I vaguely remember a newspaper account of this where the channels consist
of amorphous silicon (the Ovshinsky technology) which are made conducting
or not by an applied voltage. Chips are glued on top of the wafer - sort
of surface mount - and the wafer serves as the circuit board. It is alleged
to be a neat way of fabricating very small "boards".  The conduction of
the channels can be changed for EC's.

The above is a recollection of a newspaper article, so don't expect accuracy.
