Abstract:
A substrate processing system comprising:a substrate holder, located within a chamber, that holds a substrate during substrate processing; a gas delivery system for introducing a reactant gas mix into said chamber to deposit a layer over said substrate; a pump coupled to a gas outlet for controlling the chamber pressure; a controller for controlling said gas delivery system and said pump; a memory coupled to said controller comprising a computer-readable medium having a computer-readable program embodied therein for directing operation of said processing system, said computer-readable program comprising: instructions for generating a deposition pressure within said chamber of between 10-50 torr and for heating said substrate to a temperature greater than or equal to 580Â° C. and for controlling said gas delivery system to introduce a reactant gas mix including a silicon source gas, a boron source gas and a carrier gas into said chamber to deposit a insitu boron doped silicon film over said substrate positioned on said substrate holder, said instructions introducing a said reactant gas into said chamber at a first rate and controlling said chamber pressure so that said reactant gas mix has a residence time of less than or equal to 3.0 seconds.
