Definition

A heat spreader is a thermally conductive element that distributes heat away from a concentrated semiconductor heat source over a larger area.

Application

In advanced packages and power/RF electronics, heat spreaders reduce local hot spots and improve heat transfer from devices such as AI accelerators, GaN HEMTs, and SiC power modules.
