Abstract:
1. A semiconductor device assembly comprising: a semiconductor device having an active surface having a plurality of bond pads thereon; a lead frame having a portion thereof having an attaching surface for attaching the portion of the lead frame to a portion of the active surface of the semiconductor device, the portion of the lead frame including at least a plurality of lead fingers adhesively secured solely and directly attached by an adhesive to the portion of the active surface of the semiconductor device; an indexing feature on or adjacent to an outer periphery of the lead frame, the indexing feature including a plurality of perforations and configured such that the lead frame, or an assembly corresponding thereto, can be spatially advanced by engagement of an advancing means with the indexing feature; and an epoxy adhesive attaching the portion of the lead frame to the portion of the active surface of the semiconductor device, the epoxy adhesive having a cure time of less than about one second for an amount of about one milligram of epoxy adhesive applied directly on the attaching surface of the lead frame for a semiconductor device urged into the epoxy adhesive by a block heated at a temperature in a range of about 200° C. to about 225° C.
