Hello,

I am doing layout with cadence virtuoso.

I drwaing poly and diffusion layers(utility) for density rule.

Is it possible to draw these layers on to the Pads? (pad contains only metal layers)

Thanks.

Some technologies prohibit "circuit under pad" and some promote it.
You'd have to get specific and look at your PDK's I/O construction rules.
Underlying topography should not bother the assembly process but
assembly "inputs" (like wedge bonding) can put strain on active devices
which either is, or looks like reliability degradation. A fabrication process
that allows "CUP" (circuit under pad) has to be qualified in concert with
a specific assembly recipe and vendor's control system.
