Abstract:
A substrate processing system for depositing a film comprising silicon and nitrogen on a substrate, comprising:a housing forming a chamber, the substrate being disposed in said chamber;a gas distribution system for distributing process gases to said chamber;a plasma generation system for forming a plasma from said process gases within said chamber;a controller, including a computer, for controlling said gas distribution system and said plasma generation system; anda memory coupled to said controller comprising a computer-readable medium having a computer-readable program embodied therein for directing operation of the substrate processing system to deposit said film, said computer-readable program including:a first set of computer instructions for controlling said gas distribution system to introduce a first process gas comprising silicon into said chamber at a first selected rate, said first selected rate causing said film to be deposited at less than about 2000 .ANG./minute;a second set of computer instructions for controlling said gas distribution system to introduce nitrogen into said chamber at a second selected rate which maintains a pressure in said chamber sufficient to permit a reaction including said first process gas and said nitrogen to proceed; anda third set of computer instructions for controlling said plasma generation system to form a plasma from said first process gas and said nitrogen, thereby depositing said film over the substrate.
