Abstract:
A method of fabricating a semiconductor die assembly having at least one substrate and at least one semiconductor die attached to said substrate for substantially preventing filler particles in said material from residing between the semiconductor die and the substrate from the encapsulation of the semiconductor die comprising:providing said at least one semiconductor substrate having a first surface and a second surface, said semiconductor substrate including at least one opening defined through said semiconductor substrate between said first surface of said semiconductor substrate and said second surface of said semiconductor substrate; providing said at least one semiconductor die having an active surface having at least one electrical connection area disposed on said active surface; disposing at least one adhesive tape between said semiconductor die active surface and said semiconductor substrate first surface for attaching said semiconductor die to said at least one semiconductor substrate, a width of said at least one adhesive tape extending from not less than an edge of said at least one semiconductor die to at least an edge of said at least one opening of said semiconductor substrate; and aligning said at least one semiconductor die having said at least one electrical connection area oriented with said at least one semiconductor substrate opening having said at least one adhesive tape extending from at least an edge of said semiconductor die to at least an edge of said opening of said semiconductor substrate for filling an area located between an edge of said semiconductor die and an edge of said opening in said semiconductor substrate for substantially preventing filler particles in said encapsulant material from residing between the semiconductor die and the substrate from the encapsulation of the semiconductor die preventing damage to at least one of said active surface of said semiconductor die and said first surface of said semiconductor substrate.
