Abstract:
1. A substrate processing system, comprising: a vacuum chamber; a substrate supporter, located within the vacuum chamber, for holding a substrate; a gas manifold for introducing process gases into the chamber; a gas distribution system, coupled to the gas manifold, for distributing the process gases to the gas manifold from gas sources; a power supply coupled to the gas manifold; a vacuum system for controlling pressure within the vacuum chamber; a controller, including a computer, for controlling the gas distribution system, the power supply and the vacuum system, and a memory coupled to the controller comprising a computer readable medium having a computer readable program code embodied therein for directing operation of the substrate processing system, the computer readable program code including: computer readable program code for causing the gas distribution system to introduce a first process gas comprising a mixture of SiH computer readable program code for causing the gas distribution system to introduce a second process gas comprising He into the chamber to control the deposition rate of the first layer; and computer readable program code for controlling the gas distribution system to operate for a specified time period and for causing the first plasma enhanced CVD layer to be formed to a thickness which is an odd multiple, greater than one, of a wavelength of light to be used in a subsequent process operation on the layer.
