Patent ID: 10976661

Abstract:
A resist composition which generates an acid when exposed and whose solubility in a developer is changed by an action of an acid, the resist composition including a polymer compound (A1) which has a constitutional unit (a0) derived from a compound represented by Formula (a0-1) and a constitutional unit (a10) derived from a compound represented by Formula (a10-1) and does not have a constitutional unit represented by Formula (1). In the formulas, Rax0 and Rax1 represent a polymerizable group-containing group; Wax0 and Wax1 represent an (nax0+1)-valent or (nax1+1)-valent aromatic hydrocarbon group; nax0 and nax1 represent an integer of 1 to 3; and Z2 represents Fe, Co, Ni, Cr, or Ru.
