Abstract:
A leadframe for a semiconductor package is disclosed including electrical leads which extend from one side of the leadframe to an opposite side of the leadframe, where electrical connection may be made with the semiconductor die at the second side of the leadframe. The semiconductor die may be supported on the leads extending across the leadframe. The package may further include a spacer layer affixed to the electrical leads to fortify the semiconductor package and to prevent exposure of the electrical leads during the molding of the package.
