Abstract
A layer formation method is disclosed which comprises supplying gas to a discharge space, exciting the supplied gas at atmospheric pressure or at approximately atmospheric pressure by applying a high frequency electric field across the discharge space, and exposing a substrate to the excited gas, wherein the high frequency electric field is an electric field in which a first high frequency electric field and a second high frequency electric field are superposed, frequency &ohgr; of the second high frequency electric field is higher than frequency &ohgr; of the first high frequency electric field, strength V of the first high frequency electric field, strength V of the second high frequency electric field and strength IV of discharge starting electric field satisfy relationship V ≧IV>V or V >IV≧V , and power density of the second high frequency electric field is not less than 1 W/cm .
