ABSTRACT:
A method for fabricating a type of bit line is able to form a small-sized bit line. In this method a first dielectric layer, a first conductive layer, and a second conductive layer are formed on a substrate in sequence. The first dielectric layer is exposed, then a second conducting wire and a first conducting wire are formed, respectively. A portion of the second conducting wire is removed by a cleaning liquid, so that the feature size of the second conducting wire is less than the feature size of the first conducting wire. An oxide layer is formed on the second conducting wire and the first conducting wire by performing a thermal treatment. The feature size of the second conducting wire is approximately equal to the feature size of the first conducting wire.
