The relationship between the structural property and the electrical characteristics of thin SiO2 below 4 nm is investigated. The structural `strained-layer' near SiO2/Si interface is confirmed to affect strongly the TDDB (Time Dependent Dielectric Breakdown) lifetime of the thin gate oxides. The increase of the built-in compressive strain analyzed by the XPS (X-ray Photoelectron Spectroscopy)-based technique is experimentally found to decrease the TDDB lifetime.
