    摘要: A method of forming a semiconductor component having a conductive line (24) that crosses a trench (72). The method involves forming steps (104) in the sidewalls of the trench (72) in a semiconductor substrate (52). A dopant may be implanted at a first energy level into the semiconductor substrate (52) to form a first conductive region (92). The dopant may be implanted at a second energy level into the semiconductor substrate (52) to form a second conductive region (94). The first energy level may be greater than the second energy level. The first conductive region (92) and the second conductive region (94) may form the conductive line (24).
