process simulator #344

Open joamatab opened 4 months ago

joamatab commented 4 months ago

How could we make a 3D process simulator integration from layout so that we can simulate the geometry after fabrication?

at the moment we can only do 2D process simulations with pyxs

note that pyxs (not sure about this new library) does not actually model fabrication in the way an actual process simulator would

From the creator: "you can put together process scripts that generate photo realistic cross sections. Which - used without care - may be grossly misleading. [...] Despite it's low visibility and obvious flaws, the project receives considerable attention by parts of the user community. Obviously, it is a great tool for teaching, layout comprehension and understanding device functionality and parasitic effects. But it may also be a waste of time. This is why I both love and hate it. "

EDIT: looking through the ViennaPS code, it does look like they are actually simulating etching/deposition chemistry like a true process simulator

it looks like they have a gds reader, which could be an easy starting point
