Claim 25:
26. A method for fabrication of a three-way microvalve device comprising:
bonding first and a second pre-processed substrates, wherein one of the pre-processed substrates is a silicon-on-insulator (SOI) type of substrate and the first and second pre-processed substrates have pre-determined sized flow channels, and
providing a mechanical mechanism between the first and a second pre-processed substrates, the mechanical mechanism including multiple piezoelectric actuators and a spacer element that are attached to a rigid bridge element on one side of the multiple piezoelectric actuators and the spacer configured to open and close the device to the flow of fluids through the three-way microvalve device, and pre-determined sized inlet and outlet ports that are made into the first and a second pre-processed substrates prior to the first and a second pre-processed substrates being bonded to one another.
