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.
摘要:
The present invention relates to novel negative-working, photoimageable, and aqueous developable antireflective coating compositions and their use in image processing by forming a thin layer of the novel antireflective coating composition between a reflective substrate and a photoresist coating. The negative bottom photoimageable antireflective coating composition is capable of being developed in an alkaline developer and is coated below a negative photoresist.
摘要:
The present invention relates to an undercoating composition for a photoresist comprising a polymer which is insoluble in an aqueous alkali developer but becomes soluble prior to development, and a photoacid generator which produces a strong acid upon exposure to radiation, and further where the polymer is transparent at the exposure radiation. The invention also relates to a process for imaging the undercoating composition.
