摘要:
The invention concerns a system wherein a storage layer (2) is arranged opposite an array of microtips (5). The storage layer (2) comprises a plurality of insulated conductive islands (3) adapted to store electric charges. Each microtip (5) comprises a high-permittivity element (6) integral with a transistor channel (7) connecting a source (8) and a drain (9). The channel (7) has a conductance capable of being modified by the electric field generated by the charge of the island (3) arranged opposite the high-permittivity element (6). The system may comprise an actuator for relative displacement of the storage layer (2) relative to the microtips (5). The system may include an array of electrodes for moving the charges from one island (3) to the other.

The invention relates to a method for obtaining a thin layer from a plate provided with a front side with a given relief and a rear side, said method comprising the following steps: a) a support handle comprising a side used as a bonding side is obtained; b) the front side of the plate is prepared such that it is partially planarised in order to obtain a bonding energy E0 lying between a first value corresponding to the minimum bonding energy compatible with the subsequent thinning stage and a second value corresponding to the maximum bonding energy compatible with the subsequent debonding operation, the bonding energy E0 being such that E0 = αE, E being the bonding energy which would be obtained if the front side of the plate was completely planarised, and α being the ratio of the partially planarised surface of the front side of the plate to the surface of the front side of the plate if it was completely planarised; c) the front side of the plate is bonded to the bonding surface of the support handle by means of molecular bonding; d) the plate is thinned, starting from its rear side, until the thin layer is obtained; and e) the thin layer is debonded from the support handle and transferred to a support.

The invention concerns a micro system for biological analysis for detecting analytes, for example antigens, in a sample: the micro system comprises a cell (1) provided with a fixed electrode (3) and a mobile electrode (5) along the XX' axis. The electrode(s) are covered with or capable of fixing a specific ligand of the analyte to be detected, for example an antibody. After a sample has been introduced in the cell with electrodes at a removed position, for example at a distance of 2 νm, the mobile electrode can be brought closer or can be made to oscillate between a removed position (2 νm) and a close position (0.1 νm) and a parameter (impedance, viscosity, contact force between the electrodes) representative of the formation of an analyte-ligand layer on the electrode(s) can be measured.
