Abstract:
A method for fabricating a semiconductor memory device, comprising the steps of:forming a first insulating layer on a substrate; etching the first insulating layer to form a contact hole, thereby exposing a portion of the substrate; forming a conductive film for a storage electrode over the first insulating layer including the contact hole; forming a photosensitive film in a portion of the contact hole over the conductive film; forming a second insulating layer to be completely filled in the contact hole over the photosensitive film; etching the second insulating layer and the conductive film to expose the first insulating layer, thereby forming the storage electrode; and removing the first and second insulating layers and the photosensitive film; wherein the steps for forming the photosensitive film includes the steps of: coating the photosensitive film over the conductive film to be filled in the contact hole; selectively radiating light to the photosensitive film; developing the photosensitive film to remain in the portion of the contact hole; and hardening the photosensitive film.
