Abstract

A method for fabricating a semiconductor memory apparatus is provided to minimize failure of the semiconductor memory apparatus and to secure a processing margin. The method also provides for minimizing the deterioration of an operating speed and the operational stability, and minimizing the increase of resistance occurring as a result of a reduced processing margin when forming a gate pattern in a peripheral region of the semiconductor memory apparatus. The method includes forming a connection pad in a peripheral region while forming a buried word line in a cell region, and forming a gate pattern in the peripheral region while forming a bit line in the cell region.
