Abstract:
An integrated multiple-substrate-on-chip-module (MSOCM) assembly comprising:a chip-size package (CSP)-ready MSOCM board having a top surface and a bottom surface, said CSP-ready MSOCM board includes a plurality of board bonding-wire windows opened in said MSOCM board and said CSP-ready MSOCM board further includes a plurality of board-bonding-pads disposed on said top surface of said CSP-ready MSOCM board near said bonding-wire window;an adhesive layer disposed beneath said CSP-ready MSOCM board also having a plurality of adhesive-layer bonding wire windows corresponding to and aligned with said board bonding wire windows on said MSOCM board;a plurality of integrated circuit (IC) chips mounted onto said adhesive layer under said bottom surface of said CSP-ready MSOCM board with each of said IC chips provided with a plurality of chip bonding pads facing an open space defined by said board bonding-wire windows;a plurality of bonding wires disposed in said space defined by said board bonding-wire windows and adhesive-layer bonding-wire windows and interconnected between each of said chip bonding pads and a corresponding board bonding pad disposed on said top surface of said CSP-ready MSOCM board; anda CSP-ready land-grid array comprising a plurality of land-grid contact pads disposed on said top surface of said CSP-ready MSOCM board wherein said plurality of land-grid contact pads are arranged to have a standard CSP-footprint of said IC chips whereby each of said IC chips mounted onto said CSP-ready MSOCM board is provided to be separated into an individual CSP package.
