Thin film contacts are becoming increasingly important in the miniaturization of electronic devices. This paper considers the spreading resistance of a microscopic contact of size a ("a- spot") on a thin film. The effect of the film thickness h on the spreading resistance is evaluated over a large range of the aspect ratio a/h, for both Cartesian and cylindrical geometries. In the limit...
Contact problems account for 40 percent of all electrical/electronic failures, ranging from small scale consumer electronic devices to large scale military and aerospace systems. This paper summarizes recent development on the theory of bulk contact and thin-film contacts, whose contact members may possess vastly different electrical resistivities. Current crowding at the rim of an electrode, scaling...
