Patent ID: 7538425

Claim:
A semiconductor package, comprising: a circuit board having inlet and outlet fluid conduits formed therein; a first substrate supported on said circuit board; a semiconductor device including a semiconducting silicon chip supported on a first major surface of said substrate opposite said circuit board and defining at least one conductor pad thereon; a set of micro-channels form in said semiconducting silicon chip, said micro-channels opening toward said first major surface; and a fluid manifold formed in said semiconducting silicon chip in circuit with said set of micro-channels, said first substrate including a fluid inlet coupled to said fluid manifold at a first end of said set of micro-channels for delivering coolant fluid from said inlet conduit to said micro-channels, and a fluid outlet coupled to said fluid manifold at a second end of said set of micro-channels opposite said first end for exhausting said coolant fluid from said micro-channels to said outlet conduit, said fluid inlet extending through said substrate and coupled with said circuit board inlet fluid conduit and said fluid outlet extending through said substrate and coupled with said circuit board outlet fluid conduit; wherein said first substrate is supported on said circuit board to which terminals of said semiconductor device are attached, and wherein said fluid inlet comprises a series of openings formed in said substrate and opening into said fluid manifold, said semiconductor package further comprising a plate joined to a second major surface of said first substrate opposite said first major surface with an intervening metallization layer defining a fluid plenum that couples said fluid conduit to said series of openings.
