Publication number: 20210043877Abstract: A method of making an OLED device includes providing a first undercut lift-off structure over the device substrate having a first array of bottom electrodes. Next, one or more first organic EL medium layers including at least a first light-emitting layer are deposited over the first undercut lift-off structure and over the first array of bottom electrodes. The first undercut lift-off structure and overlying first organic EL medium layer(s) are removed by treatment with a first lift-off agent comprising a fluorinated solvent to form a first intermediate structure. The process is repeated using a second undercut lift-off structure to deposit one or more second organic EL medium layers over a second array of bottom electrodes. After removal of the second undercut lift-off structure, a common top electrode is provided in electrical contact with the first and second organic EL medium layers.Type: ApplicationFiled: October 28, 2020Publication date: February 11, 2021Applicant: ORTHOGONAL, INC.Inventors: John Andrew DEFRANCO, Terrence Robert O'TOOLE, Frank Xavier BYRNE, Diane Carol FREEMAN

Patent number: 9991114Abstract: A method of patterning a device includes forming a fluorinated photopolymer layer over a device substrate. The photopolymer layer has a lower portion proximate the device substrate and an upper portion distal the device substrate. The fluorinated photopolymer layer includes a radiation-absorbing dye and a fluorinated photopolymer having a solubility-altering reactive group. The photopolymer layer is exposed to patterned radiation to form exposed and unexposed areas in accordance with the patterned radiation and a developed structure is formed by removing unexposed areas using a developing agent that includes a first fluorinated solvent. The lower portion of the exposed area of the photopolymer layer has a dissolution rate in the developing agent that is at least 5 times higher than a dissolution rate for the upper portion.Type: GrantFiled: June 23, 2017Date of Patent: June 5, 2018Assignee: ORTHOGONAL, INC.Inventors: Douglas Robert Robello, Terrence Robert O'Toole, Frank Xavier Byrne, Diane Carol Freeman, Charles Warren Wright, Sandra Rubsam, Kenneth Nicholas Boblak, Meng Zhao

Patent number: 9335636Abstract: A photopolymer layer is formed on an organic device substrate and exposed to patterned radiation. The photopolymer layer includes a photopolymer comprising at least a first repeating unit having an acid-catalyzed, solubility-altering reactive group, wherein the total fluorine content of the photopolymer is less than 30% by weight. The pattern exposed photopolymer is contacted with a developing agent, such as a developing solution, to remove unexposed photopolymer, thereby forming a developed structure having a first pattern of exposed photopolymer covering the substrate and a complementary second pattern of uncovered substrate corresponding to the unexposed photopolymer. The developing agent comprises at least 50% by volume of a hydrofluoroether developing solvent.Type: GrantFiled: July 24, 2015Date of Patent: May 10, 2016Assignee: ORTHOGONAL, INC.Inventors: John Andrew DeFranco, Francis Houlihan, Charles Warren Wright, Diane Carol Freeman, Frank Xavier Byrne, Douglas Robert Robello, Sandra Rubsam, Terrence Robert O'Toole
