  • Patent number: 8552559
    Abstract: A new interconnection scheme is described, comprising both coarse and fine line interconnection schemes in an IC chip. The coarse metal interconnection, typically formed by selective electroplating technology, is located on top of the fine line interconnection scheme. It is especially useful for long distance lines, clock, power and ground buses, and other applications such as high Q inductors and bypass lines. The fine line interconnections are more appropriate to be used for local interconnections. The combined structure of coarse and fine line interconnections forms a new interconnection scheme that not only enhances IC speed, but also lowers power consumption.

  • Publication number: 20080197422
    Abstract: A planar combined structure of a bipolar junction transistor (BJT) and n-type/p-type metal semiconductor field-effect transistors (MESFETs) and a method for forming the structure. The n-type GaN MESFET is formed at the same time when an inversion region (an emitter region) of the GaN BJT is formed by an ion implantation or impurity diffusion method by using a particular mask design, while a p-type GaN region is at the same time is formed as the p-type GaN MESFET. Namely, the n-type channel of the n-type MESFET is formed by the ion implantation or impurity diffusion method when the BJT is formed with the same ion implantation or impurity diffusion method performed, while a region of the p-type GaN without being subject to the ion implantation or impurity diffusion method is formed as the p-type MESFET. As such, the BJT is formed currently with the n-type/p-type MESFETs on the same GaN crystal growth layer as a planar structure.

  • Publication number: 20070284619
    Abstract: In a low power consumption mode in which prior data is retained upon power shutdown, the return speed thereof is increased. While use of an existent data retaining flip-flop may be considered, this is not preferred since it increases area overhead such as enlargement of the size of a cell. A power line for data retention for power shutdown is formed with wirings finer than a usual main power line. Preferably, power lines for a data retention circuit are considered as signal lines and wired by automatic placing and mounting. For this purpose, terminals for the power line for data retention are previously designed by providing the terminals therefor for the cell in the same manner as in the existent signal lines. Additional layout for power lines is no longer necessary for the cell, which enables a decrease in the area and design by an existent placing and routing tool.
