MNFL Tool Maint & Repair Tech

Job description

Requisition # 2018-8986
Department Prn Inst F/T Sci & Tech of Mat
Category Research and Laboratory
Full-Time / Part-Time Full-Time
Application Deadline


Support all cleanroom tool maintenance, troubleshooting and repair functions of the Princeton PRISM MNFL, including but not limited to vacuum tools, plasma reactors, thermal and plasma deposition processes, laser direct patterning tools, as well as back-end processing tools (bonding, dicing); in all functions such as pneumatic, high-purity gas handling, electronic, ultra high vacuum, RF, electromechanical and robotic. Repairs computers and control electronics associated with the operation of such tools. Designs and builds UL/CE compliant electronics to interrupt key tool functions in order to enable management control of access to tools including those using hazardous process materials (HPM's). Works with safety specialists and process engineers to ensure components do not present hazardous exposure (chemical, electrical, thermal) risk to staff or to lab researchers using the tools. Rigs, moves, installs new tools and brings them to the point of process qualification by engineers. Works and communicates easily with lab clients to understand relevant issues representing sub-optimal tool performance and seeks to immediately rectify underlying issues. Interfaces with field service representatives to both constantly learn new approaches and to ensure function to specification.


Ensure the proper operation of cleanroom tools by working with process engineers or by independently assessing process performance trends and pro-actively performing preventive maintenance. This includes tool inspection, diagnostics, teardown, repair, full reassembly (including tool skins) and documentation of effort for future reference. Documents and tracks tool age, use history, PM schedule and procedures and maintains the documented institutional memory of tool repair successes and failures.

This individual owns the primary responsibility among all staff for cleanroom process and support equipment troubleshooting, repair and modification. He or she will have a broad capability for troubleshooting and repairing tools used for microfabrication: vacuum and RF plasma-based thin film deposition and patterning tools. Backend tools. Lithography tools. Must be willing and able to kneel, squat, reach, and be comfortable working in confined spaces and in a cleanroom suit with hood, face cover, gloves and clean coveralls. Must be familiar with vacuum leak checking approaches. Plasma diagnostic skills using optical spectrophotometers a plus. Understands risks of oil based vacuum pumps and is capable of maintaining dry pumps.

Assist equipment installations by working with colleagues to ensure proper installation conditions, rig and move the tool to the use location, complete final connections, start-up and test. Support troubleshooting during qualification. Skill and experience in operating these tools is an added benefit but not as important as demonstrated electromechanical and vacuum understanding and skills. De-installs, rigs and crates obsolete tools and arranges for re-use or disposal. The individual knows when they have reached the end of their own skills and when it is appropriate to call in external resources or seek learning from other resources. Has a broad contact list of external resources.


Bachelor degree or equivalent required in 10-30 years practical experience. Must be willing to work a modified shift, coming in first thing in the morning (6-7 am), assess the status of the lab and tools in the lab as well as alarm systems for supporting (e.g., gas delivery) and supporting infrastructure. Must be willing and able to come in at nights or on weekends on-call to support unanticipated facilities, equipment and personnel events. Good with people. Good communicator. Respectful of students, colleagues, faculty, administrators and suppliers. Attitude is "get 'er done!" Diversity of skills is required. The ideal candidate will be a serial tinkerer--someone who loves to understand how things work--and finds challenge, opportunity and satisfaction in building, creating, problem solving and fixing something broken. Unafraid of the type of challenge, whether robotic, electronic, pneumatic, mechanical, electromechanical, RF, vacuum or laser. Multi-tasks.

Specific skills and experience to be demonstrated in an evaluation setting:
Vacuum troubleshooting and repair.
Electronics use, troubleshooting and repair.
Safe practices in lock-out / tag-out.
Fastidious in getting the job done, doing it properly and cleaning up when finished.
