    Abstract: In plasma activated chemical vapour deposition a plasma decomposition unit is used that is arranged in or connected to a vacuum vessel having a relatively low pressure or vacuum, to which an operating gas is provided. Periodically repeated voltage pulses are applied between the anode and the cathode of the plasma decomposition unit in such a manner that pulsed electric discharges are produced between the cathode and the surrounding anode of the plasma decomposition unit. The anode is arranged in a special way so that at least a portion thereof will obtain only an electrically conductive coating or substantially no coating when operating the unit. For that purpose, the anode includes a portion located in the direct vicinity of the free surface of the cathode. The portion is a flange or edge portion which is located or extends over margins of the free surface of the cathode.

  • Publication number: 20110005920
    Abstract: Various embodiments of the present invention are generally directed to an apparatus and method for low temperature physical vapor deposition (PVD) of an amorphous thin film layer of material onto a substrate. A PVD chamber is configured to support a substrate and has a cathode target with a layer of sputtering material thereon, an anode shield, and a magnetron assembly adjacent the target. A high impulse power magnetron sputtering (HiPIMS) power supply is coupled to the PVD chamber, the power supply having a charging circuit and a charge storage device. The power supply applies relatively high energy, low duty cycle pulses to the magnetron assembly to sputter, via self ionizing plasma, relatively low energy ions from the layer of sputtering material to deposit an amorphous thin film layer onto the substrate.

    Abstract: This application discloses a thin-film deposition apparatus comprising a vacuum chamber and a partition separating the inside of the vacuum chamber into two areas. A substrate is capable of passing through an inside opening provided in the partition. The inside opening is closed by a valve. A thin film is deposited onto the substrate in the first area. The substrate is heated by a heater in the second area prior to the deposition. The substrate is held by a holder in point contact while heated. A boosting-gas is introduced into the second area during the heating, thereby increasing pressure up to a viscous flow range. A pumping line evacuates the first area at a vacuum pressure all the time. The pumping line also evacuates the introduced boosting-gas from the second area to make the second area at a vacuum pressure when the valve is opened.

  • Publication number: 20090211897
    Abstract: The present invention provides a multi-target sputtering apparatus including an increased number of targets which can be sputtered simultaneously, and a method for controlling the sputtering apparatus. In one embodiment of the present invention, first and second shutter plates are provided between a substrate and target electrodes and paths between intended targets and the substrate are shut off by the shutter plates to perform a pre-sputtering step. In addition, the first and second shutter plates are rotated as appropriate at the time of transition to a full-scale sputtering step, so as to overlap through-holes provided in the shutter plates, thereby opening up paths between the intended targets and the substrate. Then, a full-scale sputtering step is performed.

  • Publication number: 20090200159
    Abstract: In a reactive sputtering apparatus, an inert-gas supplying hole is provided in a movable target unit whose one end is open and whose conductance is controlled, and a reactive gas containing at least fluorine or oxygen can be supplied to a space between the target and a substrate. The apparatus is constructed so as to emit the reactive gas toward the substrate. A reactive-gas emitting location is in the space between the target and the substrate such that a concentration of the reactive gas on the substrate surface can be maintained at a higher level. When the target is moved, a reactive-gas emitting port is moved or the reactive-gas emitting location is changed. The concentration of the reactive gas on the substrate surface can be effectively kept constant, and a high-quality optical thin film can be formed.

  • Patent number: 7569123
    Abstract: In one embodiment, the erosion profile of a shaped target (e.g., hollow cathode target) of a magnetron apparatus is enhanced by using a plurality of sputtering tracks, such as plasma loops, on the target. The erosion profile may be optimized by recording the erosion profile and making adjustments to the magnetic configuration of the magnetron. The recording may include two-dimensional plots of erosion/redepostion rates or a grid overlay tracing of a static burn test, for example. The magnetic configuration of the magnetron may include a rotating magnetic array. The rotating magnetic array may be adjusted to change the shape or location of the plurality of plasma loops to achieve an optimum erosion profile. The target may have a flared lip to increase erosion on the lip, if needed.

  • Patent number: 7556718
    Abstract: This invention relates to ionized PVD processing of semiconductor wafers and provides conditions for highly uniform deposition-etch process sequence and coverage capabilities of high aspect ratio (HAR) features within a single processing chamber. A plasma is generated and maintained by an inductively coupled plasma (ICP) source. A deposition process step is performed in which metal vapor is produced from a target of a PVD source. Location and sputter efficiency at the target surface is enhanced by moving a magnet pack to create a traveling or sweeping magnetic field envelope. The target is energized from a DC power supply and pressures effective for an efficient thermalization of the sputtered atoms (30<p<100 mTorr) are maintained in the chamber during deposition. A uniform thickness of the metal on the wafer is produced within each magnet sweeping cycle.

    Abstract: A method and system for depositing a thin film on a substrate. In the system a target material is deposited and reacted on a substrate surface to form a substantially non-absorbing thin film. The volume of non-absorbing thin film formed per unit of time may be increased by increasing the area of the surface by a factor of “x” and increasing the rate of deposition of the target material by a factor greater than the inverse of the factor “x” to thereby increase the rate of formation of the volume of non-absorbing thin film per unit of time.

  • Publication number: 20090139854
    Abstract: A control system and method for controlling two motors determining the azimuthal and circumferential position of a magnetron rotating about the central axis of the sputter chamber in back of its target sputtering and capable of a nearly arbitrary scan path, e.g., with a planetary gear mechanism. A system controller periodically sends commands to the motion controller which closely controls the motors. Each command includes a command ticket, which may be one of several values. The motion controller accepts only commands having a command ticket of a different value from the immediately preceding command. One command selects a scan profile stored in the motion controller, which calculates motor signals from the selected profile. Another command instructs a dynamic homing command which interrogates sensors of the position of two rotating arms to determine if the arms in the expected positions. If not, the arms are rehomed.
