Plasma applications are disclosed that operate with argon and other molecular gases at atmospheric pressure, and at low temperatures, and with high concentrations of reactive species. The plasma apparatus and the enclosure that contains the plasma apparatus and the substrate are substantially free of particles, so that the substrate does not become contaminated with particles during processing. The plasma is developed through capacitive discharge without streamers or micro-arcs. The techniques can be employed to remove organic materials from a substrate, thereby cleaning the substrate; to activate the surfaces of materials, thereby enhancing bonding between the material and a second material; to etch thin films of materials from a substrate; and to deposit thin films and coatings onto a substrate; all of which processes are carried out without contaminating the surface of the substrate with substantial numbers of particles.

A reactor system comprises a process chamber, a gas inlet, and a dispenser. The dispenser is coupled to the gas inlet. The dispenser controls a gas flow from a vial to the gas inlet. The vial includes a coating material that, when released inside the process chamber under operating conditions of the reaction system, coats an inner wall of the process chamber.

The present inventive concept relates to a substrate processing device and a substrate processing method. The substrate processing device comprises: a chamber; a substrate support part rotatably installed in a process space inside the chamber so as to allow at least one substrate to be seated thereon; a first gas spray unit for spraying, to a first region of the process space, a source gas and a first purge gas for purging the source gas; a source gas supply source for supplying the source gas to the first gas spray unit; a first purge gas supply source for supplying the first purge gas to the first gas spray unit; a second gas spray unit spatially separated from the first region and configured to spray, to a second region of the process space, a reactant gas reacting with the source gas and a second purge gas for purging the reactant gas; a reactant gas supply source for supplying the reactant gas to the second gas spray unit; and a second purge gas supply source for supplying the second purge gas to the second gas spray unit.

A film-forming apparatus for forming a predetermined film on a substrate by plasma ALD includes a chamber, a stage, a shower head having an upper electrode and a shower plate insulated from the upper electrode, a first high-frequency power supply connected to the upper electrode, and a second high-frequency power supply connected to an electrode contained in the stage. A high-frequency power is supplied from the first high-frequency power supply to the upper electrode, thereby forming a high-frequency electric field between the upper electrode and the shower plate and generating a first capacitively coupled plasma. A high-frequency power is supplied from the second high-frequency power supply to the electrode, thereby forming a high-frequency electric field between the shower plate and the electrode in the stage and generating a second capacitively coupled plasma that is independent from the first capacitively coupled plasma.

Embodiments of the present disclosure provide a substrate processing system. In one embodiment, the system includes a chamber, a target disposed within the chamber, a magnetron disposed proximate the target, a pedestal disposed within the chamber, and a first gas injector disposed at a sidewall of the chamber, the first gas injector having a movable gas outlet.

A mounting table is provided. The mounting table includes an electrostatic chuck configured to mount thereon a target object and attract and hold the target object using an electrostatic force, and a gas supply line configured to supply a gas to a gap between the target object mounted on the electrostatic chuck and the electrostatic chuck via the electrostatic chuck. The mounting table further includes at least one irradiation unit configured to irradiate light having a predetermined wavelength to the gas flowing through the gas supply line or to the gas supplied to the gap between the target object and the electrostatic chuck to ionize the gas.

The present invention relates to a component for manufacturing a semiconductor manufactured by using a CVD method. A SiC structure formed by the CVD method according to one aspect of the present invention is used such that the SiC structure is exposed to plasma inside a chamber, wherein the SiC structure comprises a crystal grain structure in which the length in a first direction is longer than the length in a second direction when defining a direction perpendicular to the surface most exposed to the plasma as the first direction and a direction horizontal to the surface most exposed to the plasma as the second direction.

An exclusion ring for semiconductor wafer processing includes an outer circumferential segment having a first thickness and an inner circumferential segment having a second thickness, with the first thickness being greater than the second thickness. The top surface of an inner circumferential segment and the top surface of the outer circumferential segment define a common top surface for the exclusion ring. A plurality of flow paths is formed within the outer circumferential segment, with each of the flow paths extending radially through the plurality of flow paths provides for exhaust of a wafer edge gas from the pocket where a wafer has an edge thereof disposed below part of the inner circumferential portion. The exhausting of the wafer edge gas from the pocket prevents up-and-down movement of the exclusion ring when bowed wafers are processed.

Showerheads for semiconductor processing equipment are disclosed that include various features designed to reduce nonuniformity and adjust deposited film profiles.

A plasma-generating nozzle and a plasma device including the plasma-generating nozzle are provided. The plasma-generating nozzle includes a plasma-generating channel, a cooling channel at least partially surrounding the plasma-generating channel, and a pair of electrodes partially disposed in the plasma-generating channel for generating plasma. The plasma device includes a housing enclosing a plasma treatment space and a component space, and the plasma-generating nozzle removable disposed in the plasma treatment space.
