Continuous chemical vapor deposition reactor

Claim 1

A continuous chemical vapor deposition reactor comprising: an elongated central core having a restricted opening at each end communicating to the outside atmosphere; a plurality of junction units interdisposed between said ends and dividing said elongated central core into a plurality of interconnected chambers comprising sealing chambers and substrate treating chambers and each unit having a restricted passageway therethrough aligned with and communicating adjacent ones of said chambers; a plurality of substrate carriers and spacers travelling into, through and out of said elongated central core; a plurality of viscous loss seals formed by means of the propinquity between said passageways and openings and said substrate carriers and spacers; said plurality of substrate carriers and spacers operatively associated with said elongated central core whereby to divide said core into a continuous elongated substrate treating and handling section comprised of said sealing and substrate treating chambers and a coextensive opposed section, said sections being isolated from each other; each of said junction units communicating with said opposed central core section and collectively providing means to subject adjacent isolated chamber portions comprising said opposed section to either an exhaust means or to a flush gas; and each of said junction units communicating with said substrate treating and handling core section and collectively providing means to subject adjacent isolated chamber portions comprising said treating and handling section with appropriate ones of sealing gases, substrate treatint gases and exhaust means; whereby all of the chamber sections are maintained isolated frome one another and from ingress of the atmosphere.
