Original Abstract Submitted
Described herein is a technique capable of suppressing sputtering on an inner peripheral surface of a process vessel when a process gas is plasma-excited in the process vessel. According to one aspect thereof, a substrate processing apparatus includes: a process vessel accommodating a process chamber where a process gas is excited into plasma; a gas supplier supplying the process gas into the process chamber; a coil wound around an outer peripheral surface of the process vessel and spaced apart therefrom, wherein a high frequency power is supplied to the coil; and an electrostatic shield disposed between the outer peripheral surface and the coil, wherein the electrostatic shield includes: a partition extending in a circumferential direction to partition between a part of the coil and the outer peripheral surface; and an opening extending in the circumferential direction and opened between another part of the coil and the outer peripheral surface.
