Abstract
A magnetron sputtering apparatus for depositing material onto a substrate, comprises: a chamber comprising a substrate support and a target; a plasma production device configured to produce a plasma within the chamber suitable for sputtering material from the target onto the substrate; and a thermally conductive grid comprising a plurality of cells. Each cell comprises an aperture and the ratio of the height of the cells to the width of the apertures is less than 1.0. The grid is disposed between the substrate support and the target and is substantially parallel to the target. The upper surface of the substrate support is positioned at a distance of 75 mm or less from the lower surface of the target.
