Abstract:
A gas distribution plate for a plasma reactor has a dielectric front plate and a dielectric back plate bonded together, with gas injection orifices extending through the front plate and gas supply channels in the surface of front plate facing the back plate. The back plate is joined to a heat reflective plate, or the back plate itself is formed of a heat reflective material, such as Beryllium Oxide.
Abstract:
A microwave antenna includes a first spiral conduit having a first conduit end, first plural ports in a floor of the first spiral conduit spaced apart along the length of the first spiral conduit; an axial conduit coupled to a rotatable stage; and a distributor waveguide comprising an input coupled to the axial conduit and a first output coupled to the first conduit end.
Abstract:
A deposited amorphous carbon film includes at least 95% carbon. A percentage of sp3 carbon-carbon bonds present in the amorphous carbon film exceeds 30%, and a hydrogen content of the amorphous carbon film is less than 5%. A process of depositing amorphous carbon on a workpiece includes positioning the workpiece within a process chamber and positioning a magnetron assembly adjacent to the process chamber. The magnetron assembly projects a magnetic field into the process chamber. The method further includes providing a carbon target such that the magnetic field extends through the carbon target toward the workpiece. The method further includes providing a source gas to the process chamber, and providing pulses of DC power to a plasma formed from the source gas within the process chamber. The pulses of DC power are supplied in pulses of 40 microseconds or less, that repeat at a frequency of at least 4 kHz.
