【Abstract】 Atomic layer deposition (ALD) is a new method for preparing films,which has the ability to control film thickness and composition accurately.Because films are deposited layer by layer,ALD has a lot of advantages,such as large area uniformity,excellent conformality.We review the mechanism and application of ALD to deposit metal oxide films in this paper.It has been noticed that ALD has more and more important potential application in high-k materials for MOSFET gate dielectrics.更多还原
