Custom Process Development

Partner with Science Foundry to scale your prototype to production

Science Foundry works with clients across diverse industries, guiding projects beyond the scope of our Standard Technologies from concept to full-scale production.

Our engineers bring specialized expertise and hands-on support to every stage of development, complementing the wide range of advanced tools and capabilities available at Science Foundry. With deep knowledge in material and layer integration, we can create bespoke solutions utilizing non-standard materials rarely available in CMOS foundries—such as gold, noble metals, polymers, piezoelectrics, glass, quartz, III-N semiconductors, and more.

Production Process Overview

Production Volume

Chart showing how production volume increases. Chart showing how production volume increases.

  1. Feasibility Review

    Review prototype specifications and process flow to determine feasibility in our fab.

  2. Development Runs

    We collect data, identify issues, and adjust tools as we repeat the production process at least three times.

  3. Pre-Production

    Process validation at a large scale and any final adjustments before full-scale production.

  4. Production

    Production of devices at desired volume and schedule based on agreed specifications. 10s to 1000s of wafers.
