Claim:
1. A semiconductor assembly including: a substrate member including a first chip and a top surface; and a cap member with a first recess formed therein, the cap member including a first recess surface and a first set of rigid small scale structure(s) extending from at least a portion of the first recess surface into the first recess, with the first recess surface and the first set of rigid small scale structure(s) defining the first recess; wherein: the first set of rigid small scale structure(s) include a structure having formed therein pores, gaps and or interstitial spaces sized and shaped to facilitate gas-assisted direct liquid cooling fluid flow through the first recess; the first set of rigid small scale structure(s) are sized, shaped and located to provide for appropriate fluid flow when gas and liquid are circulated through the first recess for gas-assisted direct liquid cooling; the cap member is attached to the top surface of the substrate member at a location such that circulation of gas and liquid through the first recess cools the first chip by gas-assisted direct liquid cooling; the member cap has a plurality of channels formed therethrough, with the channels being shaped and sized to allow for gas-assisted direct liquid cooling fluid flow through the first recess.
