Patent number: 7242383Abstract: An active matrix color crystal display has an active matrix circuit, a counterelectrode panel and an interposed layer of liquid crystal. The active matrix display is located in a portable microdisplay system that has a display computer that generates images to be displayed on the liquid crystal display and connected to the active matrix liquid crystal display. A data link transmits data at a rate of speed of greater than 200 Mbytes per second in series for at least a portion between the display computer and the active matrix liquid crystal display. In a preferred embodiment, the display system has a randomizing device that alternates the amplifier through which an analog video signal passes.Type: GrantFiled: May 10, 1999Date of Patent: July 10, 2007Assignee: Kopin CorporationInventors: Matthew Zavracky, Jeffrey Jacobsen, Frederick P.

Patent number: 7122841Abstract: A semiconductor device includes a substrate having a first major surface; a semiconductor device structure over the first surface of the substrate, the device structure comprising an n-type semiconductor layer, and a p-type semiconductor layer over the n-type semiconductor layer; a p-side electrode having a first and a second surface, wherein the first surface is in electrical contact with the p-type semiconductor layer; and a p-side bonding pad over the p-side electrode. Preferably, the semiconductor device further comprises an n-side bonding pad over an n-type semiconductor layer. The p-side and n-side bonding pads each independently includes a gold layer as its top layer and a single or multiple layers of a diffusion barrier under the top gold layer. Optionally, one or more metal layers are further included under the diffusion barrier. Typically, the p-side bonding pad is formed on the p-side electrode.Type: GrantFiled: June 3, 2004Date of Patent: October 17, 2006Assignee: Kopin CorporationInventors: Tchang-Hun Oh, Hong K.

Patent number: 7002180Abstract: A bonding pad for an electrode is in contact with p-type gallium nitride-based semiconductor material that includes aluminum. The bonding pad may also includes one or more metals selected from the group consisting of palladium, platinum, nickel and gold. The bonding pad can be used to attach a bonding wire to the p-electrode in a semiconductor device, such as a light-emitting diode or a laser diode without causing degradation of the light-transmission and ohmic properties of the electrode. The bonding pad may be formed of substantially the same material as an electrode in making an ohmic contact with n-type gallium nitride-based semiconductor material (n-electrode). This allows the bonding pad and the n-electrode to be formed simultaneously when manufacturing a gallium nitride-based light-emitting device which substantially reduces the cost to manufacture the device.Type: GrantFiled: June 28, 2002Date of Patent: February 21, 2006Assignee: Kopin CorporationInventors: Steve Tchang-Hun Oh, Hong K.
