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.

Techniques are disclosed for roll-to-roll (R2R) atomic layer deposition (ALD). R2R ALD is accomplished by arranging precursor nozzles in A/B pairs while a flexible web substrate moves underneath the A/B pairs at a uniform speed. Nozzles A of the A/B pairs continuously flow a precursor A into the process volume of the R2R ALD chamber. The plasma enhanced/activated ALD (PEALD/PAALD) embodiments utilize electron cyclotron rotation (ECR)-enhanced hollow cathode plasma sources (HCPS) where nozzles B flow activated neutrals of precursor B into the process volume. As the flexible web moves in an R2R motion, nucleates from precursor A deposited on the surface of the substrate, and neutrals of precursor B undergo a self-limiting reaction to deposit a single atomically sized ALD film/layer. In this manner, multiple ALD layers may be deposited by each successive A/B pair in a single pass of the web. There is also a heat source underneath the web to further facilitate the ALD reaction, or to support thermal ALD embodiments.

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.

Provided is a method of producing a copper-containing layer, including: step 1: a step of reducing a surface of a substrate, provided that a substrate having a surface formed of a silicic acid compound is excluded, through use of a reducing agent; and step 2: a step of forming a copper-containing layer on the surface having been reduced in the step 1 through use of a thin-film forming raw material containing a copper compound by a plasma atomic layer deposition method.

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.

An impedance measurement jig may include a first contact plate, a second contact plate, a cover plate, a plug, and an analyzer. The first contact plate may make electrical contact with an ESC in a substrate-processing apparatus. The second contact plate may make electrical contact with a focus ring configured to surround the ESC. The cover plate may be configured to cover an upper surface of the substrate-processing apparatus. The plug may be installed at the cover plate to selectively make contact with the first contact plate or the second contact plate. The analyzer may individually apply a power to the first contact plate and the second contact plate through the plug to measure an impedance of the ESC and an impedance of the focus ring. Thus, the impedances of the ESC and the focus ring may be individually measured to inspect the ESC and/or the focus ring.

Provided are apparatuses and methods for performing deposition and etch processes in an integrated tool. An apparatus may include a plasma processing chamber that is a capacitively-coupled plasma reactor, and the plasma processing chamber can include a showerhead that includes a top electrode and a pedestal that includes a bottom electrode. The apparatus may be configured with an RF hardware configuration so that an RF generator may power the top electrode in a deposition mode and power the bottom electrode in an etch mode. In some implementations, the apparatus can include one or more switches so that at least an HFRF generator is electrically connected to the showerhead in a deposition mode, and the HFRF generator and an LFRF generator is electrically connected to the pedestal and the showerhead is grounded in the etch mode.

Forming a protective coating ex situ in an atomic layer deposition process to coat one or more chamber components subsequently installed in a reaction chamber provides a number of benefits over more conventional coating methods such as in situ deposition of an undercoat. In certain cases the protective coating may have a particular composition such as aluminum oxide, aluminum fluoride, aluminum nitride, yttrium oxide, and/or yttrium fluoride. The protective coating may help reduce contamination on wafers processed using the coated chamber component. Further, the protective coating may act to stabilize the processing conditions within the reaction chamber, thereby achieving very stable/uniform processing results over the course of processing many batches of wafers, and minimizing radical loss. Also described are a number of techniques that may be used to restore the protective coating after the coated chamber component is used to process semiconductor wafers.

Methods of depositing a nanocrystalline diamond film are described. The method may be used in the manufacture of integrated circuits. Methods include treating a substrate with a mild plasma to form a treated substrate surface, incubating the treated substrate with a carbon-rich weak plasma to nucleate diamond particles on the treated substrate surface, followed by treating the substrate with a strong plasma to form a nanocrystalline diamond film.
