A method of growing single crystal diamond assisted by polycrystalline diamond growth to enhance dimensions and quality of the single crystal diamond includes thermally mating a diamond seed on a top surface of a substrate holder providing a growth surface for a combination of single crystal diamond and polycrystalline diamond. A predetermined temperature difference between the diamond seed and the substrate holder during processing along with the plasma process conditions causes a single crystal diamond growth rate to be different from a polycrystalline growth rate by a predetermined amount. Process gasses are introduced, and a plasma is formed to grow both single crystal diamond and polycrystalline diamond on the growth surface so that the polycrystalline diamond grown adjacent to the single crystal diamond shields side surfaces of the growing single crystal diamond, thereby improving growth quality across the growing single crystal diamond.

A plasma processing apparatus includes a toroidal-shape plasma vessel comprising a process chamber. A magnetic core surrounds a portion of the toroidal-shape plasma vessel. An RF power supply having an output that is electrically connected to the magnetic core energizes the magnetic core, thereby forming a toroidal plasma loop discharge in the plasma chamber. A workpiece holder is positioned in the toroidal-shape plasma vessel and includes at least one face. A plasma guiding structure is shaped and dimensioned so as to constrain a section of plasma in the toroidal plasma loop to travel substantially perpendicular to a normal to the at least one face.

A manufacturing equipment digital interface includes a shared Small Computer Standard Interface (SCSI) connector that is electrically connected to a manufacturing equipment SCSI bus. A plurality of SCSI-to-target-memory bridges is electrically connected to the shared SCSI connector. The plurality of SCSI-to-target-memory bridges interfaces the shared SCSI connector to a plurality of target memory devices. A drive controller includes a memory buffer that provides temporary storage of the information being transferred from the manufacturing equipment SCSI bus to the plurality of target memory devices. Also, the drive controller includes a SCSI-to-target-memory bridge arbitrator that controls the transfers of information from the manufacturing equipment SCSI bus to the target memory device. A network interface is electrically connected to the drive controller.

A method of CVD plasma processing for depositing at least one of diamond, diamond-like-carbon, or graphene includes forming a vacuum chamber comprising a conduit and a process chamber. A gas is introduced into the vacuum chamber. An RF electromagnetic field is applied to a magnetic core to form a toroidal plasma loop discharge in the vacuum chamber. A workpiece is positioned in the process chamber for plasma processing at a distance from a hot plasma core to a surface of the workpiece that is in a range from 0.1 cm to 5 cm. A gas comprising hydrogen is introduced to the workpiece so that the toroidal plasma loop discharge generates atomic hydrogen.

A CRT light pen emulating interface with power save and remote access for flat panel displays includes a pen flat panel display that indicates at least one of a user action with a light pen switch or other device and a presence of a light pen emulating object positioned on or proximate to a display surface of the electromagnetic pen flat panel display. A light pen emulating object is positioned proximate to the electromagnetic pen flat panel display. A processor generates a light pen emulation signal comprising position data for the light pen emulating object relative to the display surface of the electromagnetic flat panel display. A light pen CRT electronic interface converts the position data for the light pen emulating object into a corresponding signal that is comparable to a signal generated by a CRT light pen viewing a scanning dot on the CRT screen.
