Latest Patents

Wei Cui holds a patent for a "MOS device with resistive field plate for realizing conductance modulation field effect and preparation method thereof." This invention builds upon existing trench gate MOS devices by incorporating a semi-insulating resistive field plate. This plate is electrically connected to both the trench gate structure and the drain structure within the drift region. The trench gate structure effectively controls the on-off state of the MOS channel, while the resistive field plate adjusts the doping concentration of the drift region. This modulation leads to a lower on-resistance and improved distribution of the off-state high-voltage blocking electric field. The invention also utilizes modern 2.5-dimensional processing technology based on deep trench etching, which supports miniaturization and high-density design, aligning with the More than Moore development in integrated semiconductor devices.
