Abstract:
1. A plasma excitation module, comprising: a chamber, having a single dielectric layer; a plurality of coils, disposed at an outer side of the dielectric layer of the chamber, wherein the coils are disposed in parallel connection; and a multi-duct gas intake system, surrounding the dielectric layer and communicated with the chamber, wherein a normal direction of the coils is perpendicular to a gas intake direction of the multi-duct gas intake system, wherein the multi-duct gas intake system comprises: a gas intake duct, comprising: a main duct; and a plurality of branch ducts, connecting the main duct; a gas intake interface, connecting the gas intake duct, wherein the gas intake interface is disposed between the dielectric layer and the chamber; and a plurality of nozzles, disposed in the gas intake interface to make the gas intake duct communicated with the chamber, wherein an outlet end of each of the branch ducts is connected to each of the nozzles, wherein the branch ducts comprises: four first branches, connecting the main duct; and a plurality of second branches, third branches until N-th branches, wherein N is a positive integer less than 1000, each of the second branches connects an outlet end of each respective first branch and an inlet end of each respective third branch, each of the (N−1)-th branches connects an outlet end of each respective (N−2)-th branch and an inlet end of each respective N-th branch and each of the N-th branches connects an outlet end of each respective (N−1)-th branch and each respective nozzle, wherein N is a positive integer, wherein each first branch connects to two second branches, each second branch connects to two third branches, and each of the (N−1)-th branches connects to two N-th branches.
