Patent JP-H06291085-A (JP)
Title: Control method of plasma
Inventor: MORI HIDEKI
IPC: H05H1/46
Filed: 1993-03-31
Abstract: PURPOSE:To effectively prevent the occurrence of gate breakdown, by a method wherein plasma density is increased by applying a magnetic field to plasma from an electromagnet while etching progresses, and the electromagnet is controlled so as to decrease the intensity of the magnetic field before etching ends. CONSTITUTION:When a magnetic field is applied to plasma P by using a magnetic pole 12 and a mangetic pole 13 of an electromagnet while etching progresses, the plasma densely gathers in the travelling direction of electrons in an electric field, so that the density of one side is increased and bias is generated in the plasma P. When the magnetic field intensity is decreased before the etching ends, the density of the plasma P is decreased, and the plasma the bias has been generated during the etching is made uniform. Hence potential difference is not generated in the electric field, so that an excess current can be effectively prevented from flowing in an aluminum film 4a of a wafer 4. Thereby the aluminum film 4b of the wafer 4 is not damaged and gate breakdown can be effectively prevented.
