摘要： There is disclosed a method of manufacturing a CMOS transistor, by which ion implantation process is selectively performed to the gate formed region of a polysilicon film after a NMOS transistor region and a PMOS transistor region are defined in the process of manufacturing a CMOS transistor. Thus, it can obtain a reliable device by solving the problem occurring when polysilicon films doped with different impurities are simultaneously etched and the problem that a tungsten film is oxidized due to a selective oxidization process after forming a tungsten gate electrode.

摘要： A method for fabricating a semiconductor device is disclosed. In a process for fabricating a CMOS transistor of a high integrated semiconductor device and a cell of a DRAM, a process for forming a dual gate electrode having a layered structure of a tungsten layer and a polysilicon layer includes the steps of forming a gate electrode shape from an undoped polysilicon layer, forming an insulating film spacer at sidewalls of the polysilicon layer, forming an LDD region, removing a portion of the undoped polysilicon layer to leave a predetermined thickness and to form an opening in which the tungsten layer will be formed, and respectively implanting different impurity ions into the undoped polysilicon layer respectively formed in the PMOS region and the NMOS region before forming the tungsten layer. Thus, it is possible to prevent etching residue from occurring and also prevent the semiconductor substrate from being damaged. In addition, it is possible to prevent the tungsten layer from being oxidized due to a high temperature process such as an ion plantation process for forming the LDD region and the source/drain region, thereby improving operational characteristics of the device and process yield.

摘要： Disclosed is an internal voltage generator which generates a stable internal voltage using two power up sensing means. Clamp means outputs a first voltage. First and second power up sensing means sense the external applied to the semiconductor device and output first and second control signals, respectively. A first switch receives the first voltage and a switch controller receives the first and second control signals from the first and second power up sensing means and controls turn on/off of the first switch. A second switch is turned on/off according to the second control signal from the second power up sensing means and receives a second voltage. An amplifier selectively receives the first and second voltages from the first and second switches and outputs the second voltage.
