Latest Patents

One of DeFranco's most recent patents focuses on the photolithographic patterning of organic electronic devices. This method involves providing a first undercut lift-off structure over a device substrate that contains a first array of bottom electrodes. Following this, multiple organic EL medium layers, including at least one light-emitting layer, are deposited over the structure. The undercut lift-off structure and the layers are then strategically removed using a specialized fluorinated solvent, resulting in a first intermediate structure. This process is thoughtfully repeated with a second undercut lift-off structure to apply additional organic EL medium layers over a second array of bottom electrodes. Finally, a top electrode is established in electrical contact, completing the OLED device.
