Abstract

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