Publication number: 20070193602Abstract: Plasma systems and methods for supplying activation energy to remove cross-linked photoresist crust using ion bombardment of the substrate from a plasma, at reduced temperature, achieved in part by operating the processing chamber at low pressures. Reduced temperatures prevent “popping” of the photoresist which can cause particulate contamination. The gas flow may comprise a principal gas, an inert diluent gas, and an additive gas. Principal gases for HDIS may comprise oxygen, hydrogen, and water vapor at pressures less than about 200 mTorr and a bias may be applied to the substrate support. When low-k dielectric material is present on vertical surfaces, reduced ion bombardment on vertical surfaces may be used, and a protective layer may be deposited on those surfaces.Type: ApplicationFiled: March 27, 2007Publication date: August 23, 2007Inventors: Stephen Savas, John Zajac, Robert Guerra, Wolfgang Helle

Patent number: 7232767Abstract: A more uniform plasma process is implemented for treating a treatment object using an inductively coupled plasma source which produces an asymmetric plasma density pattern at the treatment surface using a slotted electrostatic shield having uniformly spaced-apart slots. The slotted electrostatic shield is modified in a way which compensates for the asymmetric plasma density pattern to provide a modified plasma density pattern at the treatment surface. A more uniform radial plasma process is described in which an electrostatic shield arrangement is configured to replace a given electrostatic shield in a way which provides for producing a modified radial variation characteristic across the treatment surface. The inductively coupled plasma source defines an axis of symmetry and the electrostatic shield arrangement is configured to include a shape that extends through a range of radii relative to the axis of symmetry.Type: GrantFiled: March 18, 2004Date of Patent: June 19, 2007Assignee: Mattson Technology, Inc.Inventors: Rene George, Andreas Kadavanich, Daniel J. Devine, Stephen E. Savas, John Zajac, Hongching Shan
