MACOM•Lowell, MA

22h•Onsite

About The Position

In this critical role, you will be responsible for supporting backend wafer fabrication processes, including grinding, polishing, glassing, wafer bonding, mounting/dismounting, and other operations within MACOM's internal wafer fabrication facility. You will also provide support across additional manufacturing areas as needed and serve as backup coverage for other operations within the upstairs fab. This position encompasses both the development of new manufacturing processes and the sustainment and continuous improvement of existing processes. The product portfolio supported by this role includes technologies based on GaN, GaAs, Si, and InP materials.

Requirements

Ability to develop solutions using formal education, statistical methods, and structured problem-solving tools.
Proven track record of solving technical problems, owning projects, meeting deadlines, and managing multiple tasks.
Strong sense of ownership, enthusiasm, and dedication to process improvement.
Ability to work collaboratively with cross-functional teams to enhance processes.
Excellent verbal and written communication skills, including technical writing for data summaries, findings, process specifications, equipment documentation, and work instructions.
Knowledge of optical component fabrication and polishing.
Knowledge of wafer polishing, Wafer Grinding, Edge Grinding, and CMP processes.
Hands-on experience in wafer fabrication processes.
Basic project management experience and ability to work with minimal supervision.
Strong presentation skills and ability to communicate effectively with all levels of management and across diverse departments.
BS in Engineering.
Minimum 8 years of relevant work experience in semiconductors / Wafer fabrication process.
Familiarity with typical material systems used in compound semiconductors and a solid understanding of device physics and IC processing.
Demonstrated knowledge of compound semiconductor processing in a wafer fabrication environment or similar setting.
Due to ITAR restrictions, applicants must be a U.S. Citizen or Permanent Resident.

Nice To Haves

Experience with data mining, statistics, SPC, DOE, Lean manufacturing, Six Sigma, and structured problem-solving methodologies is preferred.

Responsibilities

Develop, continuously improve, and sustain processes in close partnership with Device and Integration Engineering and Business Unit design teams.
Serve in a hands-on capacity requiring a broad understanding of wafer fabrication equipment and processes.
