** Process Engineer
** In this critical role, you will be responsible for a broad range of backend wafer fabrication processes within MACOM’s internal wafer fab. Key areas of responsibility include dicing, scribe & break, grind/polish, glassing, wafer bonding, and mount/dismount operations. You will also provide support in other process areas as needed and serve as backup coverage for additional operations within the upstairs fab.

This position encompasses both the development of new manufacturing processes and the sustainment and continuous improvement of existing production processes. The product portfolio includes technologies based on GaN, GaAs, Si, and InP platforms, offering opportunities to work across a diverse range of semiconductor products and applications.
** Main Duties and Responsibilities*
* • Develop, sustain, and continuously improve wafer fabrication processes in close collaboration with Device Engineering, Integration Engineering, and Business Unit design teams.
• Serve in a hands-on engineering role requiring a broad understanding of wafer fabrication equipment and processes. Responsibilities include the setup, qualification, optimization, and troubleshooting of automated equipment used for dicing, scribe & break, wafer grinding, edge grinding, chemical-mechanical planarization (CMP), polishing, wafer bonding, glassing and mount/demount operations.
• Drive process performance to meet factory objectives by planning and executing experiments, fully characterizing processes throughout the development cycle, and implementing improvements in quality, reliability, cost, yield, process capability, productivity, and safety. Evaluate and optimize key process variables, including materials, methods, equipment, environment, and operator interactions.
• Provide daily process support, including equipment setup, program creation and maintenance, parameter optimization, engineering lot execution, equipment troubleshooting, and support for production teams in identifying, investigating, and dispositioning nonconforming material.
• Take ownership of assigned process areas from concept through production. Responsibilities include equipment selection, process and equipment qualification, development of operating procedures and work instructions, operator and technician training, and maintenance of routing and manufacturing documentation.
• Apply a strong technical foundation in electronics manufacturing while maintaining expertise in wafer fabrication processes and best practices.
** Key Competencies Required*
* • Demonstrated sound judgment, a solid understanding of semiconductor manufacturing processes, and a proactive, results-oriented approach to problem solving.
• Ability to develop and implement effective solutions using engineering fundamentals, statistical analysis, and…
