Abstract:
A method of making a semiconductor chip package, the method comprising:providing a semiconductor chip having an active device therein; encapsulating the semiconductor chip in a compound; forming a surface on said compound; and forming a first region on the surface of the compound, said first region: being integral with the compound; being offset from said surface on said compound; and making a conforming fit with a second region, said second region being offset from a surface of an alignment fixture, whereby the compound is held in contact engagement with the alignment fixture at an interface that is formed by at least one of: a concave surface in the compound encapsulating said semiconductor chip and a convex surface of the alignment fixture; and a convex surface in the compound encapsulating said semiconductor chip and a concave surface of the alignment fixture.
