    • PURPOSE: A trench isolation type semiconductor device and a fabricating method thereof are provided to prevent a dent phenomenon by using a pull-back method. CONSTITUTION: A trench is formed by etching the silicon substrate(30) including an etch protection layer pattern formed on an active region. A thermal oxide layer is formed on a sidewall of the trench. A reduced pattern is formed by etching the etch protection layer pattern. A liner layer(39') for oxygen barrier is deposited on the thermal oxide layer of the silicon substrate(30). A CVD(Chemical Vapor Deposition) silicon oxide layer is deposited on the silicon substrate(30) including the liner layer in order to fill the trench. An isolation layer(41) is formed by removing the CVD silicon oxide layer. The reduced pattern is removed. A buffer insulating layer(51) is formed on the active region of the silicon substrate(30).

    • PURPOSE: A method of manufacturing a semiconductor device is provided to ensure necessary insulation length between a lower conducting layer and a self-adjusting contact in a self-contact forming process. CONSTITUTION: A mask pattern(20) is formed on a metal silicide layer to expose a portion of the first metal silicide layer(14). The first etching solution(40) is used to perform an isotropic etching to an exposed portion of the first metal silicide layer(14) to form the second metal silicide layer(15). The second metal silicide layer(15) has a shallow groove(44). The second etching solution is used to remove defects due to silicon components residing on the surface of the second metal silicide layer(15). Then, the third metal silicide layer(16) is formed with a smooth surface(16s). The third metal silicide layer and a polysilicon layers(12) is etched to form a gate structure.
