ABSTRACT:
A photosensitive material which is very low in absorption of a light source of short wavelength and excellent in dry etch resistance. This photosensitive material comprises a compound having a terpenoid skeleton. Preferably, the compound having a terpenoid skeleton is a compound having a monovalent menthyl group or menthyl derivative group which can be represented by the general formula (1). ##STR1## wherein R is a hydrogen atom or a monovalent hydrocarbon group, R.sup.1 may be the same with or different from each other and individually represents a hydrogen atom, a halogen atom, a hydrocarbon group, a hydroxyl group, an alkoxyl group, an amino group, an alkoxy group, an amino group, an imide group, an amide group, or a sulfonyl group, a carboxyl group, a carbonyl group, or a sulfonamide group, and a pair of neighboring R.sup.1 may be connected together to form a closed ring.
