Abstract
A manufacturing method of a semiconductor structure includes forming an active area in a substrate, in which the substrate has an array region and a peripheral region adjacent to the array region. A word line structure is formed in the array region of the substrate. A first protection layer is formed covering the active area and the word line structure. A hard mask stack is formed on the first protection layer. A bit line feature is formed in the first protection layer. After forming the bit line feature, a gate dielectric layer is formed on the active area in the peripheral region of the substrate. A gate electrode layer is formed on the gate dielectric layer.
