Abstract:
Provided is a semiconductor device including a Hall element, in which a depletion layer is prevented from spreading to a magnetism sensing portion more reliably, and thus variations in characteristic are reduced. The semiconductor device, including: a semiconductor substrate of a first conductivity type; and a Hall element formed on the semiconductor substrate, the Hall element having: a magnetism sensing portion of a second conductivity type formed on the semiconductor substrate so as to be separated from the semiconductor substrate; and a semiconductor layer of the second conductivity type formed so as to surround side surfaces and a bottom surface of the magnetism sensing portion on the semiconductor substrate and has a lower concentration than a concentration of the magnetism sensing portion and a uniform concentration distribution.

Claim (Index 5):
The semiconductor device according to  claim 1 , wherein the semiconductor layer comprises an epitaxial layer.
