Abstract: An apparatus and method provide deposition on a surface by angled sputtering using a collimation grid having angled vanes which limit the distribution of trajectories of particles in at least one coordinate direction around a central axis oriented at an angle of less than 90.degree. to said surface; resulting in improved uniformity of deposition and/or selective favoring of deposition on surfaces at a high angle to the deposition surface (e.g. sidewalls). Substantially parallel orientation and uniform spacing of the sputtering target and deposition surface provides good uniformity of results over the deposition surface. The angled trajectories of sputtered particles provides improved deposition on sides of upstanding mandrel features and filling of recessed features of high aspect ratio, especially when the collimation grid is rotated about an axis generally perpendicular to the deposition surface.
