Method for producing multilayers on a substrate
First Claim
1. Method for producing a multilayer on a receiving substrate, which method includes the following steps:
- the formation of an initial substrate comprising a first material layer formed on the surface of a supporting substrate made of a second material, wherein the first material has an evaporation temperature higher than the evaporation temperature of the second material, molecular adhesion bonding of the surface of the initial substrate comprising the first material layer to the bonding surface of a receiving substrate to obtain a bonded structure, partial removal of the initial substrate so as to leave a thin film of said second material on the first material layer, evaporation of the second material thin film with a selective stop on the first material layer, which evaporation is carried out at a temperature higher than or equal to the evaporation temperature of the second material, and lower than the evaporation temperature of the first material, growth of at least one layer from the first material layer bonded to the receiving substrate, with the evaporation step and the growth step being carried out in the same technological apparatus.
