The degree of crystallinity and the uniformity can be controlled by optimizing process pressure and temperature parameters. The manipulation of process temperature can also used to control grain size and film stress.
Rogue Valley Microdevices offers a variety of Polysilicon films by tailoring deposition conditions. We can offer Polysilicon films in standard or small (fine) grain film composition, along with different film stress levels ideal for many MEMS specific applications.
