  • Patent number: 10325838
    Abstract: A method of fabricating a semiconductor device is disclosed. In one aspect, the method includes placing a first semiconductor chip on a carrier with the first main surface of the first semiconductor chip facing the carrier. A first layer of soft solder material is provided between the first main surface and the carrier. Heat is applied during placing so that a temperature at the first layer of soft solder material is equal to or higher than a melting temperature of the first layer of soft solder material. A second layer of soft solder material is provided between the first contact area and the second main surface. Heat is applied during placing so that a temperature at the second layer of soft solder material is equal to or higher than a melting temperature of the second layer of soft solder material. The first and second layers of soft solder material are cooled to solidify the soft solder materials.
