Abstract
One embodiment of the present invention provides a pattern forming method including a step for forming an actinic ray-sensitive or radiation-sensitive film on a substrate using an actinic ray-sensitive or radiation-sensitive resin composition, a step for forming an upper layer film on the actinic ray-sensitive or radiation-sensitive film using a composition for forming an upper layer film, a step for exposing a laminate film including the actinic ray-sensitive or radiation-sensitive film and the upper layer film, and a step for developing the exposed laminate film using a developer including an organic solvent. The composition for forming an upper layer film contains a resin (XA), a resin (XB) containing fluorine atoms, a basic compound (XC), and a solvent (XD), and the resin (XA) is a resin not containing fluorine atoms, or in a case where the resin (XA) contains fluorine atoms, the resin (XA) is a resin having a lower content of fluorine atoms than that in the resin (XB), based on a mass.
