Gas collector for epitaxial reactor

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.
