Title: Electromagnetic coupling rf plasma reactor having solenoid antenna in upper part
Inventor: COLLINS KENNETH S
IPC: H01L21/683
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To lower the height of a ceiling board without deteriorating the processing uniformity by increasing the product of electric current and the number of turns of a coil near the center axis of a tank in the case the plasma ion density is the lowest in the height between a short processing object and a ceiling board. SOLUTION: A cylindrical tank 40 has a non-flat coil antenna 42 and the windings 44 of the antenna are densely concentrated near the antenna symmetric axis 46 in a non-flat manner. By making the winding 44 symmetric, empty parts of the radiation pattern are formed near the symmetric axis 46 of the antenna in which the center of the tank and the center of the processing object are mutually conformed. The windings 44 are densely concentrated on the surrounding of the center axis 46 and to compensate the empty parts, a solenoid pattern in which respective solenoids are kept from the tank center axis 46 at the shortest distance is employed and windings 44 are layered vertically.  Consequently, in the case plasma ion density is the weakest in a height between a short processing object and the ceiling boards, the product of the electric current and the number of turns of the coil is increased near the tank center axis 46. As a result, without deteriorating the uniformity of processing, the height of the ceiling board can be lowered in order to heighten the plasma processing function.
