    摘要: A method of manufacturing an electronic device, such as a high-speed semiconductor integrated circuit device, with improved dimensional accuracy in transferring fine patterns. Photolithography for gate patterns and wiring patterns is carried out by exposing a halftone phase-shift mask having shade areas made of resist with an oblique illumination system, and photolithography for contact hole patterns is carried out by using a photomask having a metal shade film with metal alignment wafer marks.

    摘要: A pattern is transferred to a resist film on a wafer by a reduction projection exposure method using a half-tone phase-shift mask in which is formed a half-tone phase-shifter pattern including a thin-film pattern functioning as an attenuator and a resist pattern functioning as the photosensitive composition for phase adjustment. This method improves the accuracy of dimensions of the pattern transferred to the wafer.

    摘要: A method of fabrication of a semiconductor integrated circuit device uses a mark having, on a first main surface of a mask substrate, a first light transmitting region, a second light transmitting region disposed at the periphery of the first light transmitting region and permitting inversion of the phase of light transmitted through the second light transmitting region relative to light transmitted through the first light transmitting region, and a light shielding region disposed at the periphery of the second light transmitting region. The second light transmitting region is formed from a first film deposited over the first main surface of the mask substrate, said light shielding region is formed by a second film deposited over the first main surface of the mask substrate via said first film, and at least one of said first film and second is formed from a resist film.
