What is Fowler-Nordheim Tunneling?

Answer / nikki
This is a phenomena associated with the gate thickness of a
transistor. When the thickness of oxide is very small there
exists a possibilty that electrons pass directly between
source and gate. This is a seond order effect and limits
the scaling down of transistor size.

FN Tunneling is only a second order effect, unless you are
desiging Flash memory. In which case, the FN tunneling is
the first order mechanism for programming and erasing the
memory cell.

Cross section of an NMOS transistor?
Are you familiar with VHDL and/or Verilog?
Give the expression for calculating Delay in CMOS circuit?
Cross section of a PMOS transistor?
what is the difference between the TTL chips and CMOS chips?
Let A & B be two inputs of the NAND gate. Say signal A arrives at the NAND gate later than signal B. To optimize delay, of the two series NMOS inputs A & B, which one would you place near the output?
Which gate is normally preferred while implementing circuits using CMOS logic, NAND or NOR? Why?
How do you detect a sequence of "1101" arriving serially from a signal line?
Implement a function with both ratioes and domino logic and merits and demerits of each logic?
For a NMOS transistor acting as a pass transistor, say the gate is connected to VDD, give the output for a square pulse input going from 0 to VDD
What types of CMOS memories have you designed? What were their size? Speed?
What are the two types of noise of MOSFET, how to eliminate them?(Thermal and Flicker).
