发明名称 MANUFACTURING METHOD OF CAPACITOR IN SEMICONDUCTOR DEVICE
摘要 Example embodiment is provided to a method for manufacturing a semiconductor device, including forming a hard mask layer on a buried bit line and forming a storage node contact hole by using the selectivity between an interlayer insulating layer and the hard mask layer, thereby forming a contact hole using a mask of a line pattern instead of a hole pattern. Accordingly, a mask for the contact hole can be easily fabricated and the contact area can be maximized, thereby reducing the contact resistance.
