Abstract
A silicon carbide chip array containing a silicon carbide substrate; a silicon carbide layer on top of the silicon carbide substrate; a first metal contact connected to the silicon carbide substrate; and two second metal contacts connected to the first portion and the second portion respectively. The silicon carbide layer is thinner and having lower doping than the silicon carbide layer. The silicon carbide layer includes a first portion and a second portion which are separate from each other. Each one of the second metal contacts forms a semiconductor device with the first metal contact. At least one of the first and second portions contains a side face which is inclined with respect to the silicon carbide substrate. Such a configuration enhances the breakdown voltage and reduces leakage current of the resultant silicon carbide diode array.
