Abstract
We have investigated the electrical and physical properties of high-temperature (1300, 1400 oC) grown dry oxide with or without post oxidation annealing (POA) in nitric oxide (NO) gas. A significant reduction in interface-trap density (Dit) has been observed in 1300 oC-grown dry oxide with or without NO POA if compared with the Dit of 1400 oC-grown dry oxide. The reason for this has been explained in this paper.
