Abstract
An organic vapor jet printing system includes a pump for increasing the pressure of an organic flux.
Claims26
An organic vapor jet printing system, comprising:
- a heated chamber configured to produce an organic flux, the flux including a carrier gas and a vapor of an organic material;
- a source cell configured to introduce the vapor and the carrier gas into the heated chamber;
- a nozzle body configured to direct the flux to a substrate;
- a transport line disposed between the heated chamber and the nozzle body, the transport line configured to convey the flux from the heated chamber to the nozzle body;
- and
- a pump connected to the line, the pump configured to pump the flux from the chamber to the transport line and to the nozzle body.
3 more elements
A method of depositing an organic film onto a substrate, comprising:
- heating an organic material to form an organic vapor;
- transporting the organic vapor in a carrier gas from a source cell into a heated chamber;
- heating the heated chamber sufficiently to form a substantially uniform organic flux of the carrier gas and organic vapor by diffusive mixing of the gas and vapor within the heated chamber;
- transporting the organic flux to a nozzle body;
- directing the organic flux to a cooled substrate;
- increasing the pressure of the organic flux with a pump before the organic flux exits the nozzle body;
- and
- depositing the organic material onto a surface of the cooled substrate to form an organic film on the substrate.
