  • Patent number: 7977254
    Abstract: A method of forming a gate insulator in the manufacture of a semiconductor device comprises conducting a photo-assisted electrochemical process to form a gate-insulating layer on a gallium nitride layer of the semiconductor device, wherein the gate-insulating layer includes gallium oxynitride and gallium oxide, and performing a rapid thermal annealing process. The photo-assisted electrochemical process uses an electrolyte bath including buffered CH3COOH at a pH between about 5.5 and 7.5. The rapid thermal annealing process is conducted in O2 environment at a temperature between about 500° C. and 800° C.

  • Patent number: 7951691
    Abstract: In a method for producing a thin film chip including an integrated circuit, a semi-conductor wafer having a first surface is provided. At least one cavity is produced under a defined section of the first surface by means of porous silicon. A circuit structure is produced in the defined section. The defined wafer section is subsequently released from the semiconductor wafer by severing local web-like connections, which hold the wafer section above the cavity and on the remaining semiconductor wafer.

  • Patent number: 7479417
    Abstract: A method for manufacturing a pixel electrode contact structure of a thin-film transistors liquid crystal display is disclosed. First, a transparent substrate having a first insulating layer thereon is provided. Afterward, a first metal layer and a second metal layer are sequentially formed on the substrate and then be patterned by a halftone technology and an etching process, wherein the second metal layer is removed within the pixel electrode contact area. In the meantime, the drain lines of the thin-film transistor comprising the first metal layer and the second metal layer are formed. Next, a patterned passivation layer is formed on the substrate. Finally, a pixel electrode layer directly connecting the first metal layers within the pixel electrode contact structure is formed on the substrate. This invention provides the pixel electrode contact structure with low contact resistance and prevents the current leakage from the drain line to the storage capacitor.

  • Patent number: 7335538
    Abstract: A method for manufacturing liquid crystal display substrates comprises the steps of: (a) providing a substrate having a transparent electrode layer and a metal layer; (b) forming a patterned photoresist layer through half-tone or diffraction; (c) defining signal line area and thin film diode area, or pixel area and conductive electrode-lines by etching; and (d) forming an oxidized layer on partial surface of the metal layer. The disclosure here provides a patterning process of lithography and etching with one photolithography of one single mask in the manufacturing of liquid crystal display substrates. Furthermore, the method disclosed here can effectively increase the yield of manufacturing, and reduce the cost of manufacturing.
