In a CMOS semiconductor device using a silicon germanium gate and a method of fabricating the same, a gate insulating layer, a conductive electrode layer that is a seed layer, a silicon germanium electrode layer, and an amorphous conductive electrode layer are sequentially formed on a ...
A technique for extracting a gate level logic model from transistor networks has been described. The resultant logic model can be technology dependent or technology independent, depending on control parameters and environment of the program. It handles all CMOS logic families including static, precharge...
For the 28 nm CMOS process, the n-type metal–oxide–semiconductor (NMOS) transistor transition frequency (ft) could reach 270 GHz, with the gate (VG) and drain (VD) biased at 0.7–0.8 V. Similarly, the bandwidth of a very short length of the modulator (in the depletion ...

Before CMOS, there was NMOS (also PMOS, but I have no direct experience with that). An NMOS gate consisted of a network of N-transistors between the output and Vss, and a resistor (actually a transistor with an implant) between the output and Vdd. If you are used to CMOS, that might...
Step 10 – Deposition of Polysilicon:The misalignment of the gate of aCMOS transistorwould lead to the unwanted capacitance which could harm circuit. So to prevent this “Self-aligned gate process” is preferred where gate regions are formed before the formation of source and drain using ion imp...
MOSFETs operate based on the field-effect transistor principle, wherein the channel current is modulated by an electric field produced by the voltage applied to the gate terminal. The gate voltage determines the extent of the electric field, either enhancing or depleting the concentration of charge...
dual-gate transistor based on a solution-processed organic heterojunction layer, we find that the presence of bothn- andp-type channels enables both photogenerated electrons and holes to efficiently separate and transport in the same semiconducting layer. This operation enables effective control of trap...
Ideally, it is desirable that the gate capacitance of the CMOS device be high since high gate capacitance typically equates to more charge being accumulated in the inversion layer. As more charge is accumulated in the channel, the source/drain current becomes higher when the transistor is biased...
