Abstract:
1. A method for applying redistribution circuitry for a semiconductor device assembly to an active surface of a semiconductor die, comprising: applying a first circuitry-bearing tape segment to a first region of the active surface of the semiconductor die, the first circuitry-bearing tape segment having an electrically insulating layer having a first surface bearing a first circuit portion comprising a first plurality of discrete conductive traces and an opposing second surface, and a support layer adjacent the opposing second surface of the electrically insulating layer; and applying a second circuitry-bearing tape segment to a second region of the active surface of the semiconductor die, the second circuitry-bearing tape segment having a electrically insulating layer having first surface bearing a second circuit portion comprising a second plurality of discrete conductive traces and an opposing second surface, and a support layer adjacent the opposing second surface of the electrically insulating layer, and wherein the first and second circuit portions together form a redistributed electrical connection pattern for the semiconductor device assembly.
