    Abstract: The present invention discloses an inductively coupled coil and an inductively coupled plasma device using the same. The inductively coupled coil comprises an internal coil and an exterior coil which are respective from each other and coaxially arranged, internal coil comprising a plurality of internal respective branches having the same configurations which are nested together, the plurality of internal respective branches being arranged symmetrically with respect to an axis of the inductively coupled coil; the to external coil comprising a plurality of external respective branches having the same configurations which are nested together, the plurality of external respective branches being arranged symmetrically with respect to the axis of the inductively coupled coil. The inductively coupled coil is located on the reaction chamber of the inductively coupled plasma device and is connected to a RF source. It can make the plasma distribute uniformly on the wafer in the reaction chamber so that the difference in chemical reaction rate on the surface of the wafer is small and the quality of the etched wafer is improved. They can be applied in a semiconductor wafer manufacturing apparatus, and they can also be adapted to other apparatuses.

    Abstract: A plasma system includes an RF generator and a matchbox including an impedance matching circuit, which is coupled to the RF generator via an RF cable. The plasma system includes a chuck and a plasma reactor coupled to the matchbox via an RF line. The RF line forms a portion of an RF supply path, which extends between the RF generator through the matchbox, and to the chuck. The plasma system further includes a phase adjusting circuit coupled to the RF supply path between the impedance matching circuit and the chuck. The phase adjusting circuit has an end coupled to the RF supply path and another end that is grounded. The plasma system includes a controller coupled to the phase adjusting circuit. The controller is used for changing a parameter of the phase adjusting circuit to control an impedance of the RF supply path based on a tune recipe.

    Abstract: A plasma processing tool is used to deposit material on a workpiece. For example, a method for conformal deposition of material is disclosed. In this embodiment, the plasma sheath shape is modified to allow material to impact the workpiece at a range of incident angles. By varying this range of incident angles over time, a variety of different features can be deposited onto. In another embodiment, a plasma processing tool is used to etch a workpiece. In this embodiment, the plasma sheath shape is altered to allow ions to impact the workpiece at a range of incident angles. By varying this range of incident angles over time, a variety of differently shaped features can be created.

    Abstract: A tunable multi-zone injection system for a plasma processing system for plasma processing of substrates such as semiconductor wafers. The system includes a plasma processing chamber, a substrate support for supporting a substrate within the processing chamber, a dielectric member having an interior surface facing the substrate support, the dielectric member forming a wall of the processing chamber, a gas injector fixed to part of or removably mounted in an opening in the dielectric window, the gas injector including a plurality of gas outlets supplying process gas at adjustable flow rates to multiple zones of the chamber, and an RF energy source such as a planar or non-planar spiral coil which inductively couples RF energy through the dielectric member and into the chamber to energize the process gas into a plasma state. The injector can include an on-axis outlet supplying process gas at a first flow rate to a central zone and off-axis outlets supplying the same process gas at a second flow rate to an annular zone surrounding the central zone. The arrangement permits modification of gas delivery to meet the needs of a particular processing regime by allowing independent adjustment of the gas flow to multiple zones in the chamber. In addition, compared to consumable showerhead arrangements, a removably mounted gas injector can be replaced more easily and economically.
