Why leakage power increases when the scale is smaller?

Leakage power doubt

Hi, I've found an article and gone thru this chart :
**broken link removed**
Currently I'm dealing wif design using 0.13 technology, so i need not to worry much on leakage power. But it will be more and more critical when it goes below 0.1um.
The leakage power increases when the scale is smaller. I would like to know y, thanks.

Hi wakaka,

Is it possible for you to provide the article or link if it had any ?
This seems to be interesting...:|

Hi Wakaka
As the transistor scales down subthreshold current increases because of Short channel effects like DEBL, Gate leakage etc. At the same time we also try to put more logic into one single chip since the area is reduced because of smaller transistor. Hence the total power consumption as well as leakage increases as device scales down.

Hope this will clear your doubt

AS for the reason, I'm still not that clear.....
