Patent number: 8448494Abstract: An electronic microbalance made in a semiconductor body accommodating an oscillating circuit adjacent to a diaphragm. A stack formed by a first electrode, a second electrode, and a piezoelectric region arranged between the first and the second electrode extends above the diaphragm. Any substance that deposits on the stack causes a change in the mass of the microbalance and thus in the resonance frequency of a resonator formed by the microbalance and by the oscillating circuit and can thus be detected electronically. A chemical sensor is obtained by forming a sensitive layer of a material suitable for binding to target chemicals on the stack. The sensitivity of the microbalance can be increased by making the first electrode of molybdenum so as to increase the piezoelectric characteristics of the piezoelectric region.Type: GrantFiled: December 29, 2009Date of Patent: May 28, 2013Assignee: STMicroelectronics S.R.L.Inventors: Ubaldo Mastromatteo, Flavio Francesco Villa, Gabriele Barlocchi
