发明名称 Semiconductor device structures with capacitor containers and contact apertures having increased aspect ratios
摘要 Semiconductor device structures and methods of making such structures that include one or more etched openings (e.g., capacitor containers and/or contact apertures) therein with increased height-to-width ratios are provided. The structures of the present invention are formed by successive layer deposition wherein conventional patterning techniques may be utilized in a stepwise fashion as the height of the structure is increased. Further provided is a self-aligning interconnection structure which may be used to substantially vertically align openings formed in successively deposited, vertically placed structural layers of a semiconductor device. The interconnection structure utilizes a cap-and-funnel model that self-aligns to the center plane of an opening in a first structural layer and also substantially prevents subsequently deposited material from entering the opening.
