Organic Vapor Jet Printing
Organic vapor jet printing (OVJP) is a deposition technique in which a highly collimated jet composed of a mixture of a heated inert carrier gas and an organic vapor are deposited onto a substrate, resulting in high materials utilization efficiency and rapid, direct patterning of active layers in a range of organic optoelectronic devices. We are implementing new designs like OVJP with guard flow to improve the quality and rate of patterning in atmosphere. This technique can be used to address fabrication of cost effective, high performance organic semiconductors.
