Abstract:
1. A method of chemical vapor deposition of layers of material on substrates for producing semiconductor devices, comprising the steps of: continuously conveying a plurality of substrates through a plurality of in-line deposition regions; continuously providing and distributing a chemical vapor at each said region to deposit material for the layers, including, delivering chemical materials to a first plenum in a first plenum layer and to a second plenum in a second plenum layer, said chemical materials separated between said plenums, said separated chemical materials capable of reacting when not separated, delivering chemical materials from said first and second plenums to a third plenum layer and maintaining said separation in said third plenum layer, said delivery of chemical materials from said first plenum to said third plenum layer including passing chemical materials from said first plenum through said second plenum layer, and emitting and distributing said separated chemical materials from said third plenum layer into said region; continuously supplying a flow of chemical materials for said first and second plenums, for each said region.
