发明名称 Semiconductor device having a dummy gate
摘要 A semiconductor device includes a plurality of MOS transistors, wherein each of the MOS transistors has a drain region, a pair of source regions sandwiching therebetween the drain region, and a pair of normal gates each overlying a space between the drain region and a corresponding one of the source regions. A plurality of dummy gates are provided each between adjacent two of the MOS transistors. The dummy gate electrodes are maintained at an equi-potential with the adjacent drain regions. MOS transistors include a row of pMOS transistors and nMOS transistors, wherein each of pMOS transistors and a corresponding nMOS transistor configure a CMOS gate, and a plurality of CMOS gates configure a ring oscillator.
