Abstract

Methods of forming a semiconductor include forming an insulation layer over a semiconductor substrate in which a first region and a second region are defined. A storage node contact (SNC) that passes through the insulation layer is formed and is electrically connected to the first region. A conductive layer that passes through the insulation layer is deposited and is electrically connected to the second region on the insulation layer and the SNC. A bit line is formed by removing an upper portion of the conductive layer, an upper portion of the insulation layer and an upper portion of the SNC until the SNC and the conductive layer are electrically separated from each other, wherein the bit line is a remaining part of the conductive layer.
