Abstract:
1. A chemical vapor deposition system comprising: a deposition chamber having a substrate positioned therein; a vessel containing trisilane; a feed line operatively connecting the vessel to the chemical vapor deposition chamber to allow passage of the trisilane from the vessel to the chemical vapor deposition chamber; a source of an inert carrier gas operatively configured for transferring the trisilane through the feed line to the chemical vapor deposition chamber; a first temperature controller programmed to deposit an optionally-doped Si or SiGe film onto the substrate using the trisilane as a feed gas at a temperature higher than 525° C.; a gas flow controller comprising at least one set point, wherein the gas flow controller is set to introduce the trisilane and the inert carrier gas to the chamber at (a) a trisilane partial pressure in the range of about 1×10 a temperature-controlled bubbler in gas communication with the source of the inert carrier gas and the vessel containing trisilane.
