Look up the Massoud Model on Google. It was devised by Hisham Massoud, now Professor of EE of Duke, but who wrote a Science Citation classic paper on this topic while doing experiments relative to his PhD at IBM Yorktown. There are online calculators which include it. --- Albert K. Henning, PhD Director of MEMS Technology NanoInk, Inc. 215 E.

Can someone suggest any literature for thin oxide growth, say less than 25 nm? Thanks in advance. A. Ravi Sankar
