Patent ID: 7611587

Claim:
A material source evaporator for use with an evacuable interior deposition chamber in which evaporated materials are deposited on substrates, said evaporator comprising: a container having an output port and having an associated heater that can heat an vaporizable material provided in said container to provide a vapor thereof at said output port; a manifold having an input port and a plurality of output apertures on a common side thereof, including three positioned without centers thereof along a common straight line, and having an associated heater that can heat said material vapor provided in said manifold through said input port thereof to remain sufficiently vaporous to pass out of said output apertures, said output apertures being in a selected pattern in said manifold to provide a spatial distribution of said material vapor that results in a deposition thereof in a layer on an adjacent said substrate with a fixed position so that said layer has a thickness sufficiently uniform to be within three percent of that average thickness achieved over said substrate, and with at least one of said output apertures having a normal to a smooth geometric surface, a surface that is considered to extend across an aperture opening provided by that said output aperture to connect boundaries about that said opening, said normal extending at an angle to said manifold wall where that said output aperture is located therein and also with said one of said output apertures being rotatable about an axis at an angle to said normal; and a transport duct extending between said container output port and said manifold input port so as to transport only vapors for deposition and from vaporizable materials in coffesponding containers thereof including said vapors of said vaporizable materials in said container.
