  • Patent number: 6757978
    Abstract: Scissors for angularly cutting sheet stock is disclosed. The scissors comprises oblique slots in a lower handle, fasteners in the oblique slots, a rear elongate slot in a lower ridge of a board, and a pin slidably defined in the elongate slot. In a closed state, fasteners are slid to a lowest point in the oblique slot to be urged by the ridge so that the ridge is prevented from further rearward movement with energy stored in a resilient piece. In a cutting operation press the lower and the upper handles against each other for causing the board and the blade to close on the sheet stock. The ridge pivots in response to pivoting the lower handle. Pin slides along the elongate slot to move the ridge. A rear portion of the board moves upward. A pointed end of the blade closes on a forward end of the board.

  • Patent number: 6756631
    Abstract: A stacked-gate cell structure having a tapered floating-gate layer and a laterally graded source/drain diffusion profile is implemented to form NAND cell strings over a self-aligned STI structure having a high coupling ratio. The paired string select lines and the paired ground select lines being formed over one-side tapered floating-gate layers are simultaneously defined by a spacer formation technique and are therefore scalable. Each of common-source conductive bus lines is formed over a first flat bed between a pair of sidewall dielectric spacers being formed over sidewalls of the paired ground select lines. A plurality of planarized common-drain conductive islands are formed over common-drain diffusion regions between another pair of sidewall dielectric spacers being formed over sidewalls of the paired string select lines and are patterned simultaneously with a plurality of metal bit-lines by using a masking photoresist step.
