Patent number: 9306185Abstract: There is provided a process for forming a contained second layer over a first layer, including the steps: forming the first layer having a first surface energy; treating the first layer with a priming layer; exposing the priming layer patternwise with radiation resulting in exposed areas and unexposed areas; developing the priming layer to effectively remove the priming layer from either the exposed areas or the unexposed areas resulting in a first layer having a pattern of priming layer, wherein the pattern of priming layer has a second surface energy that is higher than the first surface energy; and forming the second layer by liquid depositions on the pattern of priming layer on the first layer. There is also provided an organic electronic device made by the process.Type: GrantFiled: October 14, 2013Date of Patent: April 5, 2016Assignee: E I DU PONT DE NEMOURS AND COMPANYInventors: Adam Fennimore, Jonathan M Ziebarth, Nora Sabina Radu

Patent number: 8907353Abstract: There is provided a process for forming a layer of electroactive material having a substantially flat profile. The process includes the steps of providing a workpiece having at least one active area; depositing a liquid composition including the electroactive material onto the workpiece in the active area, to form a wet layer; treating the wet layer on the workpiece at a controlled temperature in the range of ?25 to 80° C. and under a vacuum in the range of 10?6 to 1,000 Torr, for a first period of 1-100 minutes, to form a partially dried layer; and heating the partially dried layer to a temperature above 100° C. for a second period of 1-50 minutes to form a dried layer.Type: GrantFiled: July 18, 2013Date of Patent: December 9, 2014Assignee: E I du Pont de Nemours and CompanyInventors: Reid John Chesterfield, Nugent Truong, Jeffrey A Merlo, Adam Fennimore, Jonathan M Ziebarth

Patent number: 6863833Abstract: The invention provides microfabricated silicon substrates and devices having extremely small apertures (termed “nanoapertures”) and methods for producing such nanoapertures. The devices have a nanoaperture (which may have a diameter ranging from about a few millimeters to as small as a few nm) across a substrate effective to connect two regions separated by the substrate. The devices are suitable for the formation of lipid bilayer membranes across the apertures, and for use in devices such as biosensors. Substrates and devices may include multiple nanoapertures, which may each support a lipid bilayer membrane, allowing fault tolerant devices such as fault-tolerant biosensors, and allowing devices able to sense more than one target molecule.Type: GrantFiled: June 21, 2002Date of Patent: March 8, 2005Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: David M. Bloom, Mark C. Peterman, Jonathan M. Ziebarth

Publication number: 20030032946Abstract: The invention provides microfabricated devices and methods for directing the growth of a cell process to form an artificial synapse. The devices are called artificial synapse chips. The artificial synapse comprises a nanofabricated aperture (about 50-100 nm in size) that connects the cell process to a chemical or electrical means of neuronal excitation. Such an aperture width mimics the length scales of a natural synapse and thus emphasizes the localized spatial relationship between a neuron and a stimulation source. The invention further provides devices and methods for regenerating a nerve fiber into an electrode. The invention thus provides a regeneration electrode that uses a novel neural interface for stimulation and that uses novel surface methods for directing neuronal growth making possible in vivo connection of the devices to neural circuitry in a retina and other anatomical locations.Type: ApplicationFiled: June 27, 2002Publication date: February 13, 2003Inventors: Harvey A.
