  • Publication number: 20140206111
    Abstract: To improve the performance of a semiconductor device, a semiconductor device manufacturing method includes an exposing process of performing pattern exposure of a resist film formed on a substrate by using EUV light reflected from a front surface of an EUV mask as a reflective mask. In this exposing process, the resist film is subjected to pattern exposure by repeating a process of irradiating the resist film with the EUV light by changing a focal position of the EUV light with which the resist film is irradiated, along a film thickness direction of the resist film. After this exposing process, the resist film subjected to pattern exposure is developed to form a resist pattern.

  • Patent number: 8673543
    Abstract: A reverse pattern is formed once by combining a negative exposure mask having a wiring pattern with a positive resist, and then a positive wiring pattern is formed by use of the reverse pattern. That is, a positive resist applied on a semiconductor substrate is exposed by use of the exposure mask having an opening part in a region corresponding to the wiring pattern, and then the exposed part is removed by development to form a resist pattern, thereby forming the wiring pattern in the region corresponding to the opening part of the resist pattern. Consequently, it is hardly affected by flare during EUV exposure, thereby fabricating a fine wiring pattern with higher exposure latitude.
