    摘要: The invention relates to a method for manufacturing a film (12) on a support (20) having a non-flat surface, characterised in that it comprises:
    - the supply of a donor substrate (10) having a non-flat surface,
    - the formation of an embrittlement zone (11) in the donor substrate (10) so as to delimit said film (12) to transfer,
    - the formation of the support (20) by conformal deposition on the non-flat surface of the film (12) to transfer,
    - the detachment of the donor substrate (10) along the embrittlement zone (11), so as to transfer said film (12) onto the support (20).

    摘要: The invention relates to a method for the production of a single-crystal film (10), characterised in that it comprises the following successive steps: the provision of a donor substrate (100) comprising a piezoelectric material of composition ABO
    3 , wherein A consists of at least one element from among Li, Na, K, H, Ca, and B consists of at least one element from among Nb, Ta, Sb, V; the provision of a receiver substrate (110); the transfer of a so-called "seed layer" from the donor substrate (100) to the receiver substrate (110), by means of bonding the donor substrate to the receiver substrate such that the seed layer (102) is located at the bonding interface, and the subsequent thinning of the donor substrate (100) as far as the seed layer (102); the epitaxial growth of a single-crystal film (103) on the piezoelectric material ABO
    3 of the seed layer (102), said film having composition A'B'O
    3 , wherein: A' consists of at least one element from among Li, Na, K, H; B' consists of at least one element from among Nb, Ta, Sb, V; and A' is different from A or B' is different from B.

    摘要: L'invention porte sur un substrat de croissance (1) pour la formation de dispositifs optoélectroniques comprenant un support de croissance (2) et, disposée sur le support de croissance (2), un premier groupe d'îlots semi-conducteurs cristallins (3a) présentant un premier paramètre de maille et un deuxième groupe d'îlots semi-conducteur cristallin (3b) présentant un deuxième paramètre de maille, différent du premier. L'invention porte également sur un procédé de fabrication du substrat de croissance, sur un procédé de fabrication collective d'une pluralité de dispositifs optoélectroniques sur le substrat de croissance. Elle s'applique pour fournir un micro panneau monolithique de diodes électroluminescentes ou un micro-écran d'affichage.
