  • Publication number: 20240124163
    Abstract: A magnetic multi-pole propulsion array system is applied to at least one external cathode and includes a plurality of magnetic multi-pole thrusters connected adjacent to each other. Each magnetic multi-pole thruster includes a propellant provider, a discharge chamber, an anode and a plurality of magnetic components. The propellant provider outputs propellant. The discharge chamber is connected with the propellant provider to accommodate the propellant. The anode is disposed inside the discharge chamber to generate an electric field. The plurality of magnetic components is respectively disposed on several sides of the discharge chamber. One of the several sides of the discharge chamber of the magnetic multi-pole thruster is applied for one side of a discharge chamber of another magnetic multi-pole thruster.

  • 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.

  • Publication number: 20230363155
    Abstract: Various embodiments of the present application are directed towards an integrated memory chip comprising a memory array with a strap-cell architecture that reduces the number of distinct strap-cell types and that reduces strap-line density. In some embodiments, the memory array is limited to three distinct types of strap cells: a source line/erase gate (SLEG) strap cell; a control gate/word line (CGWL) strap cell; and a word-line strap cell. The small number of distinct strap-cell types simplifies design of the memory array and further simplifies design of a corresponding interconnect structure. Further, in some embodiments, the three distinct strap-cell types electrically couple word lines, erase gates, and control gates to corresponding strap lines in different metallization layers of an interconnect structure. By spreading the strap lines amongst different metallization layers, strap-line density is reduced.

  • Patent number: 11798836
    Abstract: A semiconductor isolation structure includes a silicon-on-insulator wafer, a first deep trench isolation structure and a second deep trench isolation structure. The silicon-on-insulator wafer includes a semiconductor substrate, a buried insulation layer disposed on the semiconductor substrate, and a semiconductor layer disposed on the buried insulation layer. The semiconductor layer has a functional region. The first deep trench isolation structure penetrates the semiconductor layer and the buried insulation layer, and surrounds the functional region. The second deep trench isolation structure penetrates semiconductor layer and the buried insulation layer, and surrounds the first deep trench isolation structure.

  • Publication number: 20230290411
    Abstract: Various embodiments of the present application are directed towards an integrated memory chip with an enhanced device-region layout for reduced leakage current and an enlarged word-line etch process window (e.g., enhanced word-line etch resiliency). In some embodiments, the integrated memory chip comprises a substrate, a control gate, a word line, and an isolation structure. The substrate comprises a first source/drain region. The control gate and the word line are on the substrate. The word line is between and borders the first source/drain region and the control gate and is elongated along a length of the word line. The isolation structure extends into the substrate and has a first isolation-structure sidewall. The first isolation-structure sidewall extends laterally along the length of the word line and underlies the word line.
