摘要： A circuit incorporated IGBT is provided with a semiconductor substrate having an IGBT area and a circuit area which are adjacent to each other. In a semiconductor layer of one conductivity type in which a circuit element is formed in the circuit area, there is provided another semiconductor layer of another conductivity type which adjoins the circuit element and has an impurity concentration higher than that of the semiconductor layer of the one conductivity type. An electrode contacts the other semiconductor layer and is connected to an electrode of the IGBT. Carriers are ejected from the other semiconductor layer to the electrode of the IGBT, thereby making it possible to prevent an erroneous operation of the circuit.

摘要： A semiconductor substrate is partitioned into a main IGBT region and a protection circuit region by a p-type well portion which is formed therebetween in contact with an emitter electrode and which acts as a cut-off region. Both a detection IGBT and protection circuit elements are formed within the protection circuit region. Since excessive carriers flowing from the main IGBT into the protection circuit region can efficiently be extracted through the p-type well portion, a highly reliable and high precision protection circuit built-in insulated gate semiconductor device is realized that can precisely detect any overcurrent, and operate without causing malfunction in the protection circuit and time delay.
