Abstract:
An overload regulating structure for trackball device includes a base, a top cover, a ball, a circuit board, a plurality of rotatable shafts and disks, and an overload regulator. The ball is three-point supported in the base between the rotatable shafts and the overload regulator. When the ball is subject to an overload, springs in the overload regulator are compressed, allowing the ball to sink into a locating recess in the base and be restricted from rotating freely and thereby protected against the overload. When the ball is released from the overload, the springs in the overload regulator elastically push the ball to the original three-point supported position again.

Disclosed is a semi-open method of growing an epitaxial HgCdTe layer on a CdTe substrate, including the steps of placing the CdTe substrate and a growth solution of Hg, Cd, and Te within a pressure and temperature controlled container, flowing an inert gas under pressure through the container to reduce the vaporization of Hg from the solution, establishing a cooling zone within the container to condense Hg vaporized from the solution, increasing the temperature of the solution for a time sufficient to react the Hg and Cd with the Te in the solution, reducing the temperature of the solution, establishing contact between the solution and the substrate, maintaining the solution at a temperature sufficient to melt the substrate for a time sufficient to eliminate a Hg vapor diffused layer, reducing the temperature of the solution to near the saturation temperature, and reducing the temperature of the solution at a rate sufficient to cause the solution to crystallize in an HgCdTe layer on the CdTe substrate.

Abstract:
The invention provides a method of manufacturing a thin film transistor capable of reducing the induced photo-electric current and thus improving the quality of the liquid crystal display, and reducing the number of required photo masks saving on the cost of fabrication. A stack structure is formed first, by successively depositing a gate electrode, a first insulation layer, a semiconductor layer, an ohmic contact layer, and a photoresist layer. Subsequently, a second insulation layer is deposited on the substrate, and the photoresist layer and the second insulation layer on the photoresist layer are removed in a lift-off process. Last, a source electrode, a drain electrode, a passivation layer, and a transparent electrode layer, are formed to complete the thin film transistor process.

Abstract:
A transflective liquid crystal display comprises a top plate comprising a transparent electrode; a bottom plate bonded to the bottom plate, the bottom plate comprising transflective electrodes of aluminum nitride; a liquid crystal layer interposed between the top plate and the bottom plate; and a light source behind the bottom plate. The transflective electrodes reflect incident ambient light and transmit light emitted by the light source. In the liquid crystal display according to the present invention, the transflective electrodes of aluminum nitride replace conventional transparent pixel electrodes such that an image is generated by the transflective liquid crystal display when either ambient light is incident on the surface of the top plate or when light is generated by the light source.
Abstract:
HgCdTe semiconductor material having an n-type epitaxial layer is grown on a substrate. A graded p-type epitaxial layer is grown on the n-type layer. The p-type layer is graded such that the large bandgap region is adjacent the heterojunction with the narrow bandgap region at the surface of this layer. The periphery of the p-type layer is then etched to expose the large bandgap material. A HgCdTe passivation layer may then be formed on the p-type layer. A resultant structure is then mesa etched. A metal, such as indium, is formed along the walls of the mesa structure. Indium is selected to form a good ohmic contact with the n-type layer and a Schottky barrier with the large bandgap exposed edge of the p-type layer. In this way, the PN junction is passivated at the large bandgap material. The remaining narrow bandgap material in the p-type will form a good ohmic contact to a metal contact formed on this layer.
