Abstract: PURPOSE: A method for making a semiconductor device is provided to reduce a junction area by placing an oxide layer to a lower part of a capacitor junction, increase a refresh time, protect a capacitor junction, and enhance an operation characteristic of a semiconductor device. CONSTITUTION: An oxide layer is formed to a lower part of a capacitor junction area, and thus a leakage current in the junction area is reduced. In the step for forming the oxide layer to a lower part of the capacitor junction area, a pad oxide layer, a buffer poly and a nitride layer being an etching stop layer are sequentially formed on a semiconductor substrate(11). A capacitor junction is partially opened by an element isolation masking. STI process is performed, and is not remove of a nitride layer, buffer poly and pad oxide layer of an active area. The smoothing insulating layer is deposited on a total strucrure, and is smoothened. A photoresist layer is deposited on the total structure, a photoresist pattern is formed to partially open a capacitor junction area by the light-exposing/etching processes. The photoresist pattern is used as an etching mask, a buffer nitride layer is used as a buffer layer on the active area, and the exposed smoothing insulating layer is etched. The photoresist layer and the buffer nitride layer are removed, and then a conductive layer used in a capacitor junction is formed on a total structure. The conductive layer is smoothened and etched. A gate(21) is formed to a predetermined part of the semiconductor substrate.

If the amount of evaporation gas is over a reference level, the ECU drives the pump to feed the evaporation gas in the fuel tank into the chamber until the pressure in the fuel tank falls under a reference level. The ECU decides the amount of the evaporation gas in the chamber corresponding to a pressure value or a temperature value. If the pressure value is over a reference level, the ECU operates the purge solenoid valve to feed the evaporation gas in the chamber to the suction line until the pressure in the chamber falls under the reference level. When the cap of the fuel tank is opened, the pressure in the tank becomes the same as the atmospheric pressure. Then, the ECU drives the pump to send the evaporation gas in the tank to the chamber. Thereby, the emission of the evaporation gas into the atmosphere is restrained. Further, recombustion efficiency of the evaporation gas is enhanced by the regulated discharge of the evaporation gas.
