CSP means "chip scale package". It really is just the chip, some lead balls 
on top of it (the top side is where the logic is, it's then upside down on 
the board), and some black coating to avoid light getting on the chip.  
That's all.  A CSP package is a chip directly put on a board, without bond 
wires and such.

Yes.  It becomes harder with the parts becoming smaller.

Quite unlikely.
