Filed: 2001-12-24
Abstract: PURPOSE: A method for manufacturing a semiconductor device is provided to be capable of preventing the generation of voids in an interlayer dielectric by improving the forming step of the interlayer dielectric. CONSTITUTION: The first interlayer dielectric(140a) is formed at the upper portion of a semiconductor substrate(100), wherein the semiconductor substrate has a plurality of bit lines(110). The upper portion of the first interlayer dielectric is removed by carrying out a wet etching process for removing the voids generated at the upper portion of the first interlayer dielectric. Then, an interlayer dielectric pattern is formed by depositing the second interlayer dielectric(140b) on the entire surface of the resultant structure. Preferably, the second interlayer dielectric is formed by using the same material used for forming the first interlayer dielectric.
