Claim 5:
6. The manufacturing method of the miniature fluid actuator according to claim 1, wherein the step (b) further comprises steps of:
(b1) forming the lower electrode layer by depositing a first metal material on the flow-channel main body;
(b2) forming the piezoelectric actuation layer by depositing a piezoelectric material on the lower electrode layer;
(b3) forming the upper electrode layer by depositing a second metal material on the piezoelectric actuation layer;
(b4) performing the photolithography process on each of the upper electrode layer, the piezoelectric actuation layer and the lower electrode layer sequentially to define patterns thereof; and
(b5) performing the etching process on each of the upper electrode layer, the piezoelectric actuation layer and the lower electrode layer with the pattern thereof, to obtain the actuating unit at the required size.
