SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A semiconductor device and a method for manufacturing the same are provided to form semiconductor patterns having fine and uniform widths in the opening part of a mold having a fine width. CONSTITUTION: A lower line(105) is formed in a y-axis direction on a semiconductor substrate(100). An upper line(190) is formed in an x-axis direction vertical to the lower line. A selection element is arranged in the crossing region of the upper line and the lower line. A memory element(180) is arranged between the selection element and the upper line. The selection element includes a semiconductor pattern(160) having a first and a second sidewall.
