    摘要: An RF plasma etch reactor having an etch chamber with electrically conductive walls and a protective layer forming the portion of the walls facing the interior of the chamber. The protective layer prevents sputtering of material from the chamber walls by a plasma formed within the chamber. The etch reactor also has an inductive coil antenna disposed within the etch chamber which is used to generate the plasma by inductive coupling. Like the chamber walls, the inductive coil antenna is constructed to prevent sputtering of the material making up the antenna by the plasma. The coil antenna can take on any configuration (e.g. location, shape, orientation) that is necessary to achieve a desired power deposition pattern within the chamber. Examples of potential coil antenna configurations for achieving the desired power deposition pattern include constructing the coil antenna with a unitary or a segmented structure. The segmented structure involves the use of at least two coil segments wherein each segment is electrically isolated from the other segments and connected to a separate RF power signal. The unitary coil antenna or each of the coil segments can have a planar shape, a cylindrical shape, a truncated conical shape, a dome shape, or any combination thereof. The conductive walls are electrically grounded to serve as an electrical ground (i.e. anode) for a workpiece-supporting pedestal which is connected to a source of RF power to create a bias voltage at the surface of the workpiece.

    摘要: A method for controlling the operation of a magnetron source for sputtering a surface of a target in a vacuum chamber, the method including the steps of: during a low pressure phase of sputtering, causing a magnetic field generated by a the magnetron source to be confined primarily to an inner region of the surface of the target so as to reduce leakage of electrons away from the target during sputtering; and during a subsequent high pressure phase of sputtering, causing the magnetic field generated by the magnet assembly to extend into the outer region of the surface of the target so as to sputter material from the outer region of the surface of the target. The pressure of the high pressure phase of sputtering is higher than the pressure of the low pressure phase of sputtering.

    摘要: A readily removable deposition shield for processing chambers such as chemical vapor deposition (CVD), ion implantation, or physical vapor deposition (PVD) or sputtering chambers, is disclosed. The deposition shield includes a shield of cylindrical configuration (or other configuration conformed to the internal shape of the substrate and the chamber) which is mounted to the chamber for easy removal, such as by screws, and defines a space along the periphery of the substrate support. A shield ring is inserted into the peripheral space and is thus mounted in removable fashion and is automatically centered about the substrate. The shield ring overlaps the cylindrical shield and the substrate support. Collectively, these components prevent deposition on the chamber and hardware outside the processing region. Also, the cylindrical shield and the shield ring may be removed as a unit. Locating means such as pins may be mounted or formed in the support about the periphery of the substrate for centering the substrate. Also, a peripheral groove may be formed in the substrate support peripheral to the substrate, for preventing material deposited on the support peripheral to the substrate from sticking to the substrate. The substrate is supported on spacers mounted on the substrate support; the resulting gap between the substrate and the support also prevents the material deposited on the support from bonding to the substrate. The result of the various features is an effective shield which allows long intervals before the shield must be removed for cleaning or replacement and which is easy to remove when necessary. In addition, the entire upper surface of the substrate is available for processing.

    摘要: A vacuum processing system has a transfer chamber with a slit valve at which is attached a process chamber and with a slit valve insert disposed in the slit valve for matching up with the process chamber. The slit valve may be made of two pieces, an outer portion that slides into the transfer chamber's slit valve opening from the outside of the transfer chamber, and an inner portion that slides into the outer portion from the inside of the transfer chamber. The portions of the insert permit any process chamber to be attached to any slit valve opening. The outer portion may not be removed from the slit valve opening when a process chamber is attached to the transfer chamber, but the inner portion may be easily removed for servicing regardless of in whether a process chamber is attached.
