leakage power in submicron technology

help me to find the leakage power of a digital NAND gate in 90nm and 65 nm technology with a HSPICE program .kindly provide the model files for the MOSFETS.Let me know the threshold voltages ,length ,width of nmos and pmos in the 90nm & 65 nm technologies.

: Second order effects in MOSFETs

Different textbooks give different opinions about second order effects of MOS characteristics. Please explain in simple words,what is meant by the second order effects and how they affect the working of a MOSFET.
