A method of fabricating a capacitor over bit line (COB) is provided. First, a substrate is provided and a plurality of word lines is formed on the substrate. Next, a plurality of landing plug contacts (LPCs) are formed between the word lines and a plurality of first contacts is then formed on the LPCs. Thereafter, a plurality of second contacts is formed on a first portions of the first contacts and a plurality of bit lines connecting a second portions of the first contacts is formed, simultaneously. An inter-layer dielectric (ILD) layer is formed on the substrate to cover the second contacts and the bit lines. Subsequently, a plurality of capacitors is formed in the ILD layer. Thus, the fabrication of the capacitor is simplified.
