An approximate but analytical expression for the surface held distribution
of RESURF LDMOSFETs is presented in terms of the device parameters and the
applied drain voltage, which allows calculation of the breakdown voltage vi
a the surface field as a function of the epitaxial layer length. Analytical
results are in fair agreement with numerical simulations as well as experi
mental results reported. (C) 2000 Published by Elsevier Science Ltd.
