Abstract: A heterogeneous integration chip of a micro fluid actuator is disclosed and includes a first substrate, a first insulation layer, a first conductive layer, a piezoelectric layer, a second conductive layer, a second substrate, a control element, a perforated trench and a conductor. The first substrate includes a first chamber. The first insulation layer is disposed on the first substrate. The first conductive layer is disposed on the first insulation layer and includes an electrode pad. The piezoelectric layer and the second conductive layer are stacked on the first conductive layer sequentially. The second substrate is assembled to the first substrate through a bonding layer to define a second chamber and includes an orifice, a fluid flowing channel and a third chamber. The control element is disposed in the second substrate. The perforated trench filled with the conductor is penetrated from the electrode pad to the second substrate.

Abstract: A miniature fluid actuator is disclosed and includes a substrate, a chamber layer, a carrying layer and a piezoelectric assembly. The substrate has an inlet. The chamber layer is formed on the substrate and includes a first chamber in communication with the inlet, a resonance layer and a second chamber. The resonance layer has a central aperture in communication between the first chamber and the second chamber. The carrying layer includes a fixed region formed on the chamber layer, a vibration region, a connection portion and a vacant. The vibration region is located at a center of the fixed region and corresponding to the second chamber. The connection portion is connected between the fixed region and the vibration region. The vacant is formed among the fixed region, the vibration region and the connection portion. The piezoelectric assembly is formed on the vibration region.

Abstract: A manufacturing method of miniature fluid actuator is disclosed and includes the following steps. A flow-channel main body manufactured by a CMOS process is provided, and an actuating unit is formed by a deposition process, a photolithography process and an etching process. Then, at least one flow channel is formed by etching, and a vibration layer and a central through hole are formed by a photolithography process and an etching process. After that, an orifice layer is provided to form at least one outflow opening by an etching process, and then a chamber is formed by rolling a dry film material on the orifice layer. Finally, the orifice layer and the flow-channel main body are flip-chip aligned and hot-pressed, and then the miniature fluid actuator is obtained by a flip-chip alignment process and a hot pressing process.
