Abstract: Enhanced thermal energy transfer systems for semiconductor packages are provided. A thermally conductive member is disposed in the interstitial space between an upper surface of a semiconductor package and a lower surface of a thermal member. The thermally conductive member is disposed above a first portion of the upper surface of the semiconductor package having a relatively higher thermal energy output when the semiconductor package is operating. A thermal interface material is disposed in the interstitial space and a force applied to the thermal member. The thermally conductive member forms a relatively higher pressure region above the first portion of the semiconductor package and a relatively lower pressure region in other portions of the semiconductor package remote from the thermally conductive member. The increased pressure region proximate the thermally conductive member beneficially enhances the flow of thermal energy from the first portion of the semiconductor package to the thermal member.
