摘要:
A multi-layer substrate has a front face with external pads. An integrated-circuit chip is positioned inside of the multi-layer substrate. An electronic and/or electric component is also positioned inside of the substrate above the integrated-circuit chip. An electrical connection network is formed in the multi-layer substrate to selectively connect the integrated-circuit chip and component together and to the external pads. A first screen is positioned within the multi-layer substrate between the integrated-circuit chip and the electrical connection network, this first screen being connected by vias to the external pads. A second screen is position on a top (external) surface of the multi-layer substrate above the component and electrical connection network, this second screen being connected by vias to the external pads. The integrated-circuit chip is position to be inside the first and second screens.

摘要:
An electrical device includes two supports for electronic components. A first support bears at least one input terminal, an electric circuit connected to the input terminal and a voltage limiter. A second support bears at least one external connection terminal. The external connection terminal is connected to the input terminal by a capacitor, and the link between the capacitor and the external connection terminal includes a node connected to the voltage limiter device so as to limit a voltage between said node and a reference point of the electric circuit.
摘要:
A device for protecting an electronic circuit against electrostatic discharges comprises a connection terminal linked to one terminal of the electronic circuit, two tracks respectively linked to two terminals of an electrical power source supplying the electronic circuit, and two diodes each one linked to one of the two tracks and to the connection terminal. The two diodes are placed on a surface of a substrate. The connection terminal is carried by the substrate and is located above part of at least one of the two diodes with respect to the substrate.
