Senior Silicon Photonics Process Engineer - Heterogeneous Integration
Location: Dallas, TX, or Lehi, UT
Group: Kilby Labs
We can't predict what the future holds, but we know Texas Instruments will have a part in shaping it.
Kilby Labs is the advanced R&D and product development support organization within TI chartered to define and develop new and innovative technologies and solutions in collaboration with business units and customers.
As a member of Kilby Labs you’ll have the chance to interact with many product groups and functions, work with an interdisciplinary team, and bridge from lab to fab to develop technologies to enable new markets.
About the Position
Kilby Labs is seeking a highly motivated and experienced Silicon Photonics Process Engineer to lead the development and implementation of heterogeneous integration (HI) of non-Si modulator materials into high-volume silicon photonics. This role is responsible for the initial process development through volume scaling of all aspects of the HI process module including layer transfer and post transfer processing. The role requires working extensively across other internal teams including advanced process technology development, fab operations, chip design and test, and product engineering, to make innovative, high performance and cost-effective silicon photonics solutions, while also requiring a focus on high-yield, reliable, and cost-efficient manufacturing. For this role we are seeking a creative problem-solver who can develop unique, breakthrough technologies.
