    Abstract: A configurable electronic circuit having configuration nodes is provided. Each of the configuration nodes is coupled to corresponding first circuitry that is non-modifiable during configuration and second circuitry that is modifiable during the configuration. The non-modifiable first circuitry selectively imposes one of at least a first potential and a second potential on the configuration node prior to configuration, and the modifiable second circuitry allows modification of the potential imposed on the configuration node by the non-modifiable first circuitry. In a preferred embodiment, the modifiable second circuitry includes at least one fuse that is in an intact state before configuration and that can be changed to a destroyed state after configuration. This enables a reduction in the number of fuses that have to be destroyed during the configuration of the circuit. Also provided is an information processing system that includes at least one configurable electronic circuit having configuration nodes.

    Abstract: A method for fabricating an integrated circuit. According to the method, a second dielectric layer is formed above a first dielectric layer, and holes and/or trenches are etched in the first and second dielectric layers. The holes and/or trenches are filled with metal in order to form electrical connection elements, and at least a third dielectric layer is formed. Holes and/or trenches are selectively etched in the third dielectric layer and the second dielectric layer with respect to the first dielectric layer and the elements, in order to control the depth of the etch. Additionally, there is provided an integrated circuit of the type having metallization levels separated by dielectric layers and metallized vias connecting lines of different metallization levels. The integrated circuit includes first and second metallization levels, first and second superposed dielectric layers located above the first metallization level, and a third dielectric layer located above the first and second dielectric layers. Further, at least one electrical connection element is provided in the third dielectric layer and passes through the second dielectric layer until it comes into contact with the first dielectric layer.

    Abstract: A micro-pipeline type asynchronous circuit and a method for detecting and correcting soft error. The asynchronous circuit records in a first recording unit a signal output by a calculation unit and then records in a second recording unit the same signal delayed by at least the duration of the pulse of a soft error. The recorded signals then are compared in a comparer circuit. If they are identical, no soft error has been detected and the output signal is recorded after another delay that is longer than the pulse duration of the soft error, and a request signal is transmitted to a control unit of a next logic stage with a delay twice as long as the pulse duration of a soft error.

    Abstract: A method for making a MOS transistor includes forming a first gate within a silicon-on-insulator substrate, forming a semiconductor channel region transversely surmounting the first gate, and forming semiconductor drain and source regions on each side of the channel region. The semiconductor channel region and drain and source regions may be produced by epitaxy on an upper surface of the first gate. The channel region may be isolated from the upper surface of the first gate by forming a tunnel under the channel region and at least partially filling the tunnel with a first dielectric. The second gate is formed on the channel region and transverse to the channel region. The second gate may be separated from an upper surface of the channel region by a second dielectric.
