Abstract
A switch includes a heater layer, a phase change material (PCM) layer on the heater layer, and a spreader layer formed in proximity to the PCM layer and including a central region with a first thermal conductivity and an edge region with a second thermal conductivity different than the first thermal conductivity. A method of forming a switch includes forming a heater layer, forming a phase change material (PCM) layer on the heater layer, and forming a spreader layer in proximity to the PCM layer, such that the spreader layer includes a central region with a first thermal conductivity and an edge region with a second thermal conductivity different than the first thermal conductivity.
