HD8800 Series

HD8820 Photodefineable, positive, aqueous

This product is the latest technology for semiconductor stress buffer and packaging applications. It is positive acting for high resolution and develops using aqueous chemistries for lower total process costs.


  • Low modulus
  • High elongation
  • Low moisture uptake

Applications include:

  • Stress Buffer
  • Packaging

Cured films have good mechanical and thermal properties to hold up in the most demanding applications. Low moisture uptake and good dielectric properties protect vital circuitry.

  • HD8820 – Cured Film, thickness 4 – 10µm

NOTE: These materials use TMAH as an aqueous developer. TMAH is not supplied by HD MicroSystems™.
