    摘要: A transistor including a recessed gate structure having improved doping characteristics and a method for forming such a transistor. The transistor includes a recess in a semiconductor substrate, where the recess is filled with a recessed gate structure including an impurity doped layer and a layer doped with a capture species. The capture species accumulates the impurity and diffuses the impurity to other layers of the recessed gate structure.
