Coatings for Semiconductor Manufacturing

Improve Corrosion Resistance, Purity, and Yield

Increase Return on Investment on Critical Manufacturing and Process Equipment


SilcoTek's inert, precision CVD silicon barrier coatings protect and improve critical surfaces throughout semiconductor process systems. Coating all critical flow path surfaces will prevent ion and particulate contamination & improve process yield. SilcoTek® coatings like Silcolloy®, Dursox® and Dursan® make critical flow paths corrosion resistant and inert, assuring process components are protected and free from yield-robbing metal ion contamination.

The benefits of an inert and corrosion resistant barrier coating include:

  • Improved corrosion resistance with less process contamination
  • Low outgassing for improved vacuum pump down.
  • Improve yields with less metal ion leaching, fluid contamination, and particulate generation
  • Improve durability and reliability for longer component life
  • Consistent performance improves process control

Coating Applications for Semiconductor Manufacturing.


Corrosion in semiconductor process flow paths can result in yield robbing particulates and metal ion release. SilcoTek corrosion resistant barrier coatings can be bonded to the most intricate internal flow path surfaces to dramatically improve the corrosion resistance and inertness of stainless steel and metal alloy surfaces.

Applications include:

  • Cleanroom VOC Testing
  • Product and SEM Testing
  • Process Gas Delivery
  • Corrosion Control
  • Etch and deposition
