Abstract:
A method of forming a semiconductor device includes forming an active region in a first side of a silicon carbide substrate, the silicon carbide substrate having a second side opposite the first side and forming a contact pad at the first side. The contact pad is coupled to the active region. The method further includes forming an etch stop layer over the contact pad and plasma dicing the silicon carbide substrate from the second side. The plasma dicing etches through the silicon carbide substrate and stops on the etch stop layer. The diced silicon carbide substrate is held together by the etch stop layer. The diced silicon carbide substrate is attached on a carrier. The diced silicon carbide substrate is separated into silicon carbide dies by cleaving the etch stop layer.
