Considering that these sections of the MOSFET are one solid piece, that's impossible.

To make the Gate, Source and Drain of a FET, one takes a solid chunk of Silicon, and adds small amounts of special impurities by painting it on to the outside, then baking in an oven to get the 'paint' to soak into the silicon.

While the actual process is quite a bit more complex, this explanation will give you the right idea as to how it is done.
