Hi, I am designing a photodiode (reverse-biased).
In CMOS technology, I would like to have untouched silicon as possible.
I am wondering what diode layer in layout do? With this layer, what actually happens? Or, just defining for simulation or so..?

Thanks,
 

Diode layer ?

I must admit I have no idea what you are asking for - but usualy diode layer is just a recognition layer for DRC/LVS/Extraction purposes. It does not define the diode itself on silicon.

diode layer is just for drc/lvs check, in order to tell the software this is a diode...
for photodiode,you can just ignore it,and us n+psub/p+nwwell/nwellpsub to build PD...
seems we are doing similar design,are you designing CIS?

the diode layer is just a flag layer to identify if there is a diode.

when producing MASK after tape out, it will no longer exist. there are just well/ diffusion/ poly and metal and so on.

Check your drc/LVS rule for purpose of diode layer, maybe it is just a symbol, maybe has some function for mask operation, such as "non siliside"..

I agree with this.It only appear at EXT for post-sim and LVS, not increaseing mask,I think.
