Definitions

  • a plasma gas when processing a single crystal silicon substrate, when oxidizing the surface, plasma of oxygen gas, when not oxidizing, hydrogen gas, argon gas, or a mixed gas thereof or hydrogen gas and helium gas. Examples thereof include mixed gas.
  • any gas may be used.
  • a single crystal silicon substrate and / or a handle substrate is placed in a chamber into which air is introduced, and after introducing a plasma gas such as nitrogen gas or argon gas, high-frequency plasma is generated, The surface is subjected to ozone treatment by converting atmospheric oxygen into ozone. Either or both of plasma treatment and ozone treatment can be performed.

Abstract

La présente invention concerne un substrat de silicium sur isolant (SOI), l'occurrence de craquage provoqué par la différence des coefficients de dilatation thermique entre un substrat de manipulation et un substrat de silicium monocristallin ou analogue pouvant être empêchée dans ledit substrat. L'invention porte en outre sur un procédé de production d'un substrat de SOI, qui comprend les étapes suivantes : une étape d'implantation d'un ion hydrogène ou d'un ion de gaz rare dans une surface d'un substrat de silicium monocristallin qui sert de substrat donneur, pour former une couche à ion implanté ; une étape de soumission du substrat donneur doté de la couche à ion implanté à un premier traitement thermique ; une étape de soumission de la surface à ion implanté du substrat donneur ayant été soumis au premier traitement thermique et/ou d'une surface d'un substrat de manipulation à un traitement d'activation de surface ; suite au traitement de l'activation de surface, une étape de liaison de la surface à ion implanté du substrat donneur à la surface du substrat de manipulation ; une étape de soumission des substrats liés à un second traitement thermique ; et une étape de déstratification consistant à appliquer un impact mécanique à la couche à ion implanté des substrats liés qui ont été soumis au second traitement thermique, pour entraîner la déstratification des substrats liés dans le sens de la couche à ion implanté d'hydrogène, provoquant ainsi le transfert d'une mince pellicule de silicium sur le substrat de manipulation.
