Latest Patents

Yuanyuan Tu's recent patents include two noteworthy inventions:

1. **Split Gate CSTBT with Current Clamping PMOS and Manufacturing Method Thereof**

This invention introduces a split gate carrier stored trench bipolar transistor (CSTBT) that incorporates a P-type buried layer and a split gate electrode equal to an emitter metal. This modification effectively mitigates the impact of an N-type carrier stored layer on the device's breakdown characteristics through charge compensation. Consequently, it improves the trade-off between the on-state voltage drop and turn-off loss, reduces saturation current, enhances the short-circuit safe operating area, decreases Miller capacitance, and boosts switching speed.

2. **Three-Dimensional Carrier Stored Trench IGBT and Manufacturing Method Thereof**

In this patent, Tu developed a three-dimensional carrier stored trench IGBT that also features a P-type buried layer and a split gate electrode. This design tackles issues similar to those addressed in his CSTBT patent, such as the on-state voltage drop and turn-off loss by optimizing charge compensation. The arrangement of the gate electrodes in the Z-axis direction allows for increased channel density control, leading to reduced saturation current and an expansive short-circuit safe operating area.
