  • Publication number: 20260117322
    Abstract: A molecular marker for identifying Vitis vinifera and its interspecific hybrid grapes and an application thereof are provided. Through whole-genome resequencing data analysis, a significant InDel locus IH1 is identified, which is located at 7,224,357 base pairs (bp) on chromosome 13 of grapes. This locus shows genotypic differences between Vitis vinifera and its interspecific hybrids. Through the differences in the number and distribution of electrophoretic bands, Vitis vinifera and its interspecific hybrids may be distinguished. Based on the characteristics of this molecular marker, it may be used for screening of interspecific hybrid progeny lines in the early stage of breeding and elimination of selfed progeny. At the same time, it may also conduct screening of the genetic background of seedlings.

  • Patent number: 7535058
    Abstract: A lateral DMOS structure includes a light doped p-type region beneath and near the gate at the drain side. The electric field on the surface near the gate is reduced. Thus the electric field near the gate decreases, and the SOA (safe operating area) of the lateral DMOS device increases and long time reliability improves. Moreover, the lateral DMOS of the invention can be fabricated without increasing the manufacturing cost.

  • Patent number: 7446012
    Abstract: The present invention relates to a lateral PNP transistor and the method of manufacturing the same. The medium doping N-type base area and the light doping P? collector area were first introduced in the structure before the formation of P+ doping emitter area and the collector area. The emitter-base-collector doping profile in the lateral and the base width of LPNP were similar to NPN. The designer can optimize the doping profile and area size of each area according to the request of the current gain (Hfe), collector-base breakdown voltage (BVceo), and early voltage (VA) of LPNP transistor. These advantages may cause to reduce the area and enhance performance of the LPNP transistor.

  • Publication number: 20070173026
    Abstract: The present invention discloses a method for fabricating bipolar integrated circuits, wherein LOCOS technology is used to define the active regions needed by all elements so that the self-alignment of the associated layers can be realized, and implant resistor regions are also directly defined in the active regions by local oxide layers; after base regions have been driven in the wafer, the resistors are implanted into the wafer so that the cost of resistor photomasks can be saved; silicon nitride is adopted to be the material of the dielectric layers of the capacitors, and with the characteristic of a buffering oxide etchant that etches oxide faster than it etches silicon nitride, the conventional deposition sequence of the dielectric layer is changed so that the formation of the dielectric layer needs only a single photomask.

  • Publication number: 20060148188
    Abstract: A fabrication method is applied to the bipolar integrated circuit, which combines with various patterns of the masks using in the different processes to form a combination mask. By using the combination mask, a silicon dioxide layer is etched to produce the open windows required in the different processes. Thereafter, according to the requirements of different processes, the unused windows are covered with photoresists to avoid the alignment errors resulted from the pattering and etching of different masks. Because the method doesn't need to reserve tolerance for alignment errors, the degree of integration of the semiconductor processes is enhanced and the cost of production is reduced.
