    Abstract: A manufacturing method of a trench power MOSFET is provided. In the manufacturing method, the trench gate structure of the trench power MOSFET is formed in the epitaxial layer and includes an upper doped region, a lower doped region and a middle region interposed therebetween. The upper doped region has a conductive type reverse to that of the lower doped region, and the middle region is an intrinsic or lightly-doped region to form a PIN, P+/N? or N+/P? junction. As such, when the trench power MOSFET is in operation, a junction capacitance formed at the PIN, P+/N? or N+/P? junction is in series with the parasitic capacitance. Accordingly, the gate-to-drain effective capacitance may be reduced.
