Claim 10:
11. A method of manufacturing a semiconductor device comprising:
(a) loading a substrate into a process chamber provided in a process vessel;
(b) supplying a process gas to the process chamber;
(c) plasma-exciting the process gas supplied into the process chamber by supplying a high frequency power to a coil wound around an outer peripheral surface of the process vessel while being spaced apart from the outer peripheral surface; and
(d) processing the substrate by the process gas plasma-excited,
wherein an electrostatic shield disposed between the outer peripheral surface of the process vessel and the coil is used in (c), the electrostatic shield comprising:
a partition extending in a circumferential direction of the coil and configured to partition between a part of the coil and the outer peripheral surface of the process vessel; and
an opening extending in the circumferential direction of the coil and opened between another part of the coil and the outer peripheral surface of the process vessel.
