Patent number: 8669553Abstract: A thin-film transistor includes a gate electrode, a gate dielectric disposed on the gate electrode, a channel layer, and a passivation layer. The channel layer has a first surface and an opposed second surface, where the first surface is disposed over at least a portion of the gate dielectric. The channel layer also has a first oxide composition including at least one predetermined cation. The passivation layer is disposed adjacent to at least a portion of the opposed second surface of the channel layer. The passivation layer has a second oxide composition including the at least one predetermined cation of the first oxide composition and at least one additional cation that increases a bandgap of the passivation layer relative to the channel layer.Type: GrantFiled: July 2, 2010Date of Patent: March 11, 2014Assignees: Hewlett-Packard Development Company, L.P., Oregon State UniversityInventors: Chris Knutson, Rick Presley, John F.

Patent number: 7888207Abstract: Enhancement mode, field effect transistors wherein at least a portion of the transistor structure may be substantially transparent. One variant of the transistor includes a channel layer comprising a substantially insulating, substantially transparent, material selected from ZnO or SnO2. A gate insulator layer comprising a substantially transparent material is located adjacent to the channel layer so as to define a channel layer/gate insulator layer interface. A second variant of the transistor includes a channel layer comprising a substantially transparent material selected from substantially insulating ZnO or SnO2, the substantially insulating ZnO or SnO2 being produced by annealing. Devices that include the transistors and methods for making the transistors are also disclosed.Type: GrantFiled: February 5, 2007Date of Patent: February 15, 2011Assignee: State of Oregon Acting by and through the Oregon State Board of Higher Eduacation on behalf of Oregon State UniversityInventors: John F.
