Patent ID: 8168268

Claim:
A method of forming a thin film material comprising: providing a deposition chamber; said deposition chamber including a substrate, a pore cathode having one or more pores for supplying a gas to said deposition chamber, a first anode, a first delivery device, and a second delivery device; said deposition chamber having a first direction extending from said pore cathode to said first anode; said first delivery device including a first delivery point; said second delivery device including a second delivery point positioned between said first delivery point and said substrate; said second delivery point being spatially displaced from said first delivery point in said first direction, with said second delivery point being between said pore cathode and said first anode; supplying a gas to said deposition chamber through said pores of said pore cathode; providing a first material stream to said first delivery device, said first delivery device injecting said pore material stream into said deposition chamber; establishing an electric field between said pore cathode and said first anode, said electric field initiating a plasma, said plasma comprising species derived from said gas and said first material stream, said plasma having a first distribution of species adjacent to said first delivery point and a second distribution of species adjacent to said second delivery point, the average lifetime of species in said second distribution differing from the average lifetime of species in said first distribution; and providing a second material stream to said second delivery device, said second delivery device injecting said second material stream into said plasma to form a composite plasma, said composite plasma comprising species derived from said gas, said first material stream and said second material stream.
