Abstract: A manufacturing method of a split gate trench device includes forming an epitaxial layer on a substrate, and forming a trench in the epitaxial layer, wherein the trench is divided into a first part and a second part above the first part. A shielding gate and a shielding oxide layer are then formed in the first part, wherein the shielding oxide layer is located between the shielding gate and the trench and exposes the second part. The second part is filled with an oxide, two grooves having a contour that is wide at the top and narrow at the bottom are then formed in the oxide, and a part of a sidewall of the trench is exposed. A gate oxide layer is formed on an exposed surface of the sidewall, and a first top gate and a second top gate are then formed in each of the two grooves.

Abstract: A split gate trench device, including a substrate, an epitaxial layer having a trench, and a split gate structure, is provided. The epitaxial layer is formed on the substrate, and the split gate structure is disposed in the trench. The split gate structure includes a shielding gate, two top gates, a shielding oxide layer, a gate oxide layer, and an inter-gate oxide layer. Each of the two top gates has a shape that is wide at the top and narrow at the bottom.

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: The present disclosure, in some embodiments, relates an integrated chip. The integrated chip includes a substrate. A through-substrate-via (TSV) extends through the substrate. A dielectric liner separates the TSV from the substrate. The dielectric liner is along one or more sidewalls of the substrate. The TSV includes a horizontally extending surface and a protrusion extending outward from the horizontally extending surface. The TSV has a maximum width along the horizontally extending surface.

Abstract: A single piece light guide is disclosed herein. The single piece light guide may include a light rod and a lens. The single piece light guide may be formed using injection molding. The light guide may have one or more regions between the light rod and the lens. A housing may be provided for the light guide. The housing may have an opening that physically supports the light rod. Therefore, the light rod may be secured into place, which may prevent misalignment during use. The one or more regions between the light rod and the lens may assist in assembling and holding the light guide in the housing.

Abstract: An improved structure of an LED light includes a light source module and a heat dissipation module. The light source module includes a plurality the compartments formed therein and each of the compartments receives therein a light reflector and a light emission element. The compartments are provided with a seat at an end thereof distant from the light emission elements. Each of the compartments is provided with a cover mounted thereon. The heat dissipation module has an outer wall forming a heat dissipation fin section. The heat dissipation module receives therein a drive module electrically connected to the light emission element. The heat dissipation module is coupled to the seat. With such an arrangement, the loss of light is minimized to achieve optimum utilization. The heat dissipation module is kept away from the light source module so that excellent effect of heat dissipation can be achieved.
