The preferred crystallographic orientation, or texture, of aluminum films deposited on oxidized silicon by evaporation and by partially ionized beam (PIB) deposition is studied. Texture is quantified by the xhyphen;ray diffraction pole figure technique. The pole figures reveal important details of the crystallite distribution not quantifiable by simply taking the 2thgr; scan. It is found that the films deposited by the PIB technique possess a very strong lcub;111rcub; fiber texture whose strength can be controlled by deposition conditions. Correlation between the strength of the texture and the electromigration lifetime is discussed.
