Popis: Basal crystallographic orientation and semiamorphous films which are nominally aluminum nitride were grown by reactive sputter deposition on silicon substrates and characterized by x‐ray photoelectron spectroscopy and Auger electron spectroscopy. The binding energy of the aluminum 2p, nitrogen 1s, and oxygen 1s core electrons and the kinetic energy of the aluminum LVV and KLL Auger transitions indicate that all films contain a component which is chemically identifiable as AlN. The films contain oxygen as a major impurity. The difference in the manner in which oxygen is incorporated into the films, determined by these two spectroscopic techniques, is discussed and related to deposition conditions.
