WebMar 26, 2016 · There are a few reasons why polysilicon is preferable to a metal gate: The threshold voltage (and consequently the drain to source on-current) is determined by the work function difference between the gate material and channel material. When metal was used as gate material, gate voltages were large (in the order of 3V to 5V), the threshold ... WebPolysilicon, poly-Si, or polycrystalline silicon, is a material consisting of a number of smaller crystals or crystallites. Deposition of polysilicon is one of the most important CVD processes used in microfabrication. Polysilicon is composed from trichlorosilane (SiHCl 3) or silane (SiH 4) through the following reactions: Polysilicon is ...

WebThere are two common low-pressure processes for depositing polysilicon layers: 1) using 100% silane at a pressure of 25-130 Pa (0.2 to 1.0 Torr); and 2) using 20-30% silane (diluted in nitrogen) at the same total pressure. Both of these processes can deposit … Polysilicon Thin films of polycrystalline silicon, or polysilicon (also known as … Fab Area : Chemical Reaction.
