Method of making an electronic device cooling system

摘要

A method is provided. The method includes forming a conductive layer on an inner surface of a substrate (12) and providing a sacrificial layer (36) over the conductive layer. The method includes forming a plurality of channels in the sacrificial layer (36) and plating the sacrificial layer to substantially fill the plurality of channels with a plating material comprising conducting material. The method also includes etching the sacrificial layer (36) to form a conducting structure having fins where conducting material remains separated by microchannels where the sacrificial layer (36) is etched.
