cf4 device for Ultra High Voltage

Jul 24, 2020For etching silicon oxide, CF4 (tetrafluoromethane) is used. In a chamber, there are two electrodes; one is holding a wafer and a very high electric field created between these two electrodes. The chamber is first evacuated before introducing the gas. Radio frequency electrodes are then used to generate the
