  • Patent number: 7160670
    Abstract: A scintillating structure for aligning an electron or ion beam using a detector while exposing a wafer, which may be a wafer or mask, is described. The structure is formed by a resist including a polymer with carboxylic acid groups, anhydride groups, and an acid-sensitive group, for instance tert.-butylester; a photoreactive compound which releases an acid upon irradiation with UV light, electrons, or ions; a solvent; and at least one scintillating substance such as anthracene, naphthaline and/or 1,4-bis-(5-phenyl-2-oxazolyl)-benzol. After a developing and silylating step, the cross-linked structure is inert with respect to solvents of additional resists that are applied over the structure. The scintillating structure is thus not dissolved, which improves the quality of online controlled electron or ion beam writing.

  • Patent number: 7157215
    Abstract: A photoresist with adjustable polarized light response and a photolithography process using the photoresist. The photoresist and the photolithography process are suitable for use in an exposure optical system with a high numerical aperture. The photoresist includes a photosensitive polymer that can absorb the exposure light source to generate an optical reaction. The photosensitive polymer can also be oriented along a direction of an electric field or a magnetic field. The response for the photosensitive upon a polarized light is determined by an angle between the predetermined direction and the polarized light. In addition, the photolithography process adjusts the orientation of the photosensitive polymer, so that the P-polarized light has a weaker response than that of the S-polarized light to compensate for the larger transmission coefficient of the P-polarized light with a high numerical aperture, so as to prevent the photoresist pattern deformation.

  • Patent number: 7108958
    Abstract: Anti-reflective compositions and methods of using these compositions to form circuits are provided. The compositions comprise a polymer dissolved or dispersed in a solvent system. Preferred polymers include polycarbonates, polysulfonyl esters, polycarbonate sulfones, and mixtures thereof. The compositions can be applied to a silicon wafer or other substrate to form a cured or hardened layer which is initially insoluble in typical photoresist developing solutions. Upon exposure to light, the cured or hardened layers become soluble in photoresist developing solutions so that the layer can be selectively removed along with the developed photoresist layer, thus eliminating the need for a separate removal step.
