  • Electron beam and x-ray resists
    Patent number: 4868241
    Abstract: Polymers are disclosed comprising a poly(vinyl alcohol) backbone with the following groups or combination of groups bound to the backbone:(A) (substituted alkyl)benzoyl groups; or(B) (substituted alkyl)benzoyl groups, and (vinyl)benzoyl groups; or(C) (substituted alkyl)benzoyl groups, and (halo)benzoyl groups or (2-carboxy-3,4,5,6-tetrachloro) benzoyl groups;(D) (substituted alkyl)benzoyl groups, (vinyl) benzoyl groups, and (halo)benzoyl groups or (2-carboxy-3,4,5,6-tetrachloro)benzoyl groups;(E) (vinyl)benzoyl groups, and (halo)benzoyl groups or (2-carboxy-3,4,5,6-tetrachloro) benzoyl groups; or(F) (halo)benzoyl groups.Each of these polymers can optionally contain, bound to the poly(vinyl alcohol) backbone, (trialkylsily) benzoyl groups.The benzoyl groups are randomly bound to the poly(vinyl alcohol) by ester linkages. Residual pendant hydroxy groups remain after the attachment of the benzoyl groups.
