I want to add some pad to my tsmc18rf tech file. I have tried both methods : by copying the dvio library that contains the sig_pad library, into the tsmc18rf. and by adding those libraries from the tools\library path editor\... . but there was no changes in my lsw window. and there was no pad in it's list. I don't know how to do it. and i have an other question. how to use these pads in layout? and how to connect them to the circuit? my circuit is a front-end and i'm working by assura.
thanks before.

Hi
thank you for your  reply .but before i read that the pad is made up all of metals and not  only the top one. my pad is sig_pad and i want to connect it to the input of my lna and i don't know how to do it. please clarify it more. i'm sorry. i am doing it for the first time and i have no experience in  rf layout. i explored the internet and the books . but i couldn't find any thing about what i want to know. and please introduce me an useful book about the rf layout  if you know one.
