Abstract: A method includes placing a substrate on a first curved surface of a first bending tool, using a second bending tool with a second surface to apply pressure to the substrate, thereby pressing the substrate onto the first curved surface and bending the substrate, and removing the bended substrate from the first bending tool.

Abstract: A semiconductor chip includes a semiconductor body having a bottom side and a top side opposite the bottom side, and passivation arranged on the top side. The semiconductor chip is positioned on the carrier by picking the semiconductor chip and placing the semiconductor chip on the carrier, and pressing the semiconductor chip onto the carrier by a pressing force in a pressing direction, such that the pressing force acts on the semiconductor chip only above one or more continuous chip metallization sections arranged on the top side. Each of the one or more continuous chip metallization sections includes an annularly closed edge section which has a minimum width of more than zero in each direction perpendicular to the pressing direction. The pressing force does not act on the semiconductor chip above any of the edge sections.

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.

Abstract: A sintered connection is formed by pressing a semiconductor die against a substrate with a dried sintering material interposed between the substrate and the semiconductor die, the dried sintering material having sintering particles and a solvent. The substrate is heated to a temperature below a sintering temperature of the dried sintering material while the semiconductor die is pressed against the substrate to form local sinter connections between adjacent ones of the sintering particles. The local sinter connections collectively provide a stable joint that fixes the semiconductor die to the substrate prior to sintering. A sintered connection is then formed between the semiconductor die and the substrate from the dried sintering material, after the stable joint is formed.

Abstract: A semiconductor device includes a substrate and a first sintered silver layer on the substrate. The semiconductor device includes a first semiconductor chip and a first diffusion soldered layer coupling the first semiconductor chip to the first sintered silver layer.
