FinFET Fundamentals by Lam Research

Lam Research has published a tutorial on FinFETs basics that is very interesting for anyone who likes to understands the basics of FinFETs:

Transistors are at the heart of our cherished electronics. Millions, or even billions, of these tiny switches go to work for us when we check our mobile phones, use our computers, start our automobiles, or play on our gaming consoles. But what exactly are transistors and how do they work? And how have they changed over the years? Here we take a look at some transistor fundamentals, including the operation of a field-effect transistor (FET), as well as the FinFET technology inflection that is enabling even smaller, more powerful semiconductor chips.
