SilcoTek high tolerance, 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.                                                                             
  • Less metal ion contamination and particulate generation, less fluid contamination for improved yield                                                                           
  • Improved durability and reliability for longer component life
  • Consistent performance for improved regulatory compliance

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
    • Etch:  Eliminate barrier contamination, increase life, eliminate burn-in
    • ALD:  Enhance purity, reduce carryover and corrosion
    • EPI:  Eliminate particulate generation, improve stainless steel corrosion resistance
    • OLED:  Improve yield and efficiency
    • Ozone:  Stable flow path




Semiconductor Application Data

Need an inert surface that's durable and corrosion resistant?  Dursan offers superior performance and durability, making it an ideal coating for sampling in challenging environments.

Common semicon chemicals like HBr can corrode process systems, Silcolloy®, our corrosion resistant CVD coating, can improve system corrosion resistance 3x or more.

SilcoTek high tolerance, precision CVD silicon 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.  Coat the entire flow path to assure maximum performance.

SilcoTek coated samples are also more effective in preventing metal ion leaching into solution than other common alloys, like Alloy C-22. In the image below, SilcoTek coated samples show low to no ppb metal concentrations, resulting in more effective corrosion protection.

Methanol C22 Soak

This image shows the amount (PPB) of metal contamination found after soaking the samples in methanol for 30 days. The Silcolloy-coated C-22 outperformed the uncoated C-22 by 1000x.

Method- Solvent Extraction ICP-MS. technique- Parts were soaked  in methanol for 30 days to allow for measurable metal extraction. Samples were then analyzed by mass spectroscopy to investigate metal ions present in solution.

The uncoated tubing (below left "A") retains methanol, resulting in unreliable and slow calibration and testing.  The SilcoNert coated tubing (right "B") retains very little methanol, resulting in fast response and accurate test results.  This enables cleanroom and other indoor or outdoor monitoring stations to provide consistent and precise results. 


Methanol adsorption VOC Analysis

SilcoTek® inert barrier coatings dramatically reduce outgassing of stainless steel surfaces, improving pumpdown efficiency and virtually eliminating surface burn-in requirements.  Coated vacuum and critical flow path surfaces improve process efficiency and productivity.

Chamber Pump down

Moisture and other contaminants don't stick to SilcoTek® coatings, improving SEM pumpdown and preventing product adulteration.
