  • Patent number: 9099454
    Abstract: A semiconductor package is manufactured by providing a semiconductor die with a terminal at a first side of the die, providing a material coupled to the die at an opposing second side of the die and embedding the die in a molding compound so that the die is covered by the molding compound on all sides except the first side. The molding compound is thinned at a side of the molding compound adjacent the second side of the die, to expose the material at the second side of the die without exposing the second side of the die. An electrical connection is formed to the terminal at the first side of the die. In the case of a transistor die, the terminal can be a source terminal and the transistor die can be attached source-down to a metal block such as a die paddle of a lead frame.

  • Patent number: 9082759
    Abstract: In accordance with an embodiment of the present invention, a semiconductor package includes a die paddle, and an encapsulant disposed around the die paddle. The semiconductor package has a first sidewall and a second sidewall. The second sidewall is perpendicular to the first sidewall. The first sidewall and the second sidewall define a corner region. A tie bar is disposed within the encapsulant. The tie bar couples the die paddle and extends away from the die paddle. A dummy lead is disposed in the corner region. The dummy lead is not electrically coupled to another electrically conductive component within the semiconductor package. The distance between the dummy lead and the tie bar is less than a shortest distance between the tie bar and other leads or other tie bars in the semiconductor package.
