Abstract: A high-sensitive micro cantilever sensor and a method for fabricating the same which is able to reduce size of a system greatly using a functional thin film has a structure in which an upper substrate comprising one or two piezoelectric cells including a cantilever, a piezoelectric layer formed on lower or upper surface of the cantilever, and electrodes formed on upper and lower surfaces of the piezoelectric layer is attached to a lower substrate including a cavity of an even depth by contacting the lower surface of the piezoelectric cell on the upper substrate with the cavity surface of the lower substrate.
