Abstract

A plasma process and an apparatus therefor are described. A number of substrates are disposed between a pair of electrodes, to which a high frequency electric power is applied in order to generate glow discharge and induce a plasma. The substrates in the plasma are applied with an alternating electric field. By virtue of the alternating electric field, the substrates are subjected to sputtering action.
