Generally, methods and apparatus are disclosed for fabrication of
angle-of-incidence layers on a substrate. In one embodiment, the
angle-of-incidence layers may have either radial or circumferential tilt
symmetry, using, for example, sputtering or evaporation techniques. In
one example, an apparatus for sputtering material comprises a substrate
support member, a cathode positioned in substantially facing relationship
with respect to the substrate support member and a shutter plate. The
shutter plate is disposed between the substrate support member and the
cathode and defining an aperture for selective transmission of sputtered
articles from the cathode on the basis of a non-perpendicular trajectory
angle relative to a plane of the substrate support member.
