  • Patent number: 7971160
    Abstract: A method for creating a pattern on a photomask includes steps of recognizing a space between main patterns by using pattern data which indicate the main patterns to be adjacently transferred onto a wafer, determining a 1st rule about arrangement of an assist pattern on the photomask, the assist pattern being adjacent to the main patterns and not being transferred onto the wafer, estimating a depth of focus in the presence of the assist pattern among the main patterns, determining a 2nd rule about arrangement of the assist pattern on the photomask to improve the depth of focus in the presence of the 1st assist pattern among the main patterns in a group having one or more number of appearance times of the space between main patterns, and correcting the assist pattern on the photomask using the assist pattern data on the basis of the 2nd rule.

  • Patent number: 7790335
    Abstract: A double exposure process is performed using a halftone phase shift mask (11) including gate patterns (1), assist patterns (2a) and (2b) with different resoluble line widths, and an assist pattern (2c) with a line width equal to or smaller than a resolution limit which are respectively inserted into portions in each of which a distance between the gate patterns (1) is large, and a Levenson phase shift mask (11) including shifter patterns (3) corresponding to the gate patterns (1) of the photomask 11. On this occasion, the assist patterns (2a), (2b), and (2c) are erased and only the gate patterns (1) are transferred. Consequently, when patterns are transferred by the double exposure process, a common depth of focus of the patterns is improved and highly uniform line widths are realized, which makes it possible to manufacture a highly reliable semiconductor device.

  • Publication number: 20070231714
    Abstract: A photomask making method and a semiconductor-device manufacturing method to improve the uniformity of the line widths of patterns. A gate electrode pattern and a gate wiring pattern are formed in a first photomask used in a double exposure process, and shift patterns are formed in a second photomask. Then, assist patterns are disposed at sides of the gate electrode pattern, and assist patterns are disposed at sides of the gate wiring pattern, in the first photomask. Inclusion patterns that include the assist patterns are disposed in the second photomask. With the double exposure process using the first photomask and the second photomask, the depth of focus obtained when the gate electrode pattern and the gate wiring pattern are exposed is improved, the uniformity of the line widths of the gate electrode pattern and the gate wiring pattern is increased.

  • Patent number: 6969580
    Abstract: A resist pattern of a resist film is formed by exposing the resist film using a gate electrode forming mask (a Levenson phase shift mask), and developing the resist film. An antireflection film is etched using the resist pattern as an etching mask, and the resist pattern and the antireflection film are trimmed. The manner of this trimming is not to etch a hard mask made of an inorganic material, but to etch the resist pattern and the antireflection film made of an organic material. Since a region consistent with a wiring pattern of the hard mask is covered by the resist pattern completely, breaking down and retraction of the wiring are prevented.
