  • System and method for identification of a reference integrated circuit for a pick-and-place equipment
    Patent number: 7629186
    Abstract: A method and a system of alignment of an integrated circuit chip pick-and-place equipment with an origin of a wafer supporting these circuits, comprising optically searching on the wafer at least one reference pattern formed, on manufacturing of the integrated circuits, in a reference chip, the reference pattern being different from optically-recognizable patterns of the other chips.

  • Semiconductor component for supplying, recirculating and demagnetizing an inductive load
    Patent number: 5612562
    Abstract: A semiconductor component for switching an inductive load, comprises first and second external terminals, first and second control terminals and a node. A vertical bipolar transistor has a base region and is disposed between the first external terminal and the node. A first vertical transistor is disposed between the node and the second external terminal. A zener diode and a second vertical transistor are connected parallel between the base and the node.

  • Circuit for detecting an open load
    Patent number: 5438286
    Abstract: A circuit for the detection of an open load for a power MOS transistor is designed to operate in a switching mode. The MOS transistor is partitioned into two transistors disposed in parallel. The second transistor has a resistance in the conductive state higher than the first transistor. The circuit includes circuitry for enabling only the second transistor when the current is within a low value range, and circuitry for detecting an open load when the circuit is operating within the low current range.
