The Plasma-Therm Shuttlelock PECVD deposition, CCP-Dep, system is used primarily for depositing low-stress silicon nitride, silicon dioxide, amorphous and silicon carbide layers on 4 inch wafers. It can also be used for depositing silicon oxynitride layers, which have not been characterized at this writing. The stress level in the nitride films can be controlled by varying the He:N2
To maintain cleanliness level, cleans of both the chamber and wafers are required prior to processing -
Substrates in clean category: Pre-Diffusion Clean
For semi-clean substrates: Standard Metal Clean (SRS100 + PRS1000) . Run Chamber clean (no dummies) and conditioning with clean dummies prior to run
