Reza Stegamat has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20040265623
    Abstract: An embodiment of the present invention pertains to an electronic device that includes a substrate, a first electrode on the substrate, and substantially electrically isolated conducting polymer regions on the first electrode. The substantially electrically isolated conducting polymer regions are formed by selectively depositing a solution that includes water, polyethylenedioxythiophene (“PEDOT”), and polystyrenesulfonic acid (“PSS”), and a ratio of the PEDOT to the PSS is such that the solution has high conductivity.

  • Publication number: 20040241972
    Abstract: An embodiment of the present invention pertains to an electrode that includes a metal oxide layer, and a conductive layer on that metal oxide layer. The metal oxide layer is an alkali metal oxide or an alkaline earth metal oxide that is formed by: (1) decomposing a compound that includes (a) oxygen and (b) an alkali metal or an alkaline earth metal, or (2) thermally reacting at least two compounds where one of the at least two compounds includes the alkali metal or the alkaline earth metal, and another one of the at least two compounds includes oxygen. The metal oxide layer can also be formed by thermally reacting at least two compounds where one of those compounds includes (a) oxygen and (b) an alkali metal or an alkaline earth metal.

  • Publication number: 20040075382
    Abstract: An embodiment of the present invention pertains to an electrode that is substantially transparent and conductive and that is incorporated within an organic electronic device. This electrode includes a first layer and a second layer that is on the first layer. The electrode optionally includes a third layer on the second layer. The first layer, the second layer, and the third layer are exposed to a medium and reactions between various combinations of the first layer, the second layer, the third layer, and the medium produce the substantially transparent and conductive electrode.
