A semiconductor infrared detector comprising in the following order: a semiconductor substrate (1); a layer of electrically insulating material (2); and motifs (4) formed in a semiconductor layer (3), whereby said motifs (4) are formed from at least one island (7) that is connected to bridges (5, 6) which are connected to polarization electrodes (8, 9), whereby said bridges (5, 6) are lines having a most approximately constant width I¿p? and the islands (7) are zones having a width I¿i? that is greater than than that of the lines.

Détecteur infrarouge semi-conducteur qui comporte dans l'ordre: un substrat semi-conducteur (1); une couche de matériau électriquement isolant (2); des motifs formés (4) dans une couche de semi-conducteur (3), lesdits motifs (4) étant formés d'au moins un îlot (7) relié à des ponts (5, 6) eux-mêmes reliés à des électrodes de polarisation (8, 9) lesdits ponts (5, 6) étant des traits de largeur I¿p? la plus approximativement constante et les îlots (7) étant des zones de largeur I¿i? plus grande que celle des traits.
