A device for detecting at least one substance of a fluid includes at least one piezo-acoustic resonator with at least one piezo layer, an electrode arranged on the piezo-electric layer, at least one other electrode arranged on the piezo-electric layer and a surface section used for sorption of the substance of the fluid. The piezo-electric layer, the electrodes and the surface section are disposed in such a way that electric control of the electrodes leads to an oscillation of the resonator at a resonance frequency which depends upon the amount of the substance which is sorbed on the surface section. The thickness of the pioelectric layer is in the region of 0.5 to 20 μm and the resonance frequency of the oscillation ranges from 500 MHz to 2 GHz. The device is a mass sensor with a piezo-acoustic high-frequency thin film resonator.

An array structure of single-level poly NMOS EEPROM memory cells and method of operating the array is discussed implemented in a higher density embedded EEPROM layout that eliminates the use of high voltage transistors from the array core region. If they are utilized, the high voltage transistors are moved to row and column drivers in the periphery region to increase array density with little or no added process complexity to allow economic implementation of larger embedded SLP EEPROM arrays. During program or erase operations of the array, the method provides a programming voltage for the selected memory cells of the array, and a half-write (e.g., mid-level) voltage to the remaining unselected memory cells to avoid disturbing the unselected memory cells of the array.

There is provided a system and process for detecting biomolecular interaction on a substrate having a biomolecule immobilized on a surface of the substrate. The system and process incorporate a scanning Kelvin microprobe (SKM) capable of analyzing surface topography as well as a contact potential difference image signal. Also provided is the use of SKM in measuring and analyzing biochemical molecular interactions between a probe bound to the surface of the substrate, and a target suspected to be present in a liquid sample. One of the probe and target combination is a biomolecule such as a nucleic acid, a polypeptide, or a small molecule, and an antibody antigen combination may be used.
