Abstract: A method of fabrication of a multi-gate semiconductor device that includes providing a fin having a plurality of a first type of epitaxial layers and a plurality of a second type of epitaxial layers. The plurality of the second type of epitaxial layers is oxidized in the source/drain region. A first portion of a first layer of the second type of epitaxial layers is removed in a channel region of the fin to form an opening between a first layer of the first type of epitaxial layer and a second layer of the first type of epitaxial layer. A portion of a gate structure is then formed in the opening.

Abstract: A circuit for in-memory multiply-and-accumulate functions includes a plurality of NAND blocks. A NAND block includes an array of NAND strings, including B columns and S rows, and L levels of memory cells. W word lines are coupled to (B*S) memory cells in respective levels in the L levels. A source line is coupled to the (B*S) NAND strings in the block. String select line drivers supply voltages to connect NAND strings on multiple string select lines to corresponding bit lines simultaneously. Word line drivers are coupled to apply word line voltages to a word line or word lines in a selected level. A plurality of bit line drivers apply input data to the B bit lines simultaneously. A current sensing circuit is coupled to the source line.

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.

Abstract: A fan of a heat sink comprising a hub, a plurality of ribs and a set of blades is provided. A distal end of the ribs is connected to circular sidewall of the hub and the set of blades are connected to the primal end of the ribs. The set of blades comprises an outer ring, multiple first blades, a guiding ring connected to the inner side of the first blades and multiple second blades positioned at the inner side of the first blades extending upwards from the top side of the guiding ring. The primal end of the ribs is connected to the guiding ring having an inclined slope extending from the hub towards the outer ring. The first and the second blades are adopted for increasing the air flow area, and thereby increase the air volume and air pressure and the inclined slope of the guiding ring is adopted to smoothly change the flow direction of the sucked air and thereby reduce the resistance to the air flow.

Abstract: A heat sink comprising an open frame including air inlets on a top side and a rotatable fan having a plurality of blades is provided. The heat sink is installed in the frame. The frame has pluralities of supporting elements and ribs positioned between two adjacent supporting elements. The supporting elements and ribs correspond to each other to form multiple side air inlets. The operation of the fan is capable of drawing a large volume of the air into the open frame via the top side and side air inlets. The flange of the blades is parallel to the inner curved side of the ribs when the blades pass by the ribs so that a large volume of air is guided into the frame to enhance the heat dissipation effect. This may also maintain an optimum static pressure and substantially reduce the noise level during the operation of the fan.

Abstract: A fan impeller of a heat-dissipating fan device is mounted in a receiving space of a fan housing, and includes coupling ribs that extend radially and outwardly from an outer surrounding surface of a hub cap and that are spaced apart angularly from each other, a smaller-diameter first connecting ring disposed coaxially around an intermediate portion of the hub cap and connected to the coupling ribs, a larger-diameter second connecting ring disposed coaxially around a lower portion of the hub cap, and fan blades that are spaced apart angularly from each other. Each fan blade has a first blade body connected to and disposed uprightly on the first connecting ring, and a second blade body connected to and extending radially from the first blade body and having a bottom end connected to the second connecting ring.
