  • Patent number: 11450794
    Abstract: A carrier and a component are disclosed. In an embodiment a component includes a semiconductor chip including a substrate and a semiconductor body arranged thereon and a metallic carrier having a coefficient of thermal expansion which is at least 1.5 times greater than a coefficient of thermal expansion of the substrate or of the semiconductor chip, wherein the semiconductor chip is attached to a mounting surface of the metallic carrier by a connection layer such that the connection layer is located between the semiconductor chip and a buffer layer and adjoins a rear side of the semiconductor chip, wherein the buffer layer has a yield stress which is at least 10 MPa and at most 300 MPa, and wherein the substrate of the semiconductor chip and the metallic carrier of the component have a higher yield stress than the buffer layer.

  • Patent number: 11183621
    Abstract: A component may include a semiconductor chip, a buffer layer, a connecting layer, and a metal carrier. The semiconductor chip may include a substrate and a semiconductor body arranged thereon. The metal carrier may have a thermal expansion coefficient at least 1.5 times as great as a thermal expansion coefficient of the substrate or of the semiconductor chip. The chip may be fastened on the metal carrier by the connecting layer, and the buffer layer may have a yield stress ranging from 10 MPa. The buffer layer may have a thickness ranging from 2 um to 10 um and adjoin the chip. The substrate and the metal carrier may have a higher yield strength than the buffer layer.
