    摘要: Provided is a method of manufacturing a semiconductor device, in which the thickness of a gate insulating layer of a CMOS device can be controlled. The method can include selectively injecting fluorine (F) into a first region on a substrate and avoiding injecting the fluorine (F) into a second region on the substrate. A first gate insulating layer is formed of oxynitride layers on the first and second regions to have first and second thicknesses, respectively, where the first thickness is less than the second thickness. A second gate insulating layer is formed on the first gate insulating layer and a gate electrode pattern is formed on the second gate insulating layer.

The buried insulating layer may be planarized to form a first device isolation layer in the first trenches and a second device isolation layer in the second trenches.

    摘要: A mask pattern is formed on a semiconductor substrate in which a cell region, a PMOS region, and an NMOS region are defined. Trenches are formed in the cell region, the PMOS region, and the NMOS region. A sidewall oxide layer and a protection layer are formed in the trenches, and a portion of the protection layer in the PMOS region is removed. A first device isolation insulating layer is formed on the substrate, filling the trenches. Portions of the first device isolation insulating layer are removed to expose the mask pattern and the trenches of the cell region and the NMOS region and to leave a portion of the first device isolation insulating layer in the trench in the PMOS region. A liner is formed on the portion of the first device isolation region in the trench in the PMOS region and conforming to sidewalls of the trenches in the cell region and the NMOS region. A second device isolation insulating layer is formed on the substrate, filling the trenches in the cell region and the NMOS region. Portions of the second device isolation insulating layer are removed to expose the mask pattern and to leave portions of the second device isolation insulating layer in the trenches of the cell region and the NMOS region.
