PROCESS CHAMBER AND CAPACITIVELY COUPLED PLASMA APPARATUS

Номер: WO2019062573A1
Автор: WANG, Wenzhang, CHEN, Peng, DING, Peijun, LIU, Feifei
Принадлежит:

Provided are a process chamber and a capacitively coupled plasma apparatus. The process chamber comprises a chamber body, a lining, and a magnetic assembly, wherein the lining is arranged inside the chamber body and defines and forms a process area for processing a wafer; and the magnetic assembly is arranged outside the process area, and a magnetic field generated by the magnetic assembly can narrow the gap between the etching rate of a peripheral area of the wafer and the etching rate of a central area thereof during the processing process of the wafer.

Provided are a Faraday shield and a reaction chamber, comprising a conductive ring body, wherein a slit is formed on the conductive ring body; in the developed view of the conductive ring body, the length of a projection, in the axial direction of the conductive ring body, of the slit is greater than zero; and the length of a projection, on the circumference of the conductive ring body, of the slit is greater than zero, so as to increase the total coupling efficiency of an electromagnetic field by means of increasing the coupling efficiency of an electric field component, in the circumferential direction of the conductive ring, of the electromagnetic field. The Faraday shield and the reaction chamber provided in the present invention can improve the coupling efficiency of a magnetic field, so that radio frequency power needing to be loaded onto a radio frequency coil can be reduced.
