Abstract:
1. A method for fabricating a capacitor of a semiconductor device, the method comprising: forming a transistor including a gate electrode and a landing plug contact over a substrate; forming a first insulating film including a via-contact connected to the landing plug contact over the transistor; growing a silicon layer to top portion of the first insulating film from the landing plug contact through the via-contact; forming a second planarized insulating film over the grown silicon layer and the first insulating film; forming a porous anodic alumina structure including a hole over the silicon layer and the second insulating film; forming a metal layer in the bottom portion of the hole of the porous anodic alumina structure; growing a silicon nanowire structure with the porous anodic alumina structure and the metal layer; removing the porous anodic alumina structure and the metal layer; and forming a dielectric film and an upper electrode over the resulting structure including the silicon nanowire structure.
