Zusammenfassung: | A chemically amplified positive resist composition is provided comprising (A) a sulfurane or selenurane compound having formula (A1) wherein M is sulfur or selenium and (B) a base polymer containing a polymer comprising repeat units having formula (B1). The resist composition exhibits a high resolution during pattern formation and forms a pattern with improved LER and CDU. |
