SEMICONDUCTOR DEVICES ON DIFFUSION BARRIER COATED SUBSTRATES AND METHODS OF MAKING THE SAME

摘要

Semiconductor devices on a diffusion barrier coated metal substrates, and methods of making the same are disclosed. The semiconductor devices include a metal substrate, a diffusion barrier layer on the metal substrate, an insulator layer on the diffusion barrier layer, and a semiconductor layer on the insulator layer. The method includes forming a diffusion barrier layer on the metal substrate, forming an insulator layer on the diffusion barrier layer; and forming a semiconductor layer on the insulator layer. Such diffusion barrier coated substrates prevent diffusion of metal atoms from the metal substrate into a semiconductor device formed thereon.
