摘要： A capacity control system for a variable capacity refrigerant compressor includes an internal bleed passage coupling a crankcase chamber of the compressor to a suction port, an electrically-operated two-port control valve that selectively opens and closes a passage between the crankcase chamber and a discharge chamber, and pressure sensors for measuring the compressor discharge pressure and suction pressure. A plunger of the control valve is disposed within the passage coupling the crankcase chamber and the discharge chamber, and a solenoid armature linearly positions the plunger within the passage to open and close the passage. The plunger has an axial bore that forms a continuous passage between the discharge chamber and a cavity in which the discharge pressure sensor is retained so that the sensor is continuously exposed to the discharge pressure regardless of the plunger position.

摘要： A system is provided for etching patterned media disks. A movable electrode is utilized to perform sputter etch. The electrode moves to near or at slight contact to the substrate so as to couple RF energy to the disk. The material to be etched may be metal, e.g., Co/Pt/Cr or similar metals. The substrate is held vertically in a carrier and both sides are etched serially. That is, one side is etched in one chamber and then in the next chamber the second side is etched. An isolation valve is disposed between the two chambers and the disk carrier moves the disks between the chambers. The carrier may be a linear drive carrier, using, e.g., magnetized wheels and linear motors.

摘要： A sequence of process steps having balanced process times are implemented in sequence of etch chambers coupled linearly and isolated one from the other, resulting in the optimization of island to trench ratio for a patterned media. A biased chemical etching using active etching gas is used to descum and trim the resist patterns. An inert gas sputter etch is performed on the magnetic layers, resulting in the patterned magnetic layer on the disk. A final step of stripping is then performed to remove the residual capping resist and carbon hard mask on top of un-etched magnetic islands. The effective magnetic material remaining on the disk surface can be optimized by adjusting the conditions of chemical etch and sputter etch conditions. Relevant process conditions that may be adjusted include: pressure, bias, time, and the type of gas in each step.

摘要： A system is provided for etching patterned media disks for hard drive. The modular system may be tailored to perform specific processes sequences so that a patterned media disk is fabricated without removing the disk from vacuum environment. In some sequence the magnetic stack is etched while in other the etch is performed prior to forming the magnetic stack. In a further sequence ion implantation is used without etching steps. For etching a movable non-contact electrode is utilized to perform sputter etch. The cathode moves to near contact distance to, but not contacting, the substrate so as to couple RF energy to the disk. The substrate is held vertically in a carrier and both sides are etched serially. That is, one side is etched in one chamber and then in the next chamber the second side is etched.

摘要： A process chamber having high conductance and a method of manufacturing the process chamber are disclosed. The process chamber is machined from a single piece of aluminum where a process cavity and a pump cavity are created by intersecting cylinders. A substrate opening is also created at a bottom of the process cavity to provide conduit for services, such as cooling gas and electrical connections. A large undercut area is formed at a top of the pump cavity between the pump cavity and the process cavity. The undercut extends past the process chamber centerline at the process cavity. A circular saw is used to remove material and create a plenum which extends beyond the process cavity centerline.

摘要： A gas in a vacuum plasma processing chamber is ignited to a plasma by subjecting the gas to an r.f. field derived from an r.f. source having a frequency and power level sufficient to ignite the gas into the plasma and to maintain the plasma. The r.f. field is supplied to the gas by a reactive impedance element connected via a matching network to the r.f. source. The matching network includes first and second variable reactances that control loading of the source and tuning a load, including the reactive impedance element and the plasma, to the source. The value of only one of the reactances is varied until a local maximum of a function of power coupled between the source and the load is reached. The value of only the other reactance is varied until a local maximum of the function is reached. The two varying steps are then repeated as necessary.
