| 摘要 |
A method for producing a structure having an ultra thin buried oxide (UTBOX) layer by assembling a donor substrate with a receiver substrate wherein at least one of the substrates includes an insulating layer having a thickness of less than 50 nm that faces the other substrate, conducting a first heat treatment for reinforcing the assembly between the two substrates at temperature below 400° C., and conducting a second heat treatment at temperature above 900° C., wherein the exposure time between 400° C. and 900° C. between the heat treatments is less than 1 minute and advantageously less than 30 seconds.
