Abstract

Abstract A process for making a semiconductor device and the resulting device having standardized die-to-substrate bonding locations are herein disclosed. The semiconductor die provides a standardized ball grid or other array of a particular size, pitch and pattern such that as the size, configuration or bond pad arrangement of the die changes, a standard substrate (the term including leadframes) having a similarly standardized array of terminals or trace ends can be employed to form a semiconductor device. It is also contemplated that dies having markedly different circuitry but a common array pattern may be employed with the same substrate or other carrier.
