Dear BSIM Users, Thank you for your support of the BSIM models. We are releasing BSIM4.6.3 today (Sep., 19, 2008). The only change in BSIM4.6.3 compared with BSIM4.6.2 is the addition of a missing term (3.9/epsrox) in line 1244 of b4temp.c file. The corrected line is: pParam->BSIM4litl = sqrt(3.0 * 3.9 / epsrox * pParam->BSIM4xj * toxe) We would like to express our sincere thanks to all the users who gave us suggestions. We thank you for your support for BSIM and welcome your feedback on this latest release of BSIM4. Sincerely, BSIM Team UC Berkeley
