The mobility and carrier density of Al are 12 cm2/Vs and 1.98×1023 cm−3, respectively. The mobility and carrier density of Cu are 43.2 cm2/Vs and 8.5×1022 cm−3, respectively. a) Calculate the resisitivity of Al and Cu b) Which one would you use as interconnects in advanced CMOS nodes?
true or false
55. Velocity saturation leads the MOSFET to reach operation in saturation at a smaller voltage Vps 56. The saturation current in short channel MOSFET's increases due to velocity saturation 57. The MOSFET transconductance is exponentially dependent on the drain current 58. In velocity saturation regime short channel MOSFET's transconductance are independent of the input voltage 59. Sub-threshold conduction in short channel MOSFET's relates to tunneling through the ultrathin oxide 60. Sub-threshold current is linearly dependent on the...
