Abstract
Provided is a small-sized inexpensive semiconductor module in which increase of ON resistance and increase of turn-off surge voltage at low temperature are suppressed. The semiconductor module includes: a semiconductor switching element; and a stress application portion provided on one or each of a first surface and a second surface on an opposite side to the first surface of the semiconductor switching element, having a linear expansion coefficient larger than that of a main material of the semiconductor switching element, and having a larger thickness than the semiconductor switching element. The stress application portion generates compressive or tensile stress in the semiconductor switching element through thermal shrinkage or expansion of the stress application portion due to change in temperature. A threshold voltage at which the semiconductor switching element is turned on, decreases in association with increase of a magnitude of the compressive or tensile stress in the semiconductor switching element.
