Actuator to adjust dynamically showerhead tilt in a semiconductor-processing apparatus
In various embodiments, a showerhead mechanism to adjust a showerhead in a semiconductor substrate-processing apparatus is disclosed. The mechanism includes at least one actuator assembly that is dynamically operable to adjust parallelism of a faceplate of the showerhead with reference to an upper surface of a substrate pedestal that is to be positioned adjacent to the faceplate. Each of the actuator assemblies includes a piezoelectric stack and a lever having a first end and a second end. The lever is mechanically coupled on the first end to the piezoelectric stack and on the second end to the showerhead to displace the showerhead in at least one direction of tilt. The lever is operable to amplify mechanically a displacement of the piezoelectric stack. A lever pivot point is coupled to the lever and is located between the first end and the second end of the lever.
Apparatus and methods for controlling concentration of precursors to processing chamber
Apparatus and methods for supplying a vapor to a processing chamber are described. The vapor delivery apparatus comprises an inlet conduit and an outlet conduit, each with two valves, in fluid communication with an ampoule. A bypass conduit connects the inlet conduit and the outlet conduit. A flow restrictive device restricts flow through the outlet conduit.
APPARATUS FOR CONDUCTING PLASMA SURFACE TREATMENT, BOARD TREATMENT SYSTEM HAVING THE SAME, AND METHOD OF MANUFACTURING SEMICONDUCTOR DEVICES USING THE SAME
A surface treatment apparatus and a surface treatment system having the same are disclosed. The surface treatment apparatus includes a process chamber in which the surface treatment process is conducted, a plasma generator for generating process radicals as a plasma state for the surface treatment process, the plasma generator being positioned outside of the process chamber and connected to the process chamber by a supply duct, a heat exchanger arranged on the supply duct and cooling down temperature of the process radicals passing through the supply duct and a flow controller controlling the process radicals to flow out of the process chamber. The flow controller is connected to a discharge duct through which the process radicals are discharged outside the process chamber. The plasma surface treatment process is conducted to the package structure having minute mounting gap without the damages to the IC chip and the board.
Plasma processing apparatus
A plasma processing apparatus includes a baffle structure between a mounting table and a processing chamber. The baffle structure has a first member and a second member. The first member has a first cylindrical part extending between the mounting table and the processing chamber, and a plurality of through-holes elongated in the vertical direction is formed in an array in the circumferential direction in the first cylindrical part. The second member has a second cylindrical part having an inner diameter greater than the outer diameter of the cylindrical part for the first member. The second member moves up and down in a region that includes the space between the first member and the processing chamber.
ALD APPARATUS, METHOD AND VALVE
An apparatus, a method and a valve with a reactive chemical inlet, a reaction chamber outlet, and a closure having an open and closed configuration to open and close, respectively, a route from the reactive chemical inlet to the reaction chamber outlet, the valve further including an additional cleaning chemical inlet at a downstream side of the closure to purge the closure.
Vacuum systems in semiconductor fabrication facilities
Methods and devices are provided wherein rotational gas-flow is generated by vortex generators to decontaminate dirty gas (e.g., gas contaminated by solid particles) in pumping lines of vacuum systems suitable for use at a semiconductor integrated circuit fabrication facility. The vacuum systems use filterless particle decontamination units wherein rotational gas-flow is applied to separate and trap solid particles from gas prior to the gas-flow entering a vacuum pump. Methods are also described whereby solid deposits along portions of pumping lines may be dislodged and removed and portions of pumping lines may be self-cleaning.
Apparatus and methods for improving chemical utilization rate in deposition process
Processing chambers and methods to disrupt the boundary layer are described. The processing chamber includes a showerhead and a substrate support therein. The showerhead and the substrate support are spaced to have a process gap between them. In use, a boundary layer is formed adjacent to the substrate support or wafer surface. As the reaction occurs at the wafer surface, reaction products and byproduct are produced, resulting in reduced chemical utilization rate. The processing chamber and methods described disrupt the boundary layer by changing one or more process parameters (e.g., pressure, flow rate, time, process gap or temperature of fluid passing through the showerhead).
SUBSTRATE PROCESSING APPARATUS
Provided is a reactor capable of improving the symmetry of the profile of a thin film deposited on a substrate with an asymmetric exhaust structure, wherein a distance between a gas flow control ring (FCR) and an exhaust unit on one side where an exhaust port is located is greater than a distance between the FCR and the exhaust unit on the opposite side of the exhaust port.
