摘要： A plasma immersion ion implantation process for implanting a selected species at a desired ion implantation depth profile in a workpiece is carried out in a reactor chamber having a set of plural parallel ion shower grids that divide the chamber into an upper ion generation region and a lower process region, each of the ion shower grids having plural orifices in mutual registration from grid to grid, the plural orifices oriented in a non-parallel direction relative to a surface plane of the respective ion shower grid. The process includes placing a workpiece in the process region, the workpiece having a workpiece surface generally facing the surface plane of the closest one of the plural ion shower grids, and furnishing the selected species into the ion generation region. The process further includes evacuating the process region, and applying plasma source power to generate a plasma of the selected species in the ion generation region. The process also includes applying successive grid potentials to successive ones of the grids and applying a bias potential to the workpiece. The combination of the grid and bias potentials corresponds to the desired ion implantation depth profile in the workpiece.

摘要： A process for conformally doping through the vertical and horizontal surfaces of a 3-dimensional vertical transistor in a semiconductor-on-insulator structure employs an RF oscillating torroidal plasma current to perform either conformal ion implantation, or conformal deposition of a dopant-containing film which can then be heated to drive the dopants into the transistor. Some embodiments employ both conformal ion implantation and conformal deposition of dopant containing films, and in those embodiments in which the dopant containing film is a pure dopant, the ion implantation and film deposition can be performed simultaneously.

摘要： A chemical vapor deposition process is carried out in a reactor chamber having a set of plural parallel ion shower grids that divide the chamber into an upper ion generation region and a lower process 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 is placed in the process region, so that a workpiece surface of the workpiece is generally facing a surface plane of the nearest one of the ion shower grids, and a gas mixture comprising a deposition precursor species is furnished into the ion generation region. The process region is evacuated at an evacuation rate sufficient to create a pressure drop across the plural ion shower grids between the ion generation and process regions whereby the pressure in the ion generation region is several times the pressure in the process region. The process further includes applying plasma source power to generate a plasma of the deposition precursor species in the ion generation region and applying successive grid potentials to successive ones of the grids.

摘要： In a plasma reactor chamber a ceiling electrode and a workpiece support electrode, respective RF power sources of respective VHF frequencies f1 and f2 are coupled to either respective ones of the electrodes or to a common one of the electrodes, where f1 is sufficiently high to produce a center-high non-uniform plasma ion distribution and f2 is sufficiently low to produce a center-low non-uniform plasma ion distribution. Respective center ground return paths are provided for RF current passing directly between the ceiling electrode and the workpiece support electrode for the frequencies f1 and f2, and an edge ground return path is provided for each of the frequencies f1 and f2. The impedance of at least one of the ground return paths is adjusted so as to control the uniformity of the plasma ion density distribution.
