  • Patent number: 9146071
    Abstract: A quick-release device for a crossbow stock assembly includes a main body having a fixing member which is threadedly connected to the extension of the stock. An axial groove is defined in the outside of the threaded section of the extension. A locking member is pivotably connected to the fixing member and positioned between a locked position and a release position. The locking member has an engaging end and a press end. The engaging end is engaged with the axial groove when the locking member is located at the locked position, and the engaging end is separated from the axial groove when the locking member is located at the release position. A collar is threadedly connected to the threaded section to keep the locking member at the locked position. The stock is quickly installed to or removed from the main body of the crossbow.

  • Patent number: 9136393
    Abstract: A method includes forming a selection gate and a control gate for a flash memory cell in a memory device region. The selection gate and the control gate are over a semiconductor substrate. A protection layer is formed to cover the selection gate and the control gate. Stacked layers are formed in a logic device region, wherein the stacked layers extend to overlap the selection gate and the control gate. The stacked layers are patterned to form a gate stack for a logic device in the logic device region. After the patterning, an etching step is performed to etch a residue of the stacked layers in a boundary region of the memory device region. After the etching step, the protection layer is removed from the memory device region. Source and drain regions are formed for each of the flash memory cell and the logic device.

  • Patent number: 9134624
    Abstract: The present disclosure provides a lithography machine and a scanning and exposing method thereof. According to the scanning and exposing method, the scanning and exposing process for a whole wafer includes two alternately circulated motions: a scanning and exposing motion and a stepping motion; and the scanning and exposing motion is a sinusoidal motion rather than a rapid-acceleration uniform-speed rapid-deceleration scanning and exposing motion in the conventional techniques. During the scanning of a single exposure shot, it may begin to scan the exposure shot once a wafer stage and a reticle stage begin to accelerate from zero speed. And the scanning and exposing may not end until the speeds of the wafer stage and the reticle decrease to zero. Therefore, the effective time of the scanning and exposing in the scanning and exposing motion is greatly increased and the production efficiency of the wafer is improved.

  • Publication number: 20150255718
    Abstract: The present disclosure relates to a resistive random access memory (RRAM) device architecture, that includes a thin single layer of a conductive etch-stop layer between a lower metal interconnect and a bottom electrode of an RRAM cell. The conductive etch-stop layer provides simplicity in structure and the etch-selectivity of this layer provides protection to the underlying layers. The conductive etch stop layer can be etched using a dry or wet etch to land on the lower metal interconnect. In instances where the lower metal interconnect is copper, etching the conductive etch stop layer to expose the copper does not produce as much non-volatile copper etching by-products as in traditional methods. Compared to traditional methods, some embodiments of the disclosed techniques reduce the number of mask step and also reduce chemical mechanical polishing during the formation of the bottom electrode.
