Abstract
A method of manufacturing semiconductor devices, including the steps of forming an insulating layer on a semiconductor substrate in which predetermined structures are formed, and etching the insulating layer to expose a predetermined region of the semiconductor substrate, thereby forming a contact hole, forming an insulating layer on the sides of the contact hole, and forming a conductive layer within the contact hole, forming a contact plug. It is possible to prevent a short problem by sufficiently securing a distance between a drain contact plug and a virtual power line.
