Organic Film Patterning

(above) A CNC milling machine used for rapid custom fabrication of shadow masks. It is also used to make custom PCB circuit boards for test equiptment.

(above) Organic Vapor Jet Printing(OVJP) can grow patterned organic semiconductor films without the use of shadow masks. In OVJP, organic vapor is carried through a nozzle by an carrier gas. The nozzle creates a jet that draws patterns on a moving substrate. OVJP can be used to grow OLED arrays for both display and lighting purposes.
