SKY Capacitance Diaphragm Gauge AllCeramic CDG025-C
All vacuum exposed surfaces of the SKY AllCeramic CDG are constructed of ultra-pure aluminum oxide ceramic, replacing the stainless steel tubing of our traditional CDG. This product is preferred in applications where metal contamination must be avoided.
Advantages
- No metal contamination
- Marginal zero drift
- Virtually corrosion proof - long sensor life results in reduced downtime thus reducing cost of ownership
- Superior accuracy and repeatability over long periods of operation
- Better long term and temperature stability
- Eliminates isolation valve (depending on operation mode)
- Less susceptible to particles and process by-products due to suprashield
- Fastest warm-up time
- Lower cost of investment
- Drop-in replacement of existing CDGs due to interface compatibility
Applications
- Etch, CVD and PVD processes
- Doping silicon using implantation or diffusion processes
- Oxidation
- Creation of gate oxide layer in the range of 100ō
- Creation of barrier layers (Ti, TiN, Ta and TaN as a protection layer between Silicon and Aluminum or Copper
