Abstract
The lateral oxidation of AlAs is becoming an important processing tool , but has proven difficult to control. A method is presented to achiev e lithographic control of the lateral oxidation process. The technique uses impurity induced layer disordering in buried, heavily Si-doped l ayers to locally change the oxidation rate of an AlAs layer. Several t ypes of capping conditions during the anneal are discussed.
