Abstract: A contact hole forming method uses a negative resist film having an absorptivity of 0.5 .mu.m.sup.-1 or above to suppress standing-wave effect in forming contact holes in a silicon dioxide film or the like underlying the negative resist film by anisotropic etching. The contact hole forming method comprises steps of: applying a negative resist having an absorptivity of 0.5 .mu.m.sup.-1 or above to the stepped surface of a stepped film formed on a substrate to form a negative resist film having a flat surface; exposing the negative resist film through a photomask to laser light emitted by a krypton fluoride excimer laser; developing the exposed negative resist film; and etching the silicon dioxide film or the like by anisotropic etching using the developed negative resist film as an etching mask and an etching gas containing a fluorocarbon or a mixture of a fluorocarbon and hydrogen to form contact holes.

Abstract: An antireflective layer comprises a binder component in the form of a rosin which is soluble in both a low polar organic solvent and an aqueous alkaline solution, and a light absorbing component which is also soluble in both the low polar organic solvent and the aqueous alkaline solution. In photolithography, the antireflective layer exhibits excellent anti-reflective properties in a predetermine UV wavelength region, and, when used for forming resist patterns, the antireflective layer can be applied dissolved in the low polar organic solvent in a manner which has no detrimental effect on the resist, and can be removed along with the resist during the development process using the aqueous alkaline solution.
