Abstract
A process to fabricate a fin for a heat sink includes creating an array of micro diameter holes on a substrate, and then coupling the substrate to a mold. The mold includes angular dimples such that one or more of the micro diameter holes on the substrate come into contact with the angular dimples in the mold, thereby forming an angle between the micro diameter holes and a surface of the substrate. The process further includes placing the substrate onto a plate. The plate includes micro air channels such that the micro air channels are in communication with the micro diameter holes. In another embodiment, two pieces of substrate, each with micro diameter holes and embossed micro air channels are coupled together to form a fin.
