Title: Plasma processing equipment and plasma processing method using the equipment
Inventor: KUBOTA SHINJI
IPC: C23F4/00
Filed: 1994-07-08
Abstract: PURPOSE:To improve uniformity of etching rate on the same plane by a parallel plane RIE equipment or a magnetron RIE equipment. CONSTITUTION:A compound anode 10 formed by flattening the periphery of a dome part 3a of a conductive dome anode 3 by using insulator 9 is applied to the facing electrode to a cathode 10. In the case of ion mode etching, the etching rate at the center part of a wafer W is increased by a high field intensity just under the dome part 3a, so that the decrease of discharge speed of reaction product in the center part is chanceled. Since the substrate surface of the compound anode 10 is flattened and the wafer W comes into contact with plasma P of nearly uniform volume, etching progresses uniformly at the time of radical mode etching. The same RIE equipment can cope excellently with both contact hole etching and LOCOS SiN etching.
