  • Publication number: 20080283503
    Abstract: A method of processing nature pattern on expitaxial substrate, unlike the conventional method of processing regular pattern on expitaxial substrate (such as sapphire substrate) by lithography, wet etches a sapphire substrate directly to obtain a nature pattern, so as to simplify the fabrication process. Compared with the conventional way of processing pattern sapphire, the nature pattern sapphire substrate produced by the method can avoid voids between the interface of sapphire and GaN and apply this technology to a wired bond LED structure to increase the sidewall light extraction and improve the texture of the sapphire surface of a flip chip LED structure. In addition, this method also can be applied to a thin-GaN LED for achieving the surface texture after the sapphire is removed by laser.

  • Patent number: 7400368
    Abstract: Liquid crystal displays and fabrication methods thereof. The liquid crystal display comprises a first substrate with an active matrix of a plurality of pixels. A second substrate is provided opposing the first substrate. A liquid crystal layer is interposed between the first substrate and the second substrate. Each pixel comprises a polymer dispersed liquid crystal layer corresponding to a first liquid crystal region and a non-polymer dispersed liquid crystal layer corresponding to a second liquid crystal region.

  • Patent number: 7244567
    Abstract: This invention relates to methods of sequencing DNA. More specifically, this invention relates to methods of sequencing both the sense and antisense strands of DNA through the use of blocked and unblocked sequencing primers. In brief, these methods include the steps of annealing an unblocked primer to a first strand of nucleic acid; annealing a second blocked primer to a second strand of nucleic acid; elongating the nucleic acid along the first strand with a polymerase; terminating the first sequencing primer; deblocking the second primer; and elongating the nucleic acid along the second strand.

  • Publication number: 20060088857
    Abstract: The present invention relates to methods and apparatuses for conducting densely packed, independent chemical reactions in parallel in fluid-permeable arrays. Accordingly, this invention also focuses on the use of such arrays for applications such as DNA sequencing, most preferably pyrophosphate sequencing, and DNA amplification.

  • Patent number: 7035770
    Abstract: System and method for detecting suspicious process faults. A preferred embodiment comprises determining a strength relationship between wafer acceptance test (WAT) parameters and process steps. The strength relationships indicate the affect of a failed process step on the value of a WAT parameter. Thus, if a WAT parameter is not within the parameters set in the WAT, then the suspicious process steps that caused the failure are the process steps that had a strength relationship with the failed WAT parameter. Furthermore, in a preferred embodiment, negative inferences are determined and utilized to determine a degree of suspiciousness. The degree of suspiciousness is used to determine a total degree of suspiciousness.
