Title
(EN) METHOD AND APPARATUS TO INCREASE RADAR RANGE
(FR) PROCÉDÉ ET APPAREIL PERMETTANT D'AUGMENTER UNE PORTÉE DE RADAR
Abstract
(EN) An integrated radar circuit comprising: a first substrate, of a first semiconductor material, said first substrate comprising an integrated transmit and receive radar circuit; a second substrate, of a second semiconductor material, said second substrate comprising at least one through-substrate cavity having cavity walls; at least one discrete transistor chip, of a third semiconductor material, said at least one discrete transistor chip having chip walls and being held in said at least one through-substrate cavity by a metal filling extending from at least one cavity wall to at least one chip wall; a conductor on said second substrate, electrically connecting a portion of said integrated transmit and receive radar circuit to a discrete transistor on said at least one discrete transistor chip.
(FR) La présente invention concerne un circuit radar intégré qui comprend : un premier substrat, d'un premier matériau semi-conducteur, ledit premier substrat comprenant un circuit radar de transmission et de réception intégré; un second substrat, d'un deuxième matériau semi-conducteur, ledit second substrat comprenant au moins une cavité de substrat traversant ayant des parois de cavité; au moins une puce de transistor discret, d'un troisième matériau semi-conducteur, ladite ou lesdites puces de transistor discret présentant des parois de puce et étant maintenues dans ladite ou lesdites cavités de substrat traversant par un remplissage métallique s'étendant à partir d'au moins une paroi de cavité jusqu'à au moins une paroi de puce; un conducteur sur ledit second substrat, raccordant électriquement une partie dudit circuit radar de transmission et de réception intégré à un transistor discret sur ladite ou lesdites puces de transistor discret.
