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 4):
The semiconductor device according to  claim 1 , further comprising a buried layer formed below the magnetism sensing portion and between the semiconductor substrate and the semiconductor layer,\n the buried layer comprising:\n a first buried layer of the first conductivity type formed on the semiconductor substrate side, and having a higher concentration than a concentration of the semiconductor substrate; and \n a second buried layer of the second conductivity type formed on the semiconductor layer side so as to be in contact with an upper surface of the first buried layer, and having a higher concentration than a concentration of the semiconductor layer.
