    摘要: An actinic-ray-sensitive or radiation-sensitive resin composition capable of forming a pattern having excellent critical dimension uniformity (CDU) in the line width, and a pattern forming method using the same are provided.The actinic-ray-sensitive or radiation-sensitive resin composition of the present invention includes (A) a resin containing a repeating unit having a specific lactone structure and a repeating unit having a specific monocyclic alicyclic structure, which increases a solubility in an alkaline developer by the action of an acid, and (B) a compound having a specific structure, which generates an acid upon irradiation with an actinic-ray or a radiation.
