    摘要: Disclosed is a process for forming an image on a substrate, comprising the steps of: (a) coating on the substrate a first layer of a radiation sensitive, antireflective composition; (b) coating a second layer of a photoresist composition onto the first layer of the antireflective composition; (c) selectively exposing the coated substrate from step (b) to actinic radiation; and (d) developing the exposed coated substrate from step (c) to form an image; wherein both the photoresist composition and the antireflective composition are exposed in step (c); both are developed in step (d) using a single developer; wherein the antireflective composition of step (a) is a first minimum bottom antireflective coating (B.A.R.C.) composition, having a solids content of up to about 8% solids, and a maximum coating thickness of the coated substrate of λ/2n wherein λ is the wavelength of the actinic radiation of step (c) and n is the refractive index of the B.A.R.C. composition.
