摘要:
A super-junction trench MOSFET with closed cell layout having shielded gate is disclosed, wherein closed gate trenches surrounding a deep trench in each unit cell and the shielded gate disposed in the deep trench. Trenched source-body contacts are at least formed between the closed gate trenches and the deep trench. The deep trench has square, rectangular, circle or hexagon shape.
