Why Does Shrinking MOS Device Dimensions Increase Electric Field?

Click For Summary
SUMMARY

The discussion centers on the relationship between shrinking dimensions of MOSFET devices and the resulting increase in electric field strength. It highlights the charge sharing phenomenon observed in short-channel MOSFETs, which is crucial for understanding short-channel effects. The reference text "Solid State Electronic Devices" by Ben G. Streetman is recommended for a comprehensive treatment of these concepts. The interconnected nature of these issues suggests a complex interplay that warrants further exploration.

PREREQUISITES
  • MOSFET device structure and operation

Why does electric field in MOS device tend to increase as device dimension
shrink

describe the cross-section of a MOSFET with short channel showing the charge
sharing phenomenon

can anyone help me to find out these two problems?
I could not find them out from the book

thanks a lot!

ben g streetman

has a proper treatment of the short channel effects and what happens when the channels are reduced.

basically, both issues are interlinked and is a bit long winded for here...
