by making the layout of pads very accuratly and puting the guard ring in all diods and wells ..

 

[williamy]

firstly, you must comply to the rules of design;
and you can add the space between the well's overlap to well contact

Increase the no. of substrate contacts and decrease the distance at which they are placed for different devices.
