发明名称 Method for manufacturing semiconductor device
摘要 Disclosed herein is a method for manufacturing a semiconductor device. According to the present invention, a bit line contact region and a storage node contact region are simultaneously formed, and then a storage node contact hole is formed after a form of bit line to reduce a height of a finally formed storage node contact plug, thereby increasing a storage node open area and reducing a short circuit between the bit lines.
