Job description

Description

The Die Fabrication 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.

• Partner with Integration Engineers, Customers, and Other Development Engineers to execute experiments, 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.
• Guide and assist Process Technicians through challenging process steps.
• 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.
• Provide effective pass-downs to support uninterrupted operation in the Die Fabrication area.
• Sustain and improve processes for semiconductor bars and die fabrication.
• Partner with equipment engineering, operation, 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
• Sustain existing processes in the areas of, Die Fabrication, wafer scribing, pick and place of chips, chips-to-wafer bonding, wafer dicing, bar dicing, and bar polishing, recipe creations, microscope inspections, chip placement control, wafers, bars, and chips defects control, and relevant metrology for process control.
• Create and maintain operating specifications for production processes and equipment.
• Monitor process health with Statistical Process Control (SPC) and respond to out-of-control event following out-of-control action plans.

Requirements

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.

Bachelor’s or Master’s degree in Mechanical Engineering, Material & Science, Physics or Chemistry with hands-on lab experience

• Processing experience in a fab or a lab in the areas of Mechanical Engineering using robotics and programming
• Ability to make technical mechanical drawings using SolidWorks
• Programming experience with Visual Basic, Excel Macros, and/or Python
• Experience and good understanding of statistical concepts
• Basic understanding of algebraic concepts
• Data extraction, analysis, and reporting experience
• Basic understanding of Die Fabrication processing
• Ability to troubleshoot basic problems and address root causes
• Ability to understand all maintenance activity details required to ensure a healthy and repeatable process
• Ability to plan and prioritize activities, perform and monitor multiple overlapping tasks/operations to meet goals and timelines.
• Ability to operate robots, processing tools, write and run process recipes, inspect wafers/bars/chips under the microscope, and perform basic characterization related to Die Fabrication processing such as particles / defects metrology, and thickness / uniformity metrology
• Must be able to work offset shifts: Front-End Days (starts on Sundays, ends on Thursdays) or Back-End Days (starts on Tuesdays, ends Saturdays)
