Abstract
A method of passivating semiconductor devices including the steps of providing a semiconductor device having a surface of semiconductor material to be passivated, exposing the surface of semiconductor material to deep ultra-violet (DUV) radiation in an ambiance including oxygen so as to form a layer of oxide on the surface of semiconductor material, and forming a layer of passivation material on the layer of oxide. The DUV oxide forms a different interface with the semiconductor material which significantly improves operating characteristics of the semiconductor device.
