    摘要: In a method of manufacturing a semiconductor device such as a SONOS type semiconductor device, a trench is formed on a substrate. An isolation layer protruding from the substrate is formed to fill the trench. After a first layer is formed on the substrate, a preliminary second layer pattern is formed on the first layer. The preliminary second layer pattern has an upper face substantially lower than or substantially equal to an upper face of the isolation layer. A third layer is formed on the preliminary second layer and the isolation layer. A fourth layer is formed on the third layer. The fourth layer, the third layer, the preliminary second layer pattern and the first layer are partially etched to form a gate structure on the substrate. Source/drain regions are formed at portions of the substrate adjacent to the gate structure.

    摘要: An apparatus for etching a semiconductor substrate may include a bath, a reaction preventing layer, and a nozzle. The bath may receive a chemical solution. Grooves may be formed at the inner wall of the bath. The reaction preventing layer may be formed on the inner wall and in the grooves of the bath to reduce or prevent a chemical reaction between the chemical solution and the bath. The nozzle may supply the chemical solution to the bath. In a method of etching a semiconductor substrate, the semiconductor substrate having trench structures and an insulation layer pattern may be prepared. The semiconductor substrate may then be dipped into the bath having the reaction preventing layer in which the chemical solution is received. The semiconductor substrate may be reacted with the chemical solution by blocking the chemical reaction between the chemical solution and the bath to etch the insulation layer pattern and the trench structure at a uniform rate.
