2>If the current thru the poly is 20nA and the contact can take a max current of 10nA how would u overcome the problem?

Thanks in Advance!

ECL is fastest , refer any digital book for explanation

2- If the current thru the poly is 20nA and the contact can take a max current of 10nA how would u overcome the problem?

put 2 via's , that the solution. practically it is desirable to add to more than 2 vias so that all the EM , yield & reliabilty issues are also taken care
