Patent ID: 7327152

Claim:
An integrated test circuit arrangement having integrated test structures located on an integrated circuit substrate, at least one integrated heating element located on the integrated circuit substrate, an integrated detection unit, located on the integrated circuit substrate, which detects at least one physical property for each of the test structures, an integrated supply unit, located on the integrated circuit substrate, which supplies each of the test structures with a current or a voltage in switchable fashion independently of one another, and a control unit which is connected to outputs of the detection unit on an input side and which controls the supply unit dependent on the detection results; wherein at least one of: the detection unit contains at least one multiplexer unit, the inputs of which are electrically connected to a respective test structure, and an output of the multiplexer unit is connected to a first input of a comparison unit, a second input of which is electrically connected to a reference structure, the reference structure having at least one of a different construction and different dimensions than the test structures.
