How the Ground Plane implantation is performed without damaging (and w/o varying the undoped nature) the top Si (8-10 nm) in FDSOI technology ?

It is a general practice to introduce Ground Plane in FDSOI devices under the BoX. The Ground Planes are introduced by Ion Implantation through Top Si layer and Buried Oxide. I wanted to know that...

Dudley J Benton Popular answer

I wrote a program that solves potential flow (i.e., streamlines, magnetic fields, etc.) using the boundary element method. It's very fast and it creates the graphics files automatically for velocity vectors and flood-fill contours. It comes with 8 example input files as well as GIFs of the vectors and streamlines. The plot program to display the results is also included. Here's a link to the zip file. I have a bunch of free software at the second link that you're more than welcome to use.
