Abstract

A method for producing a thin semiconductor film according to the present invention includes the steps of: placing a group-IV compound or a derivative thereof in a plasma state; decomposing the group-IV compound or the derivative thereof into active species; and depositing the active species on a substrate, wherein energy for generating plasma is intermittently supplied at a supply time interval which is equal to or less than a reciprocal of {(secondary reaction rate constant of a source gas reacting with active species other than long-life active species within the plasma).times.(number of source gas molecules)}.
