cleanroom attire (class 1000) every day without any make‑up.
• Extensive experience in developing or maintaining various wafer process steps including photolithography, wet and dry etching, chemical vapor deposition, metal deposition, and electrochemical plating is a plus.
• Familiar with inspection tools including optical microscope, profilometer, ellipsometer, and SEM.
• Familiar with LabVIEW, MS Access, SQL, or JMP a plus.
• Familiar with mask aligner, hot…
