Title (EN) METHODS AND APPARATUS TO REMOVE EPITAXIAL DEFECTS IN SEMICONDUCTORS
(FR) PROCÉDÉS ET DISPOSITIFS POUR ÉLIMINER DES DÉFAUTS ÉPITAXIAUX DANS DES SEMI-CONDUCTEURS
Abstract:
(EN) Methods and apparatus to remove epitaxial defects in semiconductors are disclosed. A disclosed example multilayered die structure includes a fin having a first material, where the fin is epitaxially grown from a first substrate layer having a second material, and where a defect portion of the fin is etched or polished. The disclosed example multilayered die structure also includes a second substrate layer having an opening through which the fin extends.
(FR) L'invention concerne des procédés et dispositifs pour éliminer des défauts épitaxiaux dans des semi-conducteurs. Une structure de matrice multicouche décrite à titre d'exemple comprend une ailette ayant un premier matériau, l'ailette étant formée par croissance épitaxiale à partir d'une première couche de substrat ayant un second matériau, et une portion de défaut de l'ailette étant gravée ou polie. La structure de matrice multicouche décrite à titre d'exemple comprend également une seconde couche de substrat ayant une ouverture à travers laquelle s'étend l'ailette.
