A gas collector is disclosed for use with epitaxial reactors. The gas collector is in the form of a base and top portion that are interconnected by means of a sealing arrangement. The top portion is configured to cover the base and define a conduit therebetween. Inlets and outlets are provided to direct chemical vapors from a reaction chamber of the epitaxial reactor into the conduit and further into an exhaust pipe of the epitaxial reactor. The gas collector is capable of forming a hermetic seal with the lid of the reaction chamber in order to prevent escape of chemical vapors.

An image intensifier tube includes a microchannel plate (MCP) having conductive input and output surfaces disposed in a housing. A conductive lower support is in electrical contact with the output surface of the MCP, and a conductive upper support is disposed above the input surface of the MCP. A shape memory alloy (SMA) lockdown is disposed between the input surface of the MCP and the upper support. The SMA lockdown is configured to provide a lockdown for the MCP in the housing. An SMA upper surface is configured to provide an axial force against the upper support, and an SMA lower surface is in contact with the input surface of the MCP.

摘要:
A gas collector for collecting gasses from within a reaction chamber of a reactor comprises a rigid body having a conduit, inlets, an outlet, and a seal disposed on the body. The seal cooperates with a lid of the reactor to prevent escape of reaction gasses from the reaction chamber. The inlets direct the gasses from the reaction chamber into the conduit, and the outlet exhausts the gasses from the conduit. The body includes a first member and a second member with the seal disposed on the second member. The body can include inter-member seals for reducing the flow of the gasses across an interface between the first member and the second member. The inter-member seals disposed between the first member and the second member and allow movement of the first member relative to the second member. The body can also be formed from graphite and can also shape the flow of gasses into the reaction chamber to prevent the formation of standing eddy currents adjacent the gas collector. A method of manufacturing a semiconductor device with the gas collector is also disclosed.

A gas collector for collecting gasses from within a reaction chamber of a reactor comprises a body having a conduit, at least one inlet, an outlet, and a seal disposed on the body. The seal cooperates with a lid of the reactor to prevent escape of reaction gasses from the reaction chamber. The body includes first and second members and is formed from graphite. The seal is formed from molybdenum and is ring-shaped with a generally crescent-shaped cross-section and inner and outer edges. A top surface of the body includes a pair of concentric slots into which the inner and outer edges are respectively positioned. The first and second members can be detachably connected to one another, and the first and second members can be stationary relative to one another during operation of the gas collector.

A gas collector for collecting gasses from within a reaction chamber of a reactor comprises a body having a conduit, at least one inlet, an outlet, and a seal disposed on the body. The seal cooperates with a lid of the reactor to prevent escape of reaction gasses from the reaction chamber. The inlets direct the gasses from the reaction chamber into the conduit, and the outlet exhausts the gasses from the conduit. The gas collector includes means for providing an even flow of gasses through the reaction chamber. The body includes a first member and a second member with the seal disposed on the second member. The body can include inter-member seals for reducing the flow of the gasses across an interface between the first member and the second member. The inter-member seals disposed between the first member and the second member and allow movement of the first member relative to the second member. The body can also be formed from graphite.
