Wet Etch Process Development Engineer

Job Purpose

The Wet Etch Process Development Engineer is responsible to help support the development of manufacturable, repeatable, and high yielding processes for state-of-the-art highly specialized devices in the fields of Aerospace, Defense, Bioelectronics, and High-Speed Communications.

Essential Responsibilities

Reasonable accommodations may be made to enable individuals with disabilities to perform these essential responsibilities.

  • Develop Wet Etch and cleaning processes for various dielectric, metal and metal oxide/nitride films, as well as different III-V materials.  
  • Sustain existing processes in the areas wet etching, resist stripping, and wafer cleaning. Familiar with toolsets from DNS, FSI, MEI, Semitool, SEZ, Vertex, and other wet benches.  
  • Create, own, and manage process etch recipes and specifications.
  • Develop suitable process control schemes leveraging visual inspections, automated defect inspections, and standard Wet Etch related metrology such as surface defects scans, or profilometry. Set up and own SPC charts.
  • Develop and perform etches on manual wet benches tailored to specific product needs.
  • Drive problem-solving within the area as relates to yield and/or quality issues.
  • Monitor and improve defectivity.
  • Support equipment availability improvements
  • Guide, assist, and mentor process technicians and manufacturing technicians. 
  • Define Out-of-Control Action Plans enabling the on-shift sustaining team to resolve issues.
  • Provide effective pass-downs to support uninterrupted operation for Wet Etch activities.
  • Partner with Integration Engineers, Customers, and Other Development Engineers to execute experiments, provide input on optimal recipes or toolsets, and adjust or optimize processes for Fab Operation.
  • Partner with Product Engineering and Integration to help ensure effective new products and process introductions as well as consistent device performance and quality.
  • Analyze metrology results and disposition lots based on data and pass/fail criteria.
  • Report and summarize results from the metrology analysis and provide guidance to Integration Engineering Team and Process Development Engineering Team.
  • Partner with equipment engineering, operations, and management to improve cycle time, tool availability, quality and product yields.
  • Using Document Control, Process Work Instructions, and Manufacturing Execution Systems, preserve working knowledge of all codes and standards applicable to assigned production equipment.
  • Assure that the manufactured products conform to specifications and application requirements.
  • Partner with Senior Development Engineering team and Integration teams to resolve deviations or technical issues by establishing a list of hypotheses, defining the experiment to validate or invalidate hypothesis, identify root-causes, implement corrective actions, document improved process, and train operations.

Supervisory Responsibilities


Work Environment

80%+ of work is performed in the Fab, which a temperature-controlled cleanroom environment that requires the use of a full-body gown, over-boots, over-hood, safety glasses, and other PPE. The use of personal protective equipment to prevent exposure to hazardous materials can be expected. Frequent gowning and de-gowning is required. Frequent interruptions, static noise, and alarms (auditory and flashing lights) can be expected.

Physical Demands

  • Frequently in a stationary position, often sitting and/or standing for prolonged periods (3 hours)
  • Frequently viewing a computer monitor for prolonged periods (3 hours)
  • Frequently walking around the Fab for prolonged periods (3 hours)
  • Occasionally required to push and/or pull 50+ lbs objects, such as tool components
  • Occasionally required to lift 50+ lbs and occasionally carry that amount short distances (# ft)
  • Occasionally required reach, bend, twist, squat, kneel, and stoop to access and work on tools in the Fab
  • May often require repetitive motions involving the wrists, hands, and/or fingers
  • May require different positions and motions in tight and confined spaces
  • Occasionally required to handle items using small ranges of motion (e.g. fingers and hands) and large ranges of motion (e.g., full-arms and shoulders) for carrying cassettes and lot boxes
  • Constantly required to wear PPE 

Required Education and Experience

  • BS, MS, PhD in Engineering, Materials Science, Physics, or other technical discipline
  • 5 - 10+ years of experience in processes
  • Previous fab experience as process sustaining or process development engineer.
  • Ability to operate processing tools, write and run Etch process recipes, perform, and interpret basic characterization related to Wet Etch processing with particles/defects metrology, sheet resistance, and thickness/uniformity metrology, and inspect wafers under the microscope.
  • Experience with Statistical Process Control (SPC)
  • Data extraction, analysis, and reporting experience
  • Ability to plan and prioritize activities, perform and monitor multiple overlapping tasks/operations to meet goals and timelines.
