Patent ID: 7767521

Claim:
A method of forming a contact pad of a semiconductor device comprising: forming a first active region at an outer portion of a cell region where an active area defined by an isolation layer is formed, the first active region having the same shape as that of an inner active region disposed inwardly from the outer portion of the cell region; concurrently, forming a third active region by adding at least two second active regions disposed in parallel with and adjacent to at least one end of the first active region at the outer portion of the cell region by a predetermined distance, the second active region having a shape different from that of the inner active region; and forming a first bit line contact pad on the first active region and below a first bit line passing over the first active region, to be connected with the first bit line; concurrently, forming an insulating layer on the third active region and below a second bit line passing over the third active region.
