Abstract:
A method is provided for preparing semiconductor structure, e.g., a semiconductor on insulator structure, comprising a device layer having a smooth surface. The method provided involves smoothing a semiconductor substrate surface by making use of stress enhanced surface diffusion at elevated temperatures. The purpose of this method is to reach atomic scale surface smoothness (for example, smoothness in the range of between 1.0 and 1.5 angstroms as measured according to root mean square over a 30 um×30 um AFM measurement), which is required in advanced (sub 28 nm) CMOS device fabrication.

Claim (Index 47):
The method of  claim 37  wherein the exposed surface of the single crystal semiconductor device layer is smoothed to a root mean square surface roughness over a 30 micrometer by 30 micrometer surface region of between about 0.8 angstroms and about 1.2 angstroms.
