The mask pattern includes a resist pattern formed on a semiconductor substrate and the self-assembled molecular layer formed on the resist pattern. The self-assembled molecular layer has a silica network formed by a sol-gel reaction. To form the mask pattern, first, the resist pattern is formed with openings on an underlayer covering the substrate to expose the underlayer to a first width. Then, the self-assembled molecular layer is selectively formed only on a surface of the resist pattern to expose the underlayer to a second width smaller than the first width. The underlayer is etched by using the resist pattern and the self-assembled molecular layer as an etching mask to obtain a fine pattern.

  • Patent number: 7704673
    Abstract: A photo acid generator (PAG) or an acid is used to reduce resist scumming and footing. Diffusion of acid from photoresist into neighbors causes a decreased acid level, and thus causes resist scumming. An increased acid layer beneath the resist prevents acid diffusion. In one embodiment, the increased acid layer is a layer of spun-on acid or PAG dissolved in aqueous solution. In another embodiment, the increased acid layer is a hard mask material with a PAG or an acid mixed into the material. The high acid content inhibits the diffusion of acid from the photoresist into neighboring layers, and thus substantially reduces photoresist scumming and footing.

By prior deterministic control over regional surface properties of the random copolymer film, domains of the diblock copolymer film form only in predefined areas. This approach offers simplified processing and a precise control of regions where domain formation occurs. Selective removal of some of the domains allows for further processing of the electronic component.
