Wafer size: 2-inch, 3-inch, 4-inch, 6-inch

Production capabilities

  • Aixtron MOCVD production platform
  • 25,000 square foot facility
  • Class 1000 cleanroom
  • State-of-the-art materials test and characterization suite



We engineer solutions that make next-generation epiwafer developments manufacturable. If it doesn’t scale, it doesn’t matter. Even the greatest technology won’t affect the industry if it can’t be replicated reliably and repeatedly at a reasonable cost. EpiWorks’ engineering team makes replication a reality by serving as a critical bridge between R & D and production. For R & D, we take out the guesswork, making EpiWorks’ developments reliable and manufacturable. The production team is served by engineering’s ability to troubleshoot and solve problems.

Research and Development

While the research team is always working to develop industry firsts, their ability to collaborate with your device engineers, designers, or fabrication team is where the real advantage lies. We are your Inside Source, and it’s this brand of collaboration that leads to rapidly developing high-performance, next-generation solutions.
