    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).

    摘要: To ensure proper electrical insulation under thick-field isolation regions (23) grown in triple-well structures, the channel-stop impurity (30) is implanted using multiple doses at different energies, depending on the oxide thickness of the thick-field isolation regions (23). The split-implant procedure results in much wider process variation windows for the thick-field isolation regions (23). Process variations include oxide thickness of grown oxide, implant energy/dose and reduced thickness caused by wet de-glazing steps.
