The DUV-resist layer and the I-line resist layer are developed to form a T-shaped groove exposing a part of the interlayer dielectric by removing a portion in which an exposure is performed. The substrate of the resultant structure is hardened to control etch selectivity of the DUV-resist layer and the I-line resist layer with the insulating layer. The DUV-resist layer exposed by the I-line resist layer is etched by using the DUV-resist layer and the I-line resist layer as a mask while the interlayer dielectric is etched until a part of the substrate is exposed to form a contact hole of an interconnection type. The DUV-resist layer and the I-line resist layer are removed. An interconnecting metal layer is formed on the interlayer dielectric to fill the contact hole. The metal layer is entirely etched until the interlayer dielectric is exposed to form a metal interconnection.
