A showerhead including a body having an opening, a first plate positioned within the opening and having a plurality of slots, a second plate positioned within the opening and having a plurality of slots, and wherein each of the first plate plurality of slots are concentrically aligned with the second plate plurality of slots.

Semiconductor reaction chamber showerhead

A gas inlet system for a wafer processing reactor includes a tubular gas manifold conduit adapted to be connected to a gas inlet port of the wafer processing reactor; and gas feeds including a first feed for feeding a first gas into the tubular gas manifold conduit and a second feed for feeding a second gas into the tubular gas manifold conduit. Each feed has two or more injection ports connected to the tubular gas manifold conduit at a first axial position of the tubular gas manifold conduit, and the injection ports of each of the gas feeds are evenly distributed along a circumference of the tubular gas manifold conduit at the first axial position.

Gas Supply Manifold And Method Of Supplying Gases To Chamber Using Same

A gas distribution system, a reactor system including the gas distribution system, and method of using the gas distribution system and reactor system are disclosed. The gas distribution system can be used in gas-phase reactor systems to independently fine tune gas source locations and gas flow rates of reactants to a reaction chamber of the reactor systems.

An improved exhaust system for a gas-phase reactor and a reactor and system including the exhaust system are disclosed. The exhaust system includes a channel fluidly coupled to an exhaust plenum. The improved exhaust system allows operation of a gas-phase reactor with desired flow characteristics while taking up relatively little space within a reaction chamber.

Gas-phase reactor and system having exhaust plenum and components thereof

A system and method for providing intermediate reactive species to a reaction chamber are disclosed. The system includes an intermediate reactive species formation chamber fluidly coupled to the reaction chamber to provide intermediate reactive species to the reaction chamber. A pressure control device can be used to control an operating pressure of the intermediate reactive species formation chamber, and a heater can be used to heat the intermediate reactive species formation chamber to a desired temperature.

Method and system for in situ formation of gas-phase compounds

Nanostructured photonic materials and associated components for use in devices and systems operating at ultraviolet (UV), extreme ultraviolet (EUV), and/or soft Xray wavelengths are described. Such a material may be fabricated with nanoscale features tailored for a selected wavelength range, such as at particular UV, EUV, or soft Xray wavelengths or wavelength ranges. Such a material may be used to make components such as mirrors, lenses or other optics, panels, lightsources, masks, photoresists, or other components for use in applications such as lithography, wafer patterning, biomedical applications, or other applications.
