SUBSTRATE CARRIER
Embodiments of substrate carriers and method of making the same are provided herein. In some embodiments, a substrate carrier includes a substantially planar body; and a plurality of holding elements arranged on a surface of the substantially planar body, wherein the plurality of holding elements are configured to hold a plurality of substrates on the surface of the substantially planar body, and wherein the plurality of holding elements includes at least three holding elements disposed around a corresponding position of each of the plurality of substrates.
CARRIER RINGS WITH RADIALLY-VARIED PLASMA IMPEDANCE
Carrier rings with radially-varied plasma impedance are provided herein. In some embodiments, a carrier ring may include an outer ring that holds a removable inner ring. The outer ring may be formed of a dielectric material such as ceramic. The inner ring may be formed of a metal such as aluminum to provide a desired impedance. In some other embodiments, a carrier ring is formed from a single piece with radially-varying impedances.
REACTION CHAMBER
A reaction chamber includes a chamber body and a base. The base is arranged in the chamber body. The base includes a carrier member, a first block ring, and a second block ring. The carrier member is configured to carry a substrate and an edge member arranged around the carrier member. A height of an upper surface of the carrier member is greater than a height of an upper surface of the edge member. The first block ring is arranged on the upper surface of the edge member and around the carrier member. The upper surface of the carrier member is higher than an upper surface of the first block ring. The second block ring is on the upper surface of the first block ring. The second block ring includes a body member and a shield member.
METHOD OF MANUFACTURING A SUBSTRATE SUPPORT FOR A LITHOGRAPHIC APPARATUS, SUBSTRATE TABLE, LITHOGRAPHIC APPARATUS, DEVICE MANUFACTURING METHOD, METHOD OF USE
Substrate tables and methods of manufacturing substrate supports for substrate tables. In one arrangement, a plurality of holes are formed through a base member. A burl formation member is joined to the base member. A plurality of burl structures are formed in the burl formation member. Each burl structure includes a distal surface that contacts, in use, a substrate being supported. Each burl structure has an opening to at least one of the holes formed through the base member.
METHODS AND APPARATUS FOR ADJUSTING SURFACE TOPOGRAPHY OF A SUBSTRATE SUPPORT APPARATUS
Systems, method and related apparatuses for adjusting support elements of a support apparatus to approximate a surface profile of a wafer. The support apparatus may include a group of mutually lateral adjacent support elements, each mutually lateral adjacent support element is configured to independently move at least vertically and comprising an upper surface. The support apparatus may further include a thermal energy transfer device operably coupled to each of the mutually lateral support elements, and an actuator system operably coupled to each of the support elements to selectively move one or more of the mutually lateral support elements vertically.
FACE-UP WAFER EDGE POLISHING APPARATUS
Exemplary substrate edge polishing apparatuses may include a chuck body defining a substrate support surface. The apparatuses may include an edge ring seated on the chuck body. The apparatuses may include a retaining wall disposed radially outward of the edge ring. The apparatuses may include a slurry delivery port disposed radially inward of the retaining wall. The apparatuses may include a cylindrical spindle that is positionable over the chuck body. The apparatuses may include an annular polishing pad coupled with a lower end of the cylindrical spindle.
Heater cover plate for uniformity improvement
Embodiments of the present disclosure generally relate to an apparatus for improving the film thickness on a substrate when using a heated substrate support. A cover plate to be placed over the top surface of a heated substrate support is disclosed. The cover plate includes a pocket formed in the middle thereof for the placement of a substrate. The cover plate may include a variety of features including a plurality of dimples, a plurality of radially disposed grooves, a plurality of annular grooves, lift pin holes, pin slots, and gas exhaust holes.
PLASMA PROCESSING APPARATUS, AND METHOD AND PROGRAM FOR CONTROLLING ELEVATION OF FOCUS RING
A plasma processing apparatus includes a mounting table, an acquisition unit, a calculation unit, and an elevation control unit. The mounting table mounts thereon a target object as a plasma processing target. The elevation mechanism vertically moves a focus ring surrounding the target object. The acquisition unit acquires state information indicating a measured state of the target object. The calculation unit calculates a height of the focus ring at which positional relation between an upper surface of the target object and an upper surface of the focus ring satisfies a predetermined distance based on the state of the target object that is indicated by the state information acquired by the acquisition unit. The elevation control unit controls the elevation mechanism to vertically move the focus ring to the height calculated by the calculation unit.
METHOD AND APPARATUS FOR PLASMA DICING A SEMI-CONDUCTOR WAFER
The present invention provides a method for plasma dicing a substrate. The method comprising providing a process chamber having a wall; providing a plasma source adjacent to the wall of the process chamber; providing a work piece support within the process chamber; placing the substrate onto a support film on a frame to form a work piece work piece; loading the work piece onto the work piece support; providing a clamping electrode for electrostatically clamping the work piece to the work piece support; providing a mechanical partition between the plasma source and the work piece; generating a plasma through the plasma source; and etching the work piece through the generated plasma.
FLAT BOTTOM SHADOW RING
In some examples, a flat Bottom Shadow Ring (fBSR) is provided for processing a substrate in a processing chamber. An example fBSR comprises an overhang for covering an edge of the substrate in the processing chamber. The overhang includes a fiat zone that extends radially outward over the outer edge of the substrate.
