The crystallization of thin amorphous TaOx films formed by d.c. reactive sputtering was investigated at temperatures from 500–700 °C. The films remained amorphous for times up to 100 h at 500 °C. The formation of discrete, single crystallites of

The α 2 +β alloy Ti-24 at%Al-11at%Nb was evaluated for mechanical properties in the as-received, mill annealed condition (nearly equiaxed) and in the β annealed condition (basketweave). The as-received condition had a moderately strong basal trans

The effects of microstructure on electromigration behavior were evaluated in three nominally 1 μm thick pure aluminum films, which were tested at temperatures from 423 to 523 K. The three Al films had essentially the same grain structure but differe

Leading-edge packaging applications are demanding some combination of greater interconnect density, smaller size, higher system performance, and lower cost. The elimination of the chip-level package in favor of the direct attachment of chips to a sub

The effects of thin Ti, TiN, or Ti/TiN underlayers on the development of the crystallographic texture and the grain structure are explored. Metal layers ∼0.5 μm in thickness of Al‐0.5Cu or of Cu are deposited on these underlayers and on amorphou

Thin films are important in a variety of applications, including optical, magnetic,and electronic devices. The origin of microstructure in films formed by physical vapor deposition depends primarily on the homologous deposition temperature, which det

Textures in materials have been studied extensively since the 1930s following the pioneering work of Wassermann.1,2 The modern era of texture measurement started in 1949 with the development of the x-ray pole figure technique for texture measurement

The effects of isothermal aging on the microstructure and mechanical behavior of Sn-Bi/Cu solder joints are reported. Lap shear solder joints of eutectic Sn-Bi solder were aged for 3 to 30 days at 80°C and then loaded to failure in shear. Changes in
