    摘要: A semiconductor device having a contact barrier for insulating contacts with a large aspect ratio and having a fine pitch between adjacent conductive lines and a method of manufacturing the same are provided. The semiconductor device includes a buried contact formed in a region between two adjacent first conductive lines and two adjacent second conductive lines. Insulating lines define a width of the buried contact. To form the contact barrier, an interlayer dielectric layer formed on the second conductive lines is patterned to form a space and an insulating line having an etching ratio different from the interlayer dielectric layer is formed in the space. The interlayer dielectric layer is selectively wet etched relative to an insulating layer covering the second conductive line and the first insulating line to form buried contact hole. The buried contact hole is filled with conductive material to form a buried contact.
