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 5):
The method of  claim 1  wherein a layer of silicon dioxide is deposited on the front surface of the single crystal semiconductor handle wafer simultaneously with deposition of the layer of silicon dioxide on the back surface of the single crystal semiconductor handle wafer, and the method further comprises removing the layer of silicon dioxide deposited on the front surface of the single crystal semiconductor handle wafer prior to the bonding step.
