Hello! I am reading this thread about photodiode, I have done some layout of chips way back in 1997 about four chips from ROHM on a 250um process but that was long time ago. I only recall when you do the chip it should be coomplety symmetric, devices and pads.
I suggest if you can use the open source 130nm skywater, 180nm IHP, GF90nm process so we can collaborate how we can migrate these process to electric.
