Abstract
Abstract A patterning system with a photoresist overhang allows material to be deposited onto a substrate in various positions by varying the angle from which the material is deposited, and by rotating the substrate. The patterning system can be used to fabricate a stack of organic light emitting devices on a substrate using the same patterning system and without removing the substrate from vacuum.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
129 words
An organic light emitting device comprising: a. a substrate having at least first, second and third contact pads; b. a first organic layer deposited on said substrate and contacting said first contact pad; c. a first electrode deposited on said first organic layer and contacting said second contact pad; d. a second organic layer deposited on said first electrode, wherein said second organic layer does not completely cover said first electrode; e. a second electrode deposited on said second organic layer and contacting said third contact pad; wherein light emission from said first organic layer occurs when a voltage is applied between said first and second contact pads and light emission from said second organic layer occurs when a voltage is applied between said second and third contact pads.
Claim 2
Dependent Claim
129 words
An organic light emitting device comprising: a. a substrate having at least first, second and third contact pads; b. a first organic layer deposited on said substrate and contacting said first contact pad; c. a first electrode deposited on said first organic layer and contacting said second contact pad; d. a second organic layer deposited on said first electrode, wherein said second organic layer does not completely cover said first electrode; e. a second electrode deposited on said second organic layer and contacting said third contact pad; wherein light emission from said first organic layer occurs when a voltage is applied between said first and second contact pads and light emission from said second organic layer occurs when a voltage is applied between said second and third contact pads.
Claim 3
Dependent Claim
64 words
The organic light emitting device of claim 1 further comprising: a. said substrate having a fourth contact pad; b. a third organic layer deposited on second electrode; c. a third electrode deposited on said third organic layer and contacting said fourth contact pad; wherein light emission from said third organic layer occurs when a voltage is applied between said third and fourth contact pads.
Claim 4
Dependent Claim
20 words
The organic light emitting device of claim 2 wherein said third organic layer does not completely cover said second electrode.
Claim 5
Dependent Claim
20 words
The organic light emitting device of claim 2 wherein said third electrode does not completely cover said third organic layer.
Claim 6
Dependent Claim
19 words
The organic light emitting device of claim 1 wherein said first organic layer completely covers said first contact pad.
Claim 7
Dependent Claim
20 words
The organic light emitting device of claim 1 wherein said first electrode does not completely cover said first organic layer.
Claim 8
Dependent Claim
20 words
The organic light emitting device of claim 1 wherein said second electrode does not completely cover said second organic layer.
