    Abstract: This invention relates to a gas delivery device for use in low pressure Atomic Layer Deposition at a substrate location. The device includes a first generally elongating injector (21) for supplying process gas to a process zone (22). A first exhaust zone (23) circumjacent the process zone (22); and a further injector (25) circumjacent the first exhaust zone for supplying purge or inert gas at outlet (26) surrounding the process zone (22, 24) for facing the location circumjacent the outlet to define at least a partial gas seal.

    Abstract: A method is for plasma etching elongate features in a generally planar workpiece of a type located in a chamber. The method includes etching a test workpiece in a flat configuration in the chamber, determining the respective angle of a longitudinal portion of the features relative to an axis passing orthogonally through the workpiece, and determining the curvature of the workpiece, which would have been required to reduce the angles, at least over a central portion of the workpiece, substantially to 0°. The method further includes processing a further workpiece of the same type whilst it is curved with the determined curvature.
