titleOfInvention |
Upper layer film forming composition and method of forming photoresist pattern |
abstract |
An upper layer film forming composition for forming an upper layer film on the surface of a photoresist film includes (A) a resin dissolvable in a developer for the photoresist film and (B) a compound having a sulfonic acid residue group, the composition forming an upper layer film with a receding contact angle to water of 70° or more. The upper layer film forming composition of the present invention can form an upper layer film which has a sufficient transparency and is stably maintained without eluting the components into a medium without being intermixed with a photoresist film, can form a resist pattern with high resolution while effectively suppressing a defect, and can suppress a blob defect. |
