Patent number: 5344536Abstract: An electron cyclotron resonance plasma chemical vapor deposition system has a reaction chamber for introducing a reaction gas therein, the reaction chamber housing a table for supporting a semiconductor wafer. A microwave oscillator is connected to the reaction chamber through a waveguide for generating and introducing a microwave into the reaction chamber to produce a plasma in the reaction chamber for activating the reaction gas to etch or deposit a film on the semiconductor wafer in the reaction chamber. A pair of upper and lower coils is disposed around the reaction chamber for generating respective magnetic fields in opposite directions in the reaction chamber. The magnetic fields cancel out each other creating a region with substantially no flux density in the magnetic fields between the coils. A bias voltage is applied to the table to attract the plasma to the table in a uniform manner.Type: GrantFiled: December 2, 1992Date of Patent: September 6, 1994Assignee: Tokyo Ohka Kogyo Co., Ltd.Inventors: Kazuto Obuchi, Satoshi Oya, Mitsuaki Minato, Akira Uehara, Kazutoshi Fujisawa, Kazuhisa Takao
