Abstract:
A semiconductor chip includes a semiconductor body and a chip metallization applied on the semiconductor body. The chip metallization has an underside facing away from the semiconductor body. The chip further includes a layer stack applied to the underside of the chip metallization and having a number N1≧1 or N1≧2 of first partial layers and a number N2≧2 of second partial layers. The first partial layers and the second partial layers are arranged alternately and successively such that at least one of the second partial layers is arranged between the first partial layers of each first pair of the first partial layers and such that at least one of the first partial layers is arranged between the second partial layers of each second pair of the second partial layers.
