    • A plasma reactor for processing a semiconductor workpiece includes a reactor chamber and a set of plural parallel ion shower grids that divide the chamber into an upper ion generation region and a lower reactor region, each of the ion shower grids having plural orifices in mutual registration from grid to grid, each orifice being oriented in a non-parallel direction relative to a surface plane of the respective ion shower grid. A workpiece support in the process region faces the lowermost one of the ion shower grids. A reactive species source furnishes into the ion generation region a chemical vapor deposition precursor species. The reactor further includes a vacuum pump coupled to the reactor region, a plasma source power applicator for generating a plasma in the ion generation region and a grid potential source coupled to the set of ion shower grids. The orifices through at least some of the ion shower grids have an aspect ratio sufficient to limit ion trajectories in the reactor region to a narrow angular range about the non-parallel direction, and a resistance to gas flow sufficient to support a pressure drop between the ion generation and reactor regions of about at least a factor of 4. The grid potential source can be capable of applying different voltages to different ones of the grids.

    • A chemical vapor deposition process is carried out in a reactor chamber with an ion shower grid that divides the chamber into an upper ion generation region and a lower process region, the ion shower grid having plural orifices oriented in a non-parallel direction relative to a surface plane of the ion shower grid. A workpiece is placed in the process region facing the ion shower grid, the workpiece having a workpiece surface generally facing the surface plane of the ion shower grid. A gas mixture is furnished comprising deposition precursor species into the ion generation region and the process region is evacuated at an evacuation rate sufficient to create a pressure drop across the ion shower grid from the ion generation region to the process region whereby the pressure in the ion generation region is at least several times the pressure in the process region. A layer of material of a desired thickness is deposited on the workpiece by: (a) applying plasma source power to generate a plasma of the deposition precursor species in the ion generation region, and (b) applying a grid potential to the ion shower grid to create a flux of ions from the plasma through the grid and into the process region.
