Abstract

A method of forming an on-chip heat sink includes forming a device on a substrate. The method also includes forming a plurality of insulator layers over the device. The method further includes forming a heat sink in at least one of the plurality of insulator layers and proximate to the device. The heat sink includes a reservoir of phase change material having a melting point temperature that is less than an upper limit of a design operating temperature of the chip.
