    摘要: A method of fabricating a uniformly wrinkled capacitor lower electrode without the need to perform a high-temperature heat treatment and a method of fabricating a capacitor including the uniformly wrinkled capacitor lower electrode are provided. A first conductive layer is formed. Then, a second conductive layer including about 20% to about 50% of impurities is formed on the first conductive layer. Next, at least some of the impurities are exhausted from the second conductive layer by heat treating the second conductive layer. A surface of the second conductive layer is wrinkled due to the exhaustion of the impurities from the second conductive layer. A dielectric layer and an upper capacitor electrode may then be formed.

    摘要: Provided are a semiconductor device and a method of fabricating the same. The semiconductor device includes an insulating layer that is formed on a supporting layer and has a contact hole. A first contact plug is formed on an inner wall and bottom of the contact hole. A second contact plug buries the contact hole and is formed on the first contact plug. A conductive layer is connected to the first contact plug and the second contact plug. The bottom thickness of the first contact plug formed on the bottom of the contact hole is thicker than the inner wall thickness of the first contact plug formed on the inner wall of the contact hole.
