Heat sinking element and method of treating a heat sinking element

摘要

A heat sinking element and a method of treating a heat sinking element are provided. The heat sinking element includes a metal substrate. The metal substrate is mainly composed of aluminium. A surface of the metal substrate has a plurality of micro-nano holes and a diameter of the micro-nano holes is smaller than 300 nm. The method of treating a heat sinking element includes performing an oxidation process and an etching process on the metal substrate so as to form the plurality of micro-nano holes.
