Abstract
A semiconductor component with an integrated circuit has a cooling body as a heat sink and a temperature sensor thermally connected thereto, whose resistance is dependent on temperature. The temperature sensor contains a thin film measuring resistor, which is applied to an electrically insulating surface of a foil-like substrate, and the total thickness of the temperature sensor lies in a range of about 10 &mgr;m to 100 &mgr;m. The thin film measuring resistor is formed as a planar component, with the temperature sensor being arranged between the integrated circuit and the cooling body. The thin film measuring resistor is provided on one side with a thermal coupling layer bordering on the cooling body, while on the other side the resistor has a substrate bordering on a heat distributor, which at least partially surrounds the integrated circuit.
