摘要: A mask (12) is applied to a silicon carbide substrate (11) in order to etch the substrate (11). The material used for the mask (12) has a Mohs hardness factor greater than 4 in order to prevent sputtering material from the mask (12) onto the substrate (11). An oxygen and sulfur hexafluoride plasma is utilized to perform the etch.
