Abstract

The reaction of molecular hydrogen with Pb defects at the (111) Si/SiO2 interface has been studied using a remote radio frequency (RF) probe to continuously monitor the rate of removal of electrically active defects. The kinetic parameters calculated from these experiments are compared with the earlier work of Brower and Stesmans. Although the data confirms the non-exponential nature of the reaction reported by Stesmans the activation energy of the process is found to be somewhat different.
