An object is to provide a semiconductor device of which a manufacturing process is not complicated and by which cost can be suppressed, by forming a thin film transistor using an oxide semiconductor film typified by zinc oxide, and a manufacturing method thereof. For the semiconductor device, a gate electrode is formed over a substrate; a gate insulating film is formed covering the gate electrode; an oxide semiconductor film is formed over the gate insulating film; and a first conductive film and a second conductive film are formed over the oxide semiconductor film. The oxide semiconductor film has at least a crystallized region in a channel region.

Semiconductor device, and manufacturing method thereof

A faceplate for a showerhead of a semiconductor wafer processing system is provided. The faceplate has a plurality of gas passageways to provide a plurality of gases to the process region without commingling those gases before they reach the processing region within a reaction chamber. The showerhead includes a faceplate and a gas distribution manifold assembly. The faceplate defines a plurality of first gas holes that carry a first gas from the manifold assembly through the faceplate to the process region, and a plurality of channels that couple a plurality of second gas holes to a radial plenum that receives the second gas from the manifold assembly. The faceplate and the manifold assembly are each fabricated from a substantially solid nickel material.

Dual gas faceplate for a showerhead in a semiconductor wafer processing system

Embodiments of the invention provide an apparatus configured to form a material during an atomic layer deposition (ALD) process, such as a plasma-enhanced ALD (PE-ALD) process. In one embodiment, a lid assembly for conducting a vapor deposition process within a process chamber is provided which includes an insulation cap and a plasma screen. In one example, the insulation cap has a centralized channel configured to flow a first process gas from an upper surface to an expanded channel and an outer channel configured to flow a second process gas from an upper surface to a groove which is encircling the expanded channel. In one example, the plasma screen has an upper surface containing an inner area with a plurality of holes and an outer area with a plurality of slots. The insulation cap may be positioned on top of the plasma screen to form a centralized gas region with the expanded channel and a circular gas region with the groove.

Apparatus and process for plasma-enhanced atomic layer deposition

Embodiments of the invention provide methods for depositing a capping layer on a dielectric layer disposed on a substrate. In one example, a process includes exposing a substrate to a deposition process to form a dielectric layer thereon, exposing the substrate to sequential pulses of a silicon precursor and an oxidizing gas to form a silicon-containing layer on the dielectric layer during a deposition process, exposing the substrate to a nitridation process to form a capping layer thereon and exposing the substrate to an annealing process for a predetermined time. The capping layer may a thickness of about 5 A or less. In one example, the oxidizing gas contains water vapor derived from a hydrogen source gas and an oxygen source gas processed by a water vapor generator containing a catalyst. In another example, the deposition, nitridation and annealing processes occur in the same process chamber.

In one embodiment, a method for forming a dielectric material is provided which includes exposing a substrate sequentially to a metal-containing precursor and an oxidizing gas to form metal oxide (e.g., HfO x ) during an ALD process and subsequently exposing the substrate to an inert plasma process and a thermal annealing process. Generally, the metal oxide contains hafnium, tantalum, titanium, aluminum, zirconium, lanthanum or combinations thereof. In one example, the inert plasma process contains argon and is free of nitrogen, while the thermal annealing process contains oxygen. In another example, an ALD process to form a metal oxide includes exposing the substrate sequentially to a metal precursor and an oxidizing gas containing water vapor formed by a catalytic water vapor generator. In an alternative embodiment, a method for forming a dielectric material is provide which includes exposing a substrate to a deposition process to form a metal oxide layer and subsequently exposing the substrate to a nitridation plasma process and a thermal annealing process to form metal oxynitride (e.g., HfO x N y ).

Plasma treatment of hafnium-containing materials

An apparatus for measuring the temperature of a substrate in a thermal processing chamber. The substrate is suspended above a reflector to form a reflecting cavity. A probe of a temperature sensor has an input end positioned to receive radiation from the reflecting cavity and an output end optically coupled to a detector to provide a temperature reading. The temperature sensor is configured to reduce the effect that radiation which has an axis of propagation within an angle of an axis normal to the reflector, e.g., substantially normal radiation from a portion of the substrate adjacent to the input end of the probe, has on the temperature reading.

An apparatus and method for exposing a substrate to plasma including a first reaction chamber (300) adapted to generate a plasma comprising ions and radicals and a second reaction chamber (200) coupled to the first reaction chamber and adapted to house a substrate at (100). The second reaction chamber is coupled to the first reaction chamber by an inlet member (275) and radicals of the plasma flow through the inlet member into the second reaction chamber.

Apparatus and method for exposing a substrate to plasma radicals

A method of forming an oxide on a substrate. According to the method of the present invention a substrate is placed in a chamber. An oxygen containing gas and a hydrogen containing gas are then fed into the chamber. The oxygen containing gas and the hydrogen containing gas are then caused to react with one another to form water vapor in the chamber. The water vapor then oxidizes the substrate.

Method and apparatus for insitu vapor generation

A system and method of forming an oxide in the presence of a nitrogen-containing material. A substrate having a nitrogen-containing material on a surface is placed in a reaction chamber. An oxygen-containing gas, or an oxygen-containing gas and a hydrogen-containing gas are provided to the chamber and reacted in the chamber. The reactive gases are used to oxidize the surface of the substrate and displace the nitrogen-containing material from the interface.
