Abstract:
1. A process for fabricating a leadless plastic chip carrier, comprising: partially etching at least a first surface of a leadframe strip to partially define a die attach pad, a plurality of contact pads disposed around said die attach pad, and a plurality of bond fingers intermediate said die attach pad and said contact pads; laminating a metal strip to the first surface of said leadframe strip; selectively etching a second surface of said leadframe strip opposite to said first surface such that portions of the leadframe strip are removed to define a remainder of said die attach pad, said plurality of contact pads, said plurality of bond fingers and circuitry between ones of said bond fingers and ones said contact pads; mounting a semiconductor die to said die attach pad; wire bonding said semiconductor die to ones of said bond fingers; encapsulating said second surface of said leadframe strip, said semiconductor die and said wire bonds in a molding material; removing said metal strip from said first surface of said leadframe strip; and singulating said leadless plastic chip carrier from a remainder of said leadframe strip.
