Abstract: Packaging and encapsulation methods include use of a tape substrate with a mold gate that includes an aperture and a support element that extends over at least a portion of the aperture. The tape substrate may be part of a strip. A semiconductor device is secured and electrically connected to the tape substrate. The resulting assembly is placed into a cavity of a mold, and encapsulant is introduced into the cavity through the mold gate of the tape substrate. Once the encapsulant has sufficiently hardened, the package assembly may be removed from the mold, and a sprue of residual encapsulant removed therefrom. If the package assembly is carried by a strip that carries other package assemblies, it may be removed from the strip.

Abstract: A system for degating a packaged semiconductor device that includes a tape substrate includes a first element and a second element. The first element of the system is positionable adjacent to a first major surface of the packaged semiconductor device and includes a receptacle for receiving a portion of a gate of the packaged semiconductor device. A second element of the degating system is positionable adjacent to a second major surface of the packaged semiconductor device and includes a degating element alignable with the gate. The degating element is extendable through the gate to force a portion of the gate and a sprue therein into the receptacle of the first element.

Abstract: A mold gate of a tape substrate includes an aperture formed in the flexible dielectric film of the tape substrate and a support element which is carried by a surface of the flexible dielectric film. The aperture of the mold gate may be formed by die cutting or etching processes. The support element of the mold gate is substantially coplanar with conductive traces carried by the flexible dielectric film, and may be formed from the same material as the conductive traces. The support element of the mold gate may be fabricated by patterning a conductive film and formed at substantially the same time as the conductive traces of the tape substrate are formed. Packaging methods and degating methods that include use of the tape substrate are also disclosed.
