Patent number: 7115523Abstract: A process is provided for etching a silicon based material in a substrate, such as a photomask, to form features with straight sidewalls, flat bottoms, and high profile angles between the sidewalls and bottom, and minimizing the formation of polymer deposits on the substrate. In the etching process, the substrate is positioned in a processing chamber, a processing gas comprising a fluorocarbon, which advantageously is a hydrogen free fluorocarbon, is introduced into the processing chamber, wherein the substrate is maintained at a reduced temperature, and the processing gas is excited into a plasma state at a reduced power level to etch the silicon based material of the substrate. The processing gas may further comprise an inert gas, such as argon.Type: GrantFiled: March 18, 2003Date of Patent: October 3, 2006Assignee: Applied Materials, Inc.Inventors: Brigitte C.

Patent number: 6899111Abstract: The present invention provides a method and an apparatus for cleaning substrates. The cleaning chamber defines a processing cavity adapted to accommodate a substrate therein. In one embodiment, the cleaning chamber includes a chamber body having a processing cavity defined therein. A substrate is disposed in the processing cavity without contacting other chamber components by a Bernoulli effect and/or by a fluid cushion above and/or below the substrate. Fluid is flowed into the processing cavity at an angle relative to a radial line of the substrate to induce and/or control rotation of the substrate during a cleaning and drying process.Type: GrantFiled: October 31, 2001Date of Patent: May 31, 2005Assignee: Applied Materials, Inc.Inventors: Paul E.

Patent number: 6863835Abstract: A plasma chamber apparatus and method employing a magnet system to block the plasma within the chamber interior from reaching the exhaust pump. An exhaust channel between the chamber interior and the pump includes a magnet and at least one deflector that creates turbulence in the flow of exhaust gases. The magnetic field and the turbulence produced by the deflector both increase the rate of recombination of charged particles in the gases, thereby reducing the concentration of charged particles sufficiently to quench the plasma downstream of the magnet and deflector, thereby preventing the plasma body within the chamber from reaching the exhaust pump. The plasma confinement effect of the magnetic field permits the use of a wider and/or less sinuous exhaust channel than would be required to block the plasma without the magnetic field.Type: GrantFiled: April 25, 2000Date of Patent: March 8, 2005Inventors: James D. Carducci, Hamid Noorbakhsh, Evans Y. Lee, Hongqing Shan, Siamak Salimian, Paul E. Luscher, Michael D. Welch

Patent number: 6689249Abstract: A ring or collar surrounding a semiconductor workpiece in a plasma chamber. According to one aspect, the ring has an elevated collar portion having an inner surface oriented at an obtuse angle to the plane of the workpiece, this angle preferably being 135°. This angular orientation causes ions bombarding the inner surface of the elevated collar to scatter in a direction more parallel to the plane of the workpiece, thereby reducing erosion of any dielectric shield at the perimeter of the workpiece, and ameliorating spatial non-uniformity in the plasma process due to any excess ion density near such perimeter. In a second aspect, the workpiece is surrounded by a dielectric shield, and the shield is covered by a non-dielectric ring which protects the dielectric shield from reaction with, or erosion by, the process gases.Type: GrantFiled: September 4, 2001Date of Patent: February 10, 2004Assignee: Applied Materials, IncInventors: Kuang-Han Ke, Bryan Y.

Patent number: 6513452Abstract: A method of adjusting the cathode DC bias in a plasma chamber for fabricating semiconductor devices. A dielectric shield is positioned between the plasma and a selected portion of the electrically grounded components of the chamber, such as the electrically grounded chamber wall. The cathode DC bias is adjusted by controlling one or more of the following parameters: (1) the surface area of the chamber wall or other grounded components which is blocked by the dielectric shield; (2) the thickness of the dielectric; (3) the gap between the shield and the chamber wall; and (4) the dielectric constant of the dielectric material. In an apparatus aspect, the invention is a plasma chamber for fabricating semiconductor devices having an exhaust baffle with a number of sinuous passages. Each passage is sufficiently long and sinuous that no portion of the plasma within the chamber can extend beyond the outlet of the passage.Type: GrantFiled: April 24, 2001Date of Patent: February 4, 2003Assignee: Applied Materials Inc.Inventors: Hongching Shan, Evans Y.
