    摘要: A method for fabricating a MIM capacitor of a MDL logic or analog circuit of a semiconductor device. A conductivity layer is formed on a semiconductor substrate having a first inter-level insulating layer. A capping metal layer having an etching rate higher than an oxide layer is formed on the conductivity layer. A lower electrode comprising a “conductivity layer/capping metal layer” deposition is formed by selectively etching the capping metal layer and the conductivity layer in order to expose a predetermined part of the surface of the first inter-level insulating layer. A second inter-level insulating layer is formed on the first inter-level insulating layer covering the lower electrode. A via hole is formed by selectively etching both the second inter-level insulating layer and the lower electrode thereby to expose a portion of the lower electrode so that a tapered capping metal layer remains along the lower edges of the via hole. A dielectric layer, devoid of step coverage defects and concentrated electric fields, is inserted in the via hole between the lower and upper electrodes thereby preventing current leakage and short circuits at portions of the dielectric layer. This has the beneficial effect of substantially improving product yield and reliability.

    摘要: A method for forming an integrated circuit device includes the steps of forming a first capacitor electrode on a substrate and forming a first wiring electrode on the substrate. An insulating layer is formed on the first capacitor electrode and on the first wiring electrode opposite the substrate. A second capacitor electrode is formed on a portion of the insulating layer opposite the first capacitor electrode. A contact hole is formed in the insulating layer exposing a portion of the first wiring electrode. A second wiring electrode is then formed on the exposed portion of the wiring electrode, after forming the second capacitor electrode. Related structures are also discussed.

    摘要: In a semiconductor device and a method of fabricating the same, a fuse and a capacitor are formed at a same level on a semiconductor substrate having a fuse area and a capacitor area. The fuse is placed on the fuse area, and a lower plate is placed on the capacitor area. The lower plate is located on a same plane as the fuse. Further, an upper plate is located above the lower plate, and a capping layer is interposed between the lower plate and the upper plate. Therefore, the fuse and the capacitor can be formed at the same time, thereby minimizing photolithography and etch process steps.
