Homebrew PCBs

I always thought they used very thin PCBs and glued them together.  i.e. to make a 3 layer board you make a double sided board and a single sided board and glue them together.

Anyone else know for sure?

Subject: [Homebrew_PCBs] How are multi-layer PCBs made?

                           Hi guys,
 
 Last night I was thinking about 3 and 4 layer PCBS and can't seem to 
 figure out how they do them.
 
 Single sided - easy, we all do that.
 Double sided - easy, we do that as well with some alignment issues.
 
 But once you get beyond that, I realize a different manufacturing 
 process has to be done to get the layers.  How do they do it?
