Abstract
To manufacture a semiconductor device by a method including the steps of: forming an oxide over a substrate, a first conductor over the oxide, and a second conductor over the first conductor; forming a first insulator to cover the oxide, the first conductor, and the second conductor; forming an opening in the first insulator to divide the second conductor into a third conductor and a fourth conductor; forming a second insulator and a third insulator to cover the oxide and the first insulator; processing the second insulator and the third insulator into a fourth insulator and a fifth insulator; processing the first conductor using the fourth insulator and the fifth insulator as a mask to divide the first conductor into a fifth conductor and a sixth conductor; and removing the fifth insulator.
