Hello, we are trying to do a layout for a university project and we are wondering how we should connect cap_mim_m3 in the sky130 process? On metal 4 (yellow) there is a both a big block and also a thin strip as well. Should we connect the wire to both, only the big part or only the thin part?

@shibu I think the thin part on the right has a via3 connection from metal4 to metal3, right? If so, it’s the connection to the bottom plate - you can either connect the bottom plate to metal4 on the narrow strip, or anywhere else with metal3. The top metal4 plate can be connected with regular metal4.

Ah, thank you! Makes sense. Now I understand the picture from the docs
Found also a nice image and explanation here (posting in case anyone else will have a similar issue) https://www.ansys.com/blog/difference-between-mom-mim-mos-capacitor
