[repost nanobuff] On compact modeling

Posted on June 27, 2013 on nanobuff
"While the modeling industry is full of software solutions for all sorts of things in the operation of electronics from the very low to the very high level, there seems to be very sparse tools for simulating radiation effects. This would be normal if there was little interest or public research on the subject, but that is not the case. The models are out there, most of the basic concepts have been examined lots of decades ago, so what is stopping the industry? I really don’t know and I will not even try to answer.

Having said that, I would also like to state that compact modelling, in the case of radiation effects, is at least beneath me. I recently found this old compact modelling project. It is like a plugin to the Silvaco software. How would a compact modelling platform work in the ever-reducing dimensions of today? Things get fairly uncertain below 0.1 µm gate lengths. We need 3D, we need quantum models etc. just for the operation. And for the radiation part? That is now a materials science problem, I guess. And if you decide to go Monte Carlo, that’s even more demanding. The problem seems to be a “chicken and egg” one. We need more processing power to be able to simulate our next generation electronics that will give us more processing power."
