Abstract:
A semiconductor substrate processing chamber and substrate transfer chamber interfacial structure, comprising:a body sized and shaped to engage with and between a semiconductor substrate processing chamber and a substrate transfer chamber effective to space the processing chamber and transfer chamber away from one another; the body comprising a substrate passageway extending therethrough, the passageway comprising walls at least a portion of which are substantially metallic; the body comprising material peripheral of the walls which is substantially non-metallic and thermally insulative, the substantially non-metallic material comprising mounting openings extending at least partially therein; and the body comprising a plurality of openings spaced from the passageway and which extend through the insulative material, and comprising load bearing plugs received within at least some of the openings in the thermally insulative material, the load bearing plugs having greater compression strength than the thermally insulative material, at least some of the load bearing plugs comprising holes extending therethrough which are sized to receive mounting bolts, at least some of the load bearing plugs being entirely solid.
