A method for fabricating a capacitor of a semiconductor device is disclosed, in which loss of and damage to a lower electrode is minimized to improve process yield. The compound is useful as a pharmaceutical for a central nerves system disease, a cardiovascular disease or a metabolic disease. The personal computer can communicate with a web server which receives the user’s request for content to be distributed to the handheld device. The apparatus also includes a plurality of adaptor plugs. The memory transistor is fommed together with the switch transistors in self-aligned diffusion.
