发明名称 Trench DMOS power transistor with field-shaping body profile and three-dimensional geometry
摘要 Power MOSFET apparatus, and method for its production, that suppresses voltage breakdown near the gate, using a polygon-shaped trench in which the gate is positioned, using a shaped deep body junction that partly lies below the trench bottom, and using special procedures for growth of gate oxide at various trench corners.
