Lead frame for a package for a semiconductor device, semiconductor device and process for manufacturing a semiconductor device
11515240 · 2022-11-29 · ·

A lead frame for an integrated electronic device includes a die pad made of a first metallic material. A top coating layer formed by a second metallic material is arranged on a top surface of the die pad. The second metallic material has an oxidation rate lower than the first metallic material. The top coating layer leaves exposed a number of corner portions of the top surface of the die pad. A subsequent heating operation, for example occurring in connection with wirebonding, causes an oxidized layer to form on the corner portions of the top surface of the die pad at a position in contact with the top coating layer.
