    Abstract: The invention provides a method for reducing mismatch of semiconductor device patterns, which comprises the following steps: defining an initial lithography area which partially overlaps a target gate structure, a first gate structure and a second gate structure; if a length and a width of the target gate structure are smaller than a preset channel length and a preset channel width respectively, adjusting and reducing the area of the initial lithography area to define a second lithography area. The second lithography area partially overlaps with the target gate structure but does not overlap with the first gate structure and the second gate structure, and the second lithography region is defined as the active area.

  • Patent number: 8410750
    Abstract: A method for solar power energy management with intelligent selection of operating modes classifies the power energy of a solar cell and an reserved power of a rechargeable battery into multiple power level ranges, and determine to supply power to a load in accordance with various combinations of the power level ranges of the solar cell and the rechargeable battery to avoid energy waste. When the solar cell is in a “sufficient” power level range, the power energy of the solar cell is simultaneously supplied to the load and stored in the rechargeable battery. When the solar cell is in an “insufficient” power level range, all the power energy of the solar cell is selectively supplied to the load or charged to the rechargeable battery. When being in a “poor” power level range, the power energy of the solar cell can still be charged to the rechargeable battery.

    Abstract: A classified solar charging method defines four magnitude classes of charging current in accordance with a combination selected from four magnitude classes of power production of a solar cell and four magnitude classes of capacity of each rechargeable battery of a rechargeable battery pack. In addition to the optimal charging current, the method simultaneously takes an operating temperature of the rechargeable battery into account upon using the solar cell to store energy in the rechargeable battery. Accordingly, the present invention can selectively charge overall, partial or single rechargeable battery based on the power production of the solar cell and the capacity of the rechargeable battery to enhance a charging efficiency and reduce a charging time.
