Abstract: A system comprises a processing chamber for maintaining a hydrogen plasma at low pressure. The processing chamber has a long, wide, thin geometry to favor deposition of thin-film silicon on sheet substrates over the chamber walls. The sheet substrates are moved through between ends. A pair of opposing radio frequency electrodes above and below the workpieces are electrically driven hard to generate a flat, pancaked plasma cloud in the middle spaces of the processing chamber. A collinear series of gas injector jets pointed slightly up on a silane-jet manifold introduce 100% silane gas at high velocity from the side in order to roll the plasma cloud in a coaxial vortex. A second such silane-jet manifold is placed on the opposite side and pointed slightly down to further help roll the plasma and maintain a narrow band of silane concentration. A silane-concentration monitor observes the relative amplitudes of the spectral signatures of the silane and the hydrogen constituents in the roll-vortex plasma and outputs a process control feedback signal that is used to keep the silane in hydrogen concentration at about 6-7%.

An example method to manufacture an organic photoconductor involves applying a liquid solution to a surface of a cylindrically-shaped substrate while rotating the substrate about its axis, the substrate comprising a surface layer and the liquid solution comprising a matrix polymer species and a dopant species dissolved in a solvent. The example method further involves rotating the substrate while the solvent evaporates to provide a substantially evenly distributed seamless residue film comprising the matrix polymer species and the dopant species, and cross-linking the matrix polymer species of the residue film.
