A radio frequency (RF) screen for a microwave powered ultraviolet (UV) lamp system is disclosed. In one example, a disclosed RF screen includes: a sheet comprising a conductive material; and a frame around edges of the sheet. The conductive material defines a predetermined mesh pattern of individual openings across substantially an operative area of the screen. Each of the individual openings has a triangular shape.

Radio frequency screen for an ultraviolet lamp system

An apparatus for fabricating a semiconductor device has a housing defining a buffer chamber, a plurality of reactor ports formed in the housing for establishing interfaces with a plurality of process chambers that are to receive a wafer during a fabrication process to fabricate the semiconductor device, a wafer positioning robot positioned within the buffer chamber to transport the wafer between the plurality of process chambers through the plurality of reactor ports, a purge port formed in the housing for introducing a purge gas into the buffer chamber, a pump port formed in the housing for exhausting a portion of the purge gas from the buffer chamber, and a first flow enhancer that directs the purge gas flowing in an axial direction along a longitudinal axis of the purge port into the buffer chamber in a plurality of radial directions relative to the longitudinal axis.

Semiconductor fabrication apparatus

Pumping liners for use in an apparatus for depositing a material on a work piece by chemical vapor deposition includes a plurality of unevenly spaced apertures are disclosed. Uneven spacing of the plurality of apertures produces a uniform flow of processing gases within a processing chamber with which the pumping liner is associated. Films of materials deposited onto a work piece by chemical vapor deposition techniques using disclosed pumping liners exhibit desirable properties such as uniform thickness and smooth and uniform surfaces.

CVD device pumping liner

A diffuser for diffusing a gas includes a base portion and a head portion fluidly coupled to the base portion. The head portion includes a diffuser element configured to diffuse a first fraction of the gas through a circumference of the diffuser element and a second fraction of the gas through an end surface of the diffuser element. The head portion further includes a connecting structure having a first connecting portion configured to receive a portion of the diffuser element therein and a second connecting portion protruding outwardly from the first connecting portion and configured to couple to the base portion.

Diffuser and semiconductor processing system using same

A humidity-controlled storage device includes a plurality of panels configured to form an enclosed volume. A first panel of the plurality of panels includes inlet and outlet ports. The storage device further includes a purge system with a gas inlet pipe, a gas supply system, and a gas extraction system. The gas inlet pipe includes a nozzle and a cylindrical portion coupled to the inlet port. The gas supply system is configured to supply a purge gas to the gas inlet pipe. The gas inlet pipe is configured to output the purge gas into the enclosed volume in a direction that creates a circular or an oval gas flow pattern within the enclosed volume. The gas extraction system is coupled to the outlet port and is configured to extract the purge gas from the enclosed volume.
