Abstract:
A method for producing an electric device with a multi-layer contact is disclosed. In an embodiment, a method includes providing a carrier, the carrier having a metallic layer disposed on its surface, providing a semiconductor substrate, forming a layer stack on the semiconductor substrate and attaching the layer stack of the semiconductor substrate to the metallic layer of the carrier so that an intermetallic phase is formed between the metallic layer and the solder layer.

Claim (Index 7):
A method for fabricating an electronic device, the method comprising:\n providing a semiconductor substrate; directly depositing an electrical contact layer on the semiconductor substrate, the electrical contact layer being a single elemental Al layer; directly depositing a functional layer on the electrical contact layer, the functional layer comprising Ti or an alloy containing Ti; directly depositing an adhesion layer onto the functional layer, the adhesion layer comprising Ni; directly depositing a solder layer on the adhesion layer, the solder layer being a single element Sn layer; providing a carrier, the carrier having a metallic layer disposed on its surface, wherein the metallic layer comprises Ni or NiNiP; and bonding the semiconductor substrate on the carrier so that an a homogenous layer comprising an intermetallic phase of Sn and Ni is formed based on isothermal solidification at a soldering temperature.
