Patent ID: 6872661

Claim:
A process for fabricating a leadless plastic chip carrier, having the steps of: depositing a photo-imageable mask on a first surface of a leadframe strip; imaging and developing said mask to define a plurality of die attach pads, at least one row of contact pads and power/ground ring intermediate said die attach pads a said contact pads; depositing plurality of layers on portions of said first surface exposed by said imaging and said developing for creating said at least one row of contact pads, said power/ground ring and said plurality of the attach pads; mounting said semi-conductor die to said die attach pads on a top surface thereof; wire bonding said semiconductor die to said contact pads; encapsulating said mask, said layers, and said die between a moulding; compound and said first surface of said leadframe strip; etching back a bottom surface of said leadframe strip for exposing said contact pads an said die attach pads; singulating said leadless plastic chip carrier from said leadframe strip.
