摘要:
In a manufacturing method for a semiconductor memory device, wherein a capacitor having a double fin-shaped structure is provided, a storage electrode is formed by applying a thick planar material (31) which is capable of being wet-etched, between the double fins consisting of conductive layers (30,34). Accordingly, the problem of a photolithography process caused by poor step difference of a conventional fin structure can be solved. By removing the wet-etchable material (31) before pattern-etching the first conductive layer (30) the storage electrode surface is less likely to be damaged as compared to a RIE step. Further, the storage electrode may be formed by using a thin high temperature oxide film (41) whose etching rate is great. Thus, the cell's topography may be improved and damage to the storage electrode decreased.
摘要:
A dynamic random access memory device includes a storage capacitor (C) having a plurality of stacked conductive films (26a₁, 26a₂,..., 26a n ) which form a storage electrode (26a). A gap is formed between elevationally adjacent conductive films so as to surround the storage electrode. A gap (24₁) is formed between an insulating film (15) which covers a gate electrode (WL1) for insulation and a lowermost film (26a₁) of the storage electrode. Connection between the adjacent films is established so that an uppermost film (36₂) elevationally extends so as to make contact with a drain region (13). Also, connection can be established so that an upper film (46₂) is mounted directly on an lower film (46₁). An end portion of the film is thicker than the other portion thereof. The stacked film structure may be produced by alternatively forming a film made of a material different from the insulating film covering the gate electrode, and a conductive film.
