Abstract

See full text

The present techniques relate to a semiconductor device having resistance which has a positive temperature coefficient and a suitable value, and to a method for manufacturing a semiconductor device having resistance which has a positive temperature coefficient and a suitable value. The semiconductor device related to the present techniques is a bipolar device in which a current flows through a pn junction. The semiconductor device includes an n-type silicon carbide drift layer, a p-type first silicon carbide layer formed on the silicon carbide drift layer, and a p-type second silicon carbide layer formed on the first silicon carbide layer. Then, the second silicon carbide layer has a positive temperature coefficient of resistance.
