A novel anthracene derivative useful as an additive to a radiation-sensitive resin composition is disclosed. The anthracene derivative has the following formula (1),
1
wherein R
1
groups individually represent a hydroxyl group or a monovalent organic group having 1-20 carbon atoms, n is an integer of 0-9, X is a single bond or a divalent organic group having 1-12 carbon atoms, and R
2
represents a monovalent acid-dissociable group. The radiation-sensitive resin composition comprises the anthracene derivative of the formula (1), a resin insoluble or scarcely soluble in alkali, but becomes alkali soluble in the presence of an acid, and a photoacid generator. The composition is useful as a chemically-amplified resist for microfabrication utilizing deep ultraviolet rays, typified by a KrF excimer laser and ArF excimer laser.
A novel photoacid generator containing a structure of the following formula (I),
1
wherein R is a monovalent organic group with a fluorine content of 50 wt % or less, a nitro group, a cyano group, or a hydrogen atom, and Z
1
and Z
2
are individually a fluorine atom or a linear or branched perfluoroalkyl group having 1-10 carbon atoms, is provided. When used in a chemically amplified radiation-sensitive resin composition, the photoacid generator exhibits high transparency, comparatively high combustibility, and no bioaccumulation, and produces an acid exhibiting high acidity, high boiling point, moderately short diffusion length in the resist coating, and low dependency to mask pattern density.
