    Abstract: The apparatus includes a process chamber having a treating space therein, a support unit for supporting the substrate in the treating space, a gas supply unit for supplying treating gas to the treating space, and a microwave application unit for applying microwaves to the treating gas to generate plasma. The microwave application unit may include first power supply for applying a first microwave, a support plate having a groove formed on an upper surface thereof and combined with the process chamber above the support unit to define the treating space, a first transmission plate inserted into the groove to radiate the first microwave to the treating space, and a first waveguide disposed to overlap with an upper portion of the first transmission plate and coupled to the first power supply, wherein a plurality of grooves may be formed along a circumferential direction in an edge region of the support plate.

    Abstract: A plasma processing apparatus includes a processing container including an opening provided in a ceiling wall of the processing container, and a microwave radiation source. The microwave radiation source includes a slot antenna including a slot and configured to radiate microwaves from the slot, and a transmission window configured to close the opening and to radiate the microwaves from the slot into the processing container. The transmission window includes a first surface including a skirt which suspends to cover a side wall of the opening, and a second surface which is an opposite surface to the first surface and faces the slot antenna with a gap between the slot antenna and the second surface.

    Abstract: A microwave control method is used in a microwave plasma processing apparatus including a microwave generation unit, a waveguide for guiding a microwave generated by the microwave generation unit, a tuner for controlling a position of a movable short-circuiting plate, and a stub provided between the tuner and an antenna in the waveguide and insertable into an inner space of the waveguide. The method incudes detecting the position of the movable short-circuiting plate controlled by the tuner for the microwave outputted by the microwave generation unit, determining whether or not a difference between a reference position and the detected position of the movable short-circuiting plate is within a tolerable range, and controlling an insertion length of the stub into the inner space of the waveguide when it is determined that the difference between the position of the movable short-circuiting plate and the reference position is not within the tolerable range.

    Abstract: This microwave plasma processing apparatus has, as a gas introduction mechanism for introducing a working gas inside a chamber (10), electrical discharge prevention members (96(1) to 96(8)), each of which is provided to a plurality of dielectric window gas passages (94(1) to (94(8)) through which a dielectric window (54) passes. Each electrical discharge prevention member (96(n)), a portion (114) of which protrudes only a height h, which is greater than or equal to a predetermined distance H, upward from the rear surface of a dielectric window (52) on the inlet side, passes through an opening (54a) of a slot plate (54), and inserts into a branched gas supply path (92(n)) of a gas branch part (90). The gas branch part (90), spring coils (116) and the slot plate (54), which surround the protruding portion (114) of each electrical discharge prevention member (96(n)), constitute an enclosing conductor (118).

    Abstract: The microwave plasma processing apparatus includes a power feeding rod that applies high frequency wave for RF bias, the upper end of which is connected to a susceptor, and the lower end of which is connected to a high frequency output terminal of a matcher in a matching unit; a cylindrical external conductor that encloses around the power feeding rod serving as an internal conductor; and a coaxial line. The coaxial line is installed with a choke mechanism configured to block undesired microwave that enters the line from a plasma producing space in a chamber, and leakage of the microwave to an RF feeding line is prevented in the middle of the line, thereby suppressing the microwave leakage.

    Abstract: A microwave emission mechanism includes: a transmission path through which a microwave is transmitted; and an antenna section that emits into a chamber the microwave transmitted through the transmission path. The antenna section includes an antenna having a slot through which the microwave is emitted, a dielectric member through which the microwave emitted from the antenna is transmitted and a closed circuit in which a surface current and a displacement current flow. A surface wave is formed in a surface of the dielectric member. The closed circuit has at least: an inner wall of the slot; and the surface and an inner portion of the dielectric member. When a wavelength of the microwave is λ0, a length of the closed circuit is nλ0±δ, where n is a positive integer and δ is a fine-tuning component including 0.
