Patent ID: 7724527

Claim:
A method of improving thermal dissipation from a module assembly, the method comprising: attaching a first side of at least one chip to a single chip carrier or multi chip carrier, the at least one chip having a second side opposite of the first side; grinding the second side of the at least one chip to a desired surface profile; selectively thinning a portion of the second side beyond the desired surface profile; applying a heat transfer medium on at least one of a heat sink, including a pedestal, and the second side of the at least one chip; and disposing the heat sink on the second side of the at least one chip with the pedestal positioned proximate to the selectively thinned portion and with the heat transfer medium therebetween defining a gap between the heat sink and the second side of the at least one chip, wherein the gap is controlled to improve heat transfer from the second side of the at least one chip to the heat sink.
