Patent ID: 7951696

Claim:
A method for fabricating a semiconductor device, the method comprising the steps of: depositing a first liquid dopant comprising first conductivity-determining type elements overlying a first region of a semiconductor material; depositing a second liquid dopant comprising second conductivity-determining type elements overlying a second region of the semiconductor material, wherein the first conductivity-determining type elements and the second conductivity-determining type elements are of opposite conductivity; depositing a barrier material overlying the first liquid dopant, the second liquid dopant or a combination thereof, the barrier material comprising material selected from the group consisting of silicon oxides, silicon nitrides, silicon carbides, siloxanes, silsesquioxanes, silicates, including organosilicates, titanium oxide, alumina, and barium titanate; and simultaneously diffusing at least a portion of the first conductivity-determining type elements into the first region and at least a portion of the second conductivity-determining type elements into the second region.
