The GSI is a Plasma Enhanced Chemical Vapor Deposition (PECVD) system configured to deposit SiO2, Si3N4, and SiOxNy on substrates up to 100mm diameter. This is a single wafer system that deposits film on one side of the substrate at a time. Deposition temperature may range from 100C to 380C. Standard recipes deposit at 200C or 380C. Substrate heating is accomplished with the utilization of a heater block. The heater block does not contain active cooling. This system includes a dual frequency RF power delivery system with 13.56MHz as the primary power component. High frequency utilizes an auto-matching network w/ built in V/I probe on the output and low frequency utilizes a fixed matching network. The 13.56MHz is superimposed onto the 420KHz (when RF1 and RF2 are both used) and is capacitively coupled through the showerhead electrode. A wafer carrier must be used for 100mm and smaller substrates. All component parameters (except temperature) are displayed in system interface as percentage of full scale (ex. RF1 set to 32 is interpreted as 32% of 1000W’s or 320W’s).
