Hey all, I hope you're doing ok. I have some questions regarding the BEOL stack: 1) where exactly does the inductors go? At the skywater-pdk page it doesn't show a specific layer for it, however there are design rules for it. And is its metal copper or aluminum? 2) what about the polyimide layer? Where can I find it's electrical and physical parameters? (I'm concerned about thickness, dielectric constant and loss tangent). 3) are these two options readily available or do I need specific markers or whatever to enable them? (And out of passing curiosity, what purpose the LI serves that M1 can't do, since M1 has much better electrical conductivity than LI?) Thanks in advance :)
