Patent number: 8826529Abstract: A device includes a substrate (308) and a metallic layer (336) formed over the substrate (308) with a deposition process for which the metallic layer (336) is characterizable as having a pre-determinable as-deposited defect density. As a result of a fabrication process, the defect density of the metallic layer (336) is reduced relative to the pre-determinable as-deposited defect density of the same layer (336) or another layer having like composition and which is formed under like deposition conditions. In a related method, a substrate (308) is provided and a removable layer (330) is formed over the substrate (308). A metallic layer (336) is formed over the removable layer (330) and is patterned and etched to define a structure over the removable layer (330). The removable layer (330) is removed, and the metallic layer (336) is heated for a time beyond that necessary for bonding of a hermetic sealing cap (340) thereover.Type: GrantFiled: December 21, 2010Date of Patent: September 9, 2014Assignee: General Electric CompanyInventors: Andrew Joseph Detor, Reed Corderman, Christopher Keimel, Marco Aimi

Publication number: 20070273263Abstract: The present invention relates to gated nanorod field emission devices, wherein such devices have relatively small emitter tip-to-gate distances, thereby providing a relatively high emitter tip density and low turn on voltage. Such methods employ a combination of traditional device processing techniques (lithography, etching, etc.) with electrochemical deposition of nanorods. These methods are relatively simple, cost-effective, and efficient; and they provide field emission devices that are suitable for use in x-ray imaging applications, lighting applications, flat panel field emission display (FED) applications, etc.Type: ApplicationFiled: August 8, 2007Publication date: November 29, 2007Applicant: GENERAL ELECTRIC COMPANYInventors: Heather Hudspeth, Reed Corderman, Renee Rohling, Lauraine Denault
