Publication number: 20040018450Abstract: A method for transferring patterns. After a patterned photoresist is formed on a substrate, the patterned photoresist is hardened, and the pattern of the hardened patterned photoresist is transferred into the substrate. Moreover, a popular method to harden is the silylation process, it is acceptable to only harder the top of the patterned photoresist or to harden both the top and the sidewall of the patterned photoresist. Besides, it is optional to change the thickness and the critical dimension of the patterned photoresist before it is hardened. Significantly, because the etch resistance of hardened patterned photoresist is higher than that of the non-hardened patterned photoresist, the method can improve any defect induced by etched photoresist during the pattern transferring process. Similarly, because a thinner non-hardened photoresist is available for the method, a smaller critical dimension of the patterned photoresist is available for the method while the photolithography technology being not improved.Type: ApplicationFiled: July 25, 2002Publication date: January 29, 2004Applicant: UNITED MICROLECTRONICS CORP.Inventors: Cheng-Yu Fang, Chih-Hsien Huang, Lawrence Lin, Jui-Tsen Huang
