Abstract
A layout of a semiconductor device is disclosed, which forms one transistor in one active region to reduce the number of occurrences of a bridge encountered between neighboring layers, thereby improving characteristics of the semiconductor device. Specifically, the landing plug connected to the bit line contact is reduced in size, so that a process margin of word lines is increased to increase a channel length, thereby reducing the number of occurrences of a bridge encountered between the landing plug and the word line.
