Patent number: 10101669Abstract: A technique which, in forming a resist pattern on a wafer, can achieve high resolution and high in-plane uniformity of pattern line width. After forming a resist film on a wafer W and subsequently performing pattern exposure by means of a pattern exposure apparatus, the entire pattern exposure area is exposed by using a flood exposure apparatus. During the flood exposure, the exposure amount is adjusted depending on the exposure position on the wafer based on information on the in-plane distribution of the line width of a resist pattern, previously obtained from an inspection apparatus. Methods for adjusting the exposure amount include a method which adjusts the exposure amount while moving a strip-shaped irradiation area corresponding to the diameter of the wafer, a method which involves intermittently moving an irradiation area, corresponding to a shot area in the preceding pattern exposure, to adjust the exposure amount for each chip.Type: GrantFiled: January 13, 2015Date of Patent: October 16, 2018Assignee: Tokyo Electron LimitedInventors: Seiji Nagahara, Gousuke Shiraishi, Satoru Shimura, Kousuke Yoshihara, Shinichiro Kawakami, Masaru Tomono, Yuichi Terashita, Hironori Mizoguchi

Patent number: 9097977Abstract: A method for patterning a substrate with reduced defectivity is described. Once a pattern is formed in a layer of radiation-sensitive material using lithographic techniques, the pattern formed on the substrate is post-treated. The post-treating of the pattern in the layer of radiation-sensitive material is performed to reduce a roughness of the pattern. The post-treating includes performing a treatment process on the pattern to alter a solubility of an exposed surface of the pattern, wherein the treatment process involves performing a first chemical treatment of the pattern using a liquid-phase chemical solution containing a first surfactant, or exposing said pattern to second EM radiation different than said first EM radiation. Following the treatment process, the post-treating includes hard baking the pattern, and performing a second chemical treatment of the pattern using a vapor-phase chemical solution to reduce the roughness.Type: GrantFiled: August 10, 2012Date of Patent: August 4, 2015Assignee: Tokyo Electron LimitedInventor: Shinichiro Kawakami
