Abstract:
A molecular glass compound comprises a vinyl ether adduct of an aromatic vinyl ether of formula C(R)═C(R)—O-(L)-Ar, and a calix[4]arene, wherein Rand Rare each independently a single bond, H, Calkyl, Chaloalkyl, Caryl, Chaloaryl, Caralkyl, or Chaloaralkyl, L is a Clinking group, n is 0 or 1, and Aris a halo-containing monocyclic, or substituted or unsubstituted polycyclic or fused polycyclic Caromatic-containing moiety, wherein Rand Rare connected to Arwhen either or both of Rand Ris a single bond and n is 0. A photoresist, comprising the molecular glass compound, a solvent, and a photoacid generator, a coated substrate, comprising (a) a substrate having one or more layers to be patterned on a surface thereof; and (b) a layer of a photoresist composition over the one or more layers to be patterned, and a method of forming the molecular glass compound, are also disclosed.
