Abstract
Abstract A semiconductor arrangement including a carrier plate which is provided w a slit-shaped recess for receiving the semiconductor wafer. The semiconductor wafer has a solderable contact electrode on each of its major surfaces and an elastic protective lacquer coating around its peripheral surface. The semiconductor wafer is arranged within the recess such that its major surface intersects the plane of the carrier plate and the protective coating of the semiconductor wafer contacts the end surfaces of the recess so as to hold the semiconductor wafer in place. Metal contacts which lie along the planar surface of the carrier plate and border the longitudinal edges of the recess connect the semiconductor wafer in a desired electrical arrangement.
