摘要： A plasma etching device which has an auxiliary electrode enabling realization of a uniform plasma density of generated plasma on the surface of a base and which enables uniform etching with respect to the base without depending upon pressure and without rotating a magnetic field applying means. The plasma etching device has magnetic field applying means which has two parallel plate electrodes I and II and RF power applying means, with the base set on the electrode I, and which is horizontal and unidirectional with respect to the surface of the base where plasma etching is carried out. In this plasma etching device, an auxiliary electrode is provided at least on the upstream side of the base in a flow of electron current generated by the magnetic field applying means. The auxiliary electrode includes a local electrode arranged on the side facing the electrode II and means for adjusting impedance provided at a part of the local electrode to be electrically connected with the electrode I.
