- a photosensitive composition using a compound having a tricyclodole structure that is a bridged alicyclic compound is known (Cited document 4), but when these are used as a resist to form a resist pattern by alkali development Since alicyclic structures such as the adamantane skeleton have a very high hydrophobicity, alkali solubility differs greatly from soluble groups such as carboxylic acid groups, and various problems occur. is doing.
- the dissolution and removal of a predetermined region of the resist film at the time of development becomes non-uniform, resulting in a decrease in resolution, and a decrease in resolution resulting from swelling after development of the resist pattern, and the resist film should remain. Even in the region, partial dissolution occurs and cracks and surface roughness occur.
- the coatability of the polymer is insufficient because the phase separation between the part having an alicyclic structure and a soluble group, for example, a carboxylic acid group in the polymer proceeds, and a uniform resist solution is not readily prepared.
