A semiconductor device with a thinned semiconductor chip and a method for producing the latter is disclosed. In one embodiment, the thinned semiconductor chip has a top side with contact areas and a rear side with a rear side electrode. In this case, the rear side electrode is cohesively connected to a chip pad of a circuit carrier via an electrically conductive layer. In another embodiment, the thinned semiconductor chips of this semiconductor device according to the invention have low-microdefect edge side regions with semiconductor element structures and edge sides patterned by etching technology.
