Abstract:
A process reactor having a first and a second region and multiple plasma sources for fabricating portions of semiconductor devices comprising:a substrate holding chamber having an interior containing said first and second regions; a gas distribution plate having a top surface, a bottom surface, and a plurality of apertures therebetween, said gas distribution plate separating said first region from said second region and connecting said first and second regions through said plurality of apertures; a first gas inlet for supplying a first controlled gas flow at a first pressure level into said first region for maintaining a first temperature level within said substrate holding chamber during a plasma process; and a second gas inlet to said second region supplying a second gas flow split from said first gas inlet for variably adjusting said first pressure level and said first temperature level during said plasma process.
