ABSTRACT:
An equipment for manufacturing semiconductor devices has: a reaction chamber in which a substrate to be processed is placed; means for evacuating the reaction chamber; means for introducing a reaction gas into the reaction chamber; means for applying polarized light to the surface of the substrate for the purpose of depositing a thin film on the surface of the substrate using a photochemical reaction between the light and the reaction gas; and means for adjusting the direction of polarization of the light so as to be substantially perpendicular to the longitudinal axis of a stepped circuit pattern present on the surface of the substrate for the purpose of flattening the circuit pattern.
