Semiconductor manufacturers are now employing a new “secret weapon” in the never ending quest for improved performance and yields. As [14 nm semiconductor](http://en.wikipedia.org/wiki/14_nanometer) production ramps up, elimination of process impurities become exponentially more critical. SilcoTek® high purity coatings solve the contamination problem by bonding high purity silicon to intricate surfaces in plasma etch systems like showerheads, fittings and tubing.

## Superior Corrosion Protection

SilcoTek® coatings improve corrosion resistance 8x or more, preventing reactive etch gases from corroding flow path surfaces and ultimately contaminating the wafer surface.

 

 

## Seeing Is Believing

Contamination of semicon etch streams is a potential major yield issue.  Immersion of coated and uncoated 316 stainless steel coupons in highly corrosive hydrochloric acid demonstrates how quickly a process stream can become contaminated.  The clear container shows no contamination while the green liquid shows severe leaching of metal ions after only 24 hours of exposure.

SilcoTek® coatings are compatible with commonly used chemicals used in semicon manufacturing process streams.  See the complete list:

SilcoTek's semiconductor R&D team has recently developed a modification to our [Dursan®](https://www.silcotek.com/dursan) coating that is tailored specifically to semiconductor manufacturers.  The carbon element of the original Dursan is almost fully removed, yielding a thin but durable silicon oxide (SiO) layer that prevents both erosion and corrosion in manufacturing processes.

- ### Insulative and chemically stable, minimizing loss
- ### Highly resistant to ozone
- ### Uniform, thin CVD layer for maximum performance
