Abstract:
A wafer-scale module comprising:a plurality of wafers adjacently stacked, each wafer having a semiconductor layer formed thereon, with a plurality of through holes arranged circumferentially thereon and extending normal to a plane thereof, each wafer further having a plurality of optical transmission interfaces extending normal to said wafer plane and a plurality of integrated circuits formed on said semiconductor layer, said plurality of integrated circuits including a plurality of nodes, each said node being coplanar with said wafer and proximate to one of said optical transmission interfaces, said node having means for transmitting and receiving optical data to and from said plurality of integrated circuits; a plurality of optical waveguides each extending axially through one of said optical transmission interfaces normal to said corresponding wafer node; a top plate disposed on said plurality of stacked wafers, said top plate having a plurality of through holes arranged circumferentially thereon and extending normal to a plane thereof, each said top plate through hole being aligned with one said wafer through hole; a base plate disposed opposite said top plate such that said plurality of stacked wafers are sandwiched between said top plate and said base plate, said base plate including means for thermal dissipation and a plurality of through holes arranged circumferentially thereon and extending normal to a plane thereof, each said base plate through hole being aligned with one said top plate through hole and one said wafer through hole; and means for fastening said top plate to said stacked wafers and said base plate.
