Abstract: A film forming apparatus for forming films on substrates mounted on a rotary table by rotating the rotary table and causing the substrates to sequentially pass through areas to which process gases are supplied, including: recess portions formed in one surface of the rotary table along a circumferential direction and configured to accommodate the substrates; mounting portions disposed with the recess portions and configured to support regions of the substrates closer to centers than peripheral edge portions thereof; groove portions formed within the recess portions so as to surround the mounting portions; communication paths formed so as to extend from regions of the groove portions existing at a side of a rotational center of the rotary table toward an external area of the recess portions; and an exhaust port through which an interior of a vacuum container is vacuum-exhausted.

Abstract: There is provided a substrate warping monitoring device for monitoring a warping of a substrate mounted in a substrate mounting region formed in a rotary table along a circumferential direction during rotation of the rotary table, including: an optical displacement meter located above the rotary table and configured to irradiate a light to a predetermined position on the rotary table, receive a reflected light reflected off the rotary table and the substrate which passes through the predetermined position and measure a surface profile of the substrate; a memory part configured to store a measurement value acquired when the light is irradiated on a predetermined reference surface, as a reference value; and a calculation part configured to calculate a warping amount of the substrate based on the surface profile of the substrate measured by the optical displacement meter and the reference value stored in the memory part.

Abstract: A substrate warpage detection device for detecting warpage of a substrate loaded on a substrate loading region having a recess shape formed on a rotary table along a circumferential direction during rotation of the rotary table, includes a light transmitting part configured to transmit a light beam obliquely upward from a side of the rotary table such that a lower portion of the light beam collides with an upper end of a side surface of the rotary table and an upper portion of the light beam positioned more upward than the lower portion of the light beam passes a portion near the surface of the rotary table, and a light receiving part installed to face the light transmitting part and configured to receive the light beam passing the portion near the surface of the rotary table so as to detect an amount of received light.

Abstract: A substrate processing apparatus includes a first hole portion formed through a sidewall of the process chamber and horizontally extending outward and a second hole portion formed to be contiguous with the first hole portion and defining a supply channel for a process gas. The apparatus also includes a gas nozzle, a plurality of seal members and an annular spacer. A proximal end of the gas nozzle is inserted into the first hole portion. The plurality of seal members is spaced apart from each other between an outer circumferential surface of the gas nozzle and the first hole portion. The annular spacer is inserted into the first hole portion and is pressed against an annular surface of an opening periphery of the second hole portion by the gas nozzle in a state where the proximal end of the gas nozzle is engaged with the annular spacer.
