摘要:
A semiconductor fabrication apparatus and a method of fabricating a semiconductor device using the same performs semiconductor etching and deposition processes at an edge of a semiconductor substrate after disposing the semiconductor substrate at a predetermined place in the semiconductor fabrication apparatus. The semiconductor fabrication apparatus has lower, middle and upper electrodes sequentially stacked. The semiconductor substrate is disposed on the middle electrode. Semiconductor etching and deposition processes are performed on the semiconductor substrate in the semiconductor fabrication apparatus. The semiconductor fabrication apparatus forms electrical fields along an edge of the middle electrode during performance of the semiconductor etching and deposition processes.
摘要:
In a method of manufacturing a semiconductor device including a capacitor, a first mold layer is formed on a semiconductor substrate. The first mold layer is partially etched to form a first mold layer pattern including an opening for a capacitor. A first lower electrode layer is formed on the first mold layer pattern. A second lower electrode layer including a plurality of first pores is formed on the first lower electrode layer and in the opening. Upper portions of the first lower electrode layer and the second lower electrode layer are removed to form a first lower electrode and a second lower electrode in the opening. A dielectric layer and an upper electrode are successively formed on the first lower electrode and the second lower electrode. Therefore, a capacitor having an enhanced capacitance may be obtained.

A capacitor for a semiconductor device includes a lower electrode, a dielectric layer formed on a lower electrode, and an upper electrode formed on the dielectric layer. The lower electrode includes a first layer having a cylindrical shape and a mesh second layer formed on inner sidewalls and the bottom surface of the first layer. Beneficially, the first layer is connected to a conductive region of a semiconductor substrate by a contact plug. The lower electrode can be formed by injecting a catalyst into an opening in which the cylindrical first layer is to be formed before forming the cylindrical first layer.
