    摘要: A first polysilicon film which contains phosphorus as an impurity is formed on a semiconductor substrate. A second polysilicon film which is higher in phosphorus concentration than the first polysilicon film is formed on the first polysilicon film. The second polysilicon film is anisotropically etched to expose a surface of the first polysilicon film. Thermal oxidation is then performed. A surface of the first polysilicon film and a surface of the second polysilicon film are oxidized according to their respective oxidization rates depending on their respective phosphorus concentrations. Thus, a semiconductor device in which the size of the gate electrode can be readily controlled and damage to the semiconductor substrate or the like can be suppressed, is obtained.

    摘要: Provided are a semiconductor device in which a MOS transistor of SAC structure and a MOS transistor of salicide structure are provided together, and a method of manufacturing the same. Each gate electrode (3) of gate structures (GT11 to GT13) is covered with an upper nitride film (4) and sidewall nitride film (5). Therefore, when an interlayer insulating film (10) being oxide film is selectively removed for forming contact holes (CH1 and CH2), the upper nitride film (4) and sidewall nitride film (5) are not removed, thereby preventing the gate electrode (3) from being exposed. Particularly, in the gate structures (GT11 and GT12), even when the contact hole (CH1) is dislocated to either side, no short-circuit is developed between a conductor layer (CL1) and the gate electrode (3). Thus, the gate structures (GT11 and GT12) can be disposed without being restricted by the alignment margin of the contact hole (CH1), and the distance between the gates can be reduced for attaining high integration.

    摘要: There are provided a method of manufacturing a semiconductor device which achieves a reduction in implantation masks, and such a semiconductor device. By implanting boron into NMOS regions using a resist mask and another resist mask as the implantation masks, p-type impurity regions serving as the halo regions of access transistors and drive transistors are formed. By further implanting phosphorus or arsenic into a PMOS region using another resist mask as the implantation mask, n-type impurity regions serving as the halo regions of load transistors are formed.
