Electroplating a bare-die CPU.

[alligatorshapedpotato]

This is probably a 1000 IQ question.

 

I know that bare-dies are coated with a diffusion layer of silicon nitrite, but I have no idea exactly what would happen if I tried to electroplate the diffusion layer itself; I am not talking about a dipping based electroplating but a manual felt-pen type, with controllable, stabilized voltage levels.

 

Running electroplating-level voltage through the CPU seems like an absolutely incredibly stupid terrible idea that could easily kill a board, but it might not actually be harmful so here I am asking about it. Even if I go ahead ahead and test it, and it "seems" okay, it might actually not be so ideal.

 

Where would the electricity even go if applied directly to the diffusion layer?

 

Thanks in advance for your time answering a glue-huffing, pinecone eating question.

Well, the top of the silicon die isn't electrically conductive. If you laid a conductor on it and passed a current though it the CPU circuitry would still be electrically isolated.

 

Unless you cranked the voltage high enough to break the insulator barrier the CPU should remain untouched functionality wise.
