Patent ID: 7846775

Claim:
A method of packaging semiconductor devices comprising: generating a multiplicity of loose separated solid contacts; providing a stencil arranged with a plurality of openings formed therein, the plurality of openings configured in a spaced apart arrangement, each opening sized to accommodate the placement of one of said loose separated solid contacts; providing an adhesive carrier having an adhesive treated surface having a layer of adhesive material formed thereon; placing the previously formed multiplicity of loose separated solid contacts into the plurality of openings of the stencil to position the loose separated solid contacts in the spaced apart arrangement corresponding to a desired pattern of contacts; adhering the loose separated solid contacts arranged in the stencil onto the adhesive treated surface of the adhesive carrier, thereby adhering the multiplicity of loose separated solid contacts onto the adhesive treated surface in said desired pattern of contacts supported by the adhesive carrier; removing the stencil; mounting a plurality of dice on the desired pattern of contacts such that each die is mounted on a plurality of contacts comprising the desired pattern of contacts; wire bonding selected ones of the contacts comprising the desired pattern of contacts to associated electrical contact points of the die using wire connectors; encapsulating the dice and portions of the contacts comprising the desired pattern of contacts with an encapsulant while protecting bottom surfaces of the contacts comprising the desired pattern of contacts from exposure to said encapsulant, wherein the encapsulant flows between the contacts comprising the desired pattern of contacts thereby holding the desired pattern of contacts in place and encapsulating said wire connectors, whereby a plurality of semiconductor packages are formed.
