The high temperatures also burn off submicron organic particles.
The top images show alternating Cu and Fe growth rings on the submicron scale indicating a low oxygen environment.
The technique can be used to analyze three-dimensional surface features with very high spatial resolution in a submicron size range.

He is now responsible for reliability modeling and analysis of deep submicron devices covering oxide integrity, hot carrier, electromigration and ESD.
