Abstract

See full text

A semiconductor device is provided that includes a temperature sensing function that accurately senses a temperature. The semiconductor device includes a first semiconductor layer on a semiconductor substrate, and a temperature sensor. The temperature sensor includes: a sensing-body region of a second conductivity type that is disposed in the first semiconductor layer; a first region of a first conductivity type, and a second region of the first conductivity type that are arranged in the sensing-body region and are apart from each other; and a third region of the second conductivity type that is in the sensing-body region and is between the first region and the second region. A concentration of a first conductivity type impurity in the temperature-sensing conductive layer is higher than a concentration of a first conductivity type impurity in the drift region.
