Abstract: A toner feeding adjustment device for an image forming apparatus is provided to adjust toner feeding to maximally use a usable remaining toner due to an error of judgment that a toner barrel is empty in a time for replacing the toner barrel. A toner remaining quantity predicting unit(220) predicts a toner remaining quantity in a toner barrel. A control unit(210) has a mode converting unit(211) and a driving control unit(212). When the toner remaining quantity predicting unit(220) predicts that the toner remaining quantity does not exist, the mode converting unit(211) converts a current mode into a discharge mode for perfectly discharging a toner in the toner barrel. The driving control unit(212) controls the toner discharge of the toner barrel. A driving unit(270) drives a screw in the toner barrel under the control of the control unit(210), and discharges the toner.

Abstract: A method for fabricating a semiconductor device is provided to improve a phenomenon that a tunnel oxide layer becomes thinner, by forming a preliminary tunnel oxide layer, by partially etching an isolation layer and by transforming the preliminary tunnel oxide layer into an oxide layer by a re-oxidation process. An isolation layer pattern has first and second portions, exposing an active region(100b) of a substrate(100). The first portion protrudes from the surface of the substrate. The second portion is buried in the substrate, having a greater width than that of the first portion. A preliminary tunnel oxide layer and a floating gate pattern(122a) are formed on the active region. A part of the isolation layer pattern is eliminated to expose the sidewall of the floating gate pattern. The preliminary tunnel oxide layer is re-oxidized to be a tunnel oxide layer(120a) by thermal oxidation, radical oxidation or plasma oxidation.

Abstract: A method for forming a gate structure in a semiconductor device is provided to prevent resistance of a gate from being increased by oxidation of a metal gate electrode by selectively oxidizing a gate oxide layer and a metal gate electrode by a radial oxide method in an atmosphere with rich hydrogen gas during a reoxidation process for curing the gate oxide layer. A preliminary gate structure(121) in which a preliminary gate oxide layer and a metal layer are stacked is formed on a semiconductor substrate(100). The metal layer is made of tungsten, cobalt or titanium. Oxygen-including gas and hydrogen gas are supplied at a flowrate of 1:8 or higher to the resultant structure to control surface oxidation of the metal layer while the oxidation rate of the surface of the metal layer is adjusted to be higher than that the oxidation rate of the surface of the metal layer. The oxygen-including gas can be O2 or O3. During the process for forming the preliminary gate structure, a re-oxidation process for curing the damage of the preliminary gate oxide layer is performed.
