  • Publication number: 20240088246
    Abstract: Various embodiments of the present application are directed towards a control gate layout to improve an etch process window for word lines. In some embodiments, an integrated chip comprises a memory array, an erase gate, a word line, and a control gate. The memory array comprises a plurality of cells in a plurality of rows and a plurality of columns. The erase gate and the word line are elongated in parallel along a row of the memory array. The control gate is elongated along the row and is between and borders the erase gate and the word line. Further, the control gate has a pad region protruding towards the erase gate and the word line. Because the pad region protrudes towards the erase gate and the word line, a width of the pad region is spread between word-line and erase-gate sides of the control gate.

  • Patent number: 8591067
    Abstract: A light source device having a good heat dissipation capability is disclosed, in which heat generated by a light emitting device is conducted to a base fabricated by a porous material through a heat conducting mask or a heat conducting pipe. Due to a large area contact between the heat conducting mask or the heat conducting pipe and the base, the heat can be evenly conducted to the base, so that the base can absorb the heat and dissipate the heat to external, so as to improve a heat dissipation efficiency. Moreover, in the light source device of the disclosure, heat exchange of the light emitting device can be directly carried on through air convection, so that the heat generated by the light emitting device can be taken away from the light source device through heat exchange of cool air.

  • Patent number: 6918780
    Abstract: A snap fastener for the electrical socket comprises a housing, a receptacle and snap fastener. When the knob of the snap fastener is being turned, the downward hump of the knob will drive the bulge of the brake plate to rotate and finally fall into the bottom recess of the brake plate and the fork of the brake plate will move downward to clamp the electrical blades of the plug in place. When the knob is turned in the reverse direction, the bulge of the snap will rise from the recess and push upward the fork of the brake plate, so the electrical blades of the plug get loose and are easy to leave the socket. Or a screw shank is used instead of the snap to move down or up the brake plate by turning the knob only.
