Patent number: 6744494Abstract: An apparatus for compensating light exposure on different, subsequently irradiated target areas (11, 12) in a photosensitive medium (2) on a semiconductor wafer (1). In order to improve exposure dose uniformity the apparatus comprises a mask filter (9) with a plurality of oblong transparent (31) and oblong opaque elements (32; 41) inserted between a light source (3) and said photosensitive medium (2) so that light (4) traverses through said plurality of transparent elements (31) to expose the photosensitive medium. Each of said plurality of oblong opaque elements (32; 41) is rotatable around a longitudinal axis (42) so as to define the area masked by the projection of the opaque element on the photosensitive medium and to continuously adjust a ratio between irradiated and non-irradiated areas on the photosensitive medium.Type: GrantFiled: December 7, 2001Date of Patent: June 1, 2004Assignee: Motorola, Inc.Inventors: John Maltabes, Karl Mautz, Alain Charles

Patent number: 6650135Abstract: A metrology and probe chuck (100) holds a flat object (150), such as a semiconductor wafer (150) at the backside (152). The chuck has, supported on a base plate (105), a plurality of pins (110-n) to receive partial forces (Fn) from the backside (152) and a plurality of piezoelectric elements (120-n) attached to the pins to sense the partial forces (Fn) applied from the object (150) to the pins (110-n). The piezoelectric elements (120-n) apply partial displacements (Bn) of the pins (110-n) to act on selected areas of the object (150) and thereby compensate for irregularities in the backside contour.Type: GrantFiled: June 29, 2000Date of Patent: November 18, 2003Assignee: Motorola, Inc.Inventors: Karl Mautz, John Maltabes, Alain Charles

Patent number: 6589099Abstract: Chemical mechanical polishing (CMP) a metal film (155) at the surface of a substrate (150), with mixing a slurry precursor (201) with an oxidizing agent (202) to provide a slurry (200) with a predetermined agent concentration, and supplying the slurry to a CMP pad (140) to polish the film at a predetermined polishing rate is modified by altering the agent concentration at the end of polishing. Since the polishing rate is reduced, endpointing is enhanced. The concentration is altered by adding further oxidizing or reducing agents.Type: GrantFiled: July 9, 2001Date of Patent: July 8, 2003Assignee: Motorola, Inc.Inventors: David Weston Haggart, Jr., John Maltabes, Karl Emerson Mautz

Publication number: 20020051567Abstract: A lithographic tool can be adjusted by inspecting wafer images of an defect inspection tool and correlating the wafer images with images from a reference library in a database. Each reference image in the database corresponds to an initially measured amount of miss adjustment of lithographic tool parameters. The lithographic tool is adjusted automatically according to the reference image that is found to have the greatest resemblance to the wafer image. Time for adjusting is saved, operator staff needed is reduced, and objective determination criteria provide high wafer quality and yield.Type: ApplicationFiled: September 4, 2001Publication date: May 2, 2002Inventors: Dietmar Ganz, John Maltabes, Thorsten Schedel
