    摘要: A problem of a decrease in transmissive light, which partly occurs at a boundary between two polarization modulation regions of a polarized phase shift mask, is solved. A photomask for use in an exposure apparatus which forms an exposure pattern by illumination includes at least two polarization modulation regions which produce mutually incoherent polarized light components and adjoin each other, at least two phase modulation regions which impart a phase difference of 180° and adjoin each other, and amplitude modulation regions which decrease transmittance. A contact line between the polarization modulation regions and a contact line between the phase modulation regions are located at a corresponding position, and the amplitude modulation regions are provided on both sides of the common contact line, with a predetermined distance from the common contact line.

    摘要: A crystallization apparatus includes an image forming optical system which has an image side numerical aperture set to a value required to generate a light intensity distribution with an inverse peak pattern and sets an amorphous semiconductor film and a phase shift mask to an optically conjugate relationship. The phase shift mask has a boundary area which extends along a first axial line, and a first area and a second area which are arranged on both sides of the boundary area have a predetermined phase difference therebetween. The boundary area has a phase distribution which varies from a phase of the first area to a phase of the second area.

    摘要: A light irradiation apparatus includes a light modulation element which has a phase modulation area having at least one basic pattern for modulating a light beam, an illumination system which illuminates the phase modulation area of the light modulation element with a light beam, and an image formation optical system which causes a light beam on an irradiation target surface a light intensity distribution having an inverse-peak-shaped pattern formed based on the light beam phase-modulated by the phase modulation element to fall on an irradiation target object. Dimensions of the basic pattern are not greater than a point spread function range of the image formation optical system converted in terms of the light modulation element. The phase modulation area is configured in such a manner that a phase distribution in a light complex amplitude distribution on the irradiation target surface becomes a saw-tooth-like distribution along a line segment in a lateral direction.
