1. An integrated microreactor comprising:
- a) a body of semiconductor material;
b) a buried channel in said body and having walls and a coating layer of insulating material coating said walls;
c) a diaphragm upwardly closing said channel, said diaphragm comprising a semiconductor layer completely encircling mask portions of insulating material, wherein said semiconductor layer is surrounded by an oxide layer;
d) a structural layer extending on top of said body and said diaphragm;
e) a reservoir layer extending on top of said structural layer and a first reservoir extending through said reservoir layer as far as said structural layer; and
f) a first aperture extending through said structural layer and connecting said first reservoir with said channel.
