Abstract: PURPOSE: A method for manufacturing a semiconductor device is provided to form a transistor capable of operating at a low voltage, by increasing the channel length formed under a gate electrode to decrease the threshold voltage. CONSTITUTION: An insulating layer pattern exposing a portion for an isolating region and a gate electrode is formed on a semiconductor substrate(11). The substrate is etched to form a trench. A burying insulation material is buried in the trench and etched by using a gate electrode mask reserved for the gate electrode as an etching mask. A gate insulating layer and a conductive layer for the gate electrode are formed on the entire surface. The conductive layer for the gate electrode, the gate insulating layer and a predetermined thickness of the insulating layer pattern are eliminated to form the gate electrode by a chemical mechanical polishing(CMP) process. A step is formed between the substrate and the gate electrode. A buffer layer is formed on the entire surface. A lightly-doped-drain(LDD) region(31) is formed, and an insulating layer spacer is formed in the stepped portion. A source/drain diffusion region is formed at both sides of the insulating layer spacer. An interlayer dielectric having a metal interconnection contact hole exposing the source/drain diffusion region and the gate electrode is formed. A diffusion blocking layer and a metal layer are formed. A metal interconnection contact(41) connected to the gate electrode and the source/drain diffusion region through the metal interconnection contact hole is formed by a CMP process.
