ABSTRACT:
A brazed leaded package is provided having buried brazed areas thereby eliminating the need of subsequent protective plating of the brazed areas. The package has a heat conductive support which supports a plurality of leads. The distal end of the leads terminate on the top of the heat conductive support in a braze pad to which are brazed formed leads for providing interface connection to a semiconductor integrated circuit contained within the package. The package can be sealed by using a solid ceramic cover having a glazed glass on its bottom side which is heated up to reflow and provide the seal.
