General Information

This page contains information and links to recipes/datasheets spin-coated materials used in the facility.

Table of Contents
  • Underlayers
    • These are used beneath resists for both adhesive purposes and to enable bi-layer lift-off profiles for use with photoresist.
    • Datasheets are provided.
  • Lift-Off Techniques
    • Verified Recipes for lift-off using various photolith. tools
    • General educational description of this technique and it's limitations/considerations.
  • Holography
    • For 1-D and 2-D gratings with 220nm nominal period, available on substrates up to 1 inch square.
    • Recipes for silicon substrates are provided, and have been translated to other substrates by users.
  • Anti-Reflection Coatings:
    • The Photoresist Recipes section contains recipes using these materials.
    • Bottom Anti-Reflection Coatings (BARC) are used in the stepper systems, underneath the resists to eliminate substrate reflections that can affect resolution and repeatability for small, near resolution limited, feature sizes.
    • Datasheets are provided for reference on use of the materials.
  • Contrast Enhancement Materials (CEM)
    • The Photoresist Recipes section contains recipes using these materials.
    • Used for resolution enhancement. Not for use in contact aligners, typically used on I-Line Steppers.
    • Datasheets provided with usage info.
  • Adhesion Promoters
    • These are used to improve wetting of photoresists to your substrate.
    • Datasheets are provided on use of these materials.
