Abstract
A semiconductor structure includes a semiconductor substrate, a trench being provided in the semiconductor substrate, and a gate being formed in the trench; an ion implantation layer located in the semiconductor substrate outside the trench, a top surface of the ion implantation layer being higher than that of the gate, and a bottom surface of the ion implantation layer being lower than the top surface of the gate and higher than a bottom surface of the gate; a transition layer located between the gate and the ion implantation layer, a bottom surface of the transition layer being lower than the top surface of the gate and higher than the bottom surface of the gate, and a doping concentration of the transition layer being lower than that of the ion implantation layer.
