Abstract

A semiconductor device according to the present invention includes a resistant heating element as a temperature regulation means on a circuit board. A semiconductor chip of the device is connected to the circuit board through connecting electrodes. A difference in temperature between the semiconductor chip and circuit board is kept at a fixed value by controlling the resistant heating element.
