Abstract
Lateral heating processing of SiO 2/Si samples can reduce the tunneling current of SiO 2 by 5 orders of magnitude with very good reproducibility. There is a strong correlation between the flatband voltage shift of metal-oxide-semiconductor capacitors and the tunneling current reduction. Analysis of the flatband voltage shift suggests that origin of the tunneling current reduction after lateral heating is caused by the structure change of Si, most likely tensor strained Si, near the SiO 2/Si interface.
