Flow-fill spacer structures for flat panel display device
View Patent ↗A preferred embodiment of the invention is directed to support structures such as spacers used to provide a uniform distance between two layers of a device. In accordance with a preferred embodiment, the spacers may be formed utilizing flow-fill deposition of a wet film in the form of a precursor such as silicon dioxide. Formation of spacers in this manner provides a homogenous amorphous support structure that may be used to provide necessary spacing between layers of a device such as a flat panel display.
1. A device, comprising:
a photoresist material, formed over a substrate, having at least one opening to expose at least one portion of the substrate,
the at least one opening being filled with a fluid precursor material to form a spacer material for providing a homogenous amorphous support structure between first and second devices of the device.
2. The device as recited in claim 1 , wherein said fluid precursor material is a sol-gel precursor material.
3. The device as recited in claim 2 , wherein said fluid precursor material is deposited by chemical vapor deposition.
4. The device as recited in claim 1 , wherein the first and second devices comprise a multi-layer device.
5. The device as recited in claim 4 , wherein the multi-layer device is a flat panel display.
6. The device as recited in claim 1 , wherein the spacer material provides a uniform distance between the first and second devices.
7. The device as recited in claim 1 , wherein the fluid precursor material extends beyond the at least one opening.
8. The device as recited in claim 1 , wherein the spacer material is formed in an I-shaped structure.
9. The device as recited in claim 1 , wherein the spacer material is formed in a T-shaped structure.
10. The device as recited in claim 2 , wherein the fluid precursor material is deposited by a flow fill deposition technique.
