摘要:
A method of detaching two substrates at the embrittlement zone situated at a given depth of one of the two substrates. The method includes a separation annealing step implemented in a furnace, wherein the annealing includes a first phase during which the temperature changes along an upgrade allowing a high temperature to be reached and annealing at this high temperature to be stabilized, and a second phase during which the temperature changes along a downgrade, at the end of which the furnace is opened to unload the substrates from the furnace. The second phase is regulated so as to minimize temperature inhomogeneities such as cleavage defects at the detached surfaces of the substrates when the furnace is opened.

A method for minimizing defects when transferring a useful layer from a donor wafer to a receptor wafer is described. The method includes providing a donor wafer having a surface below which a zone of weakness is present to define a useful layer to be transferred, molecularly bonding at a bonding interface the surface of the useful layer of the donor wafer to a surface of the receptor wafer to form a structure, heating the structure at a first temperature that is substantially higher than ambient temperature for a first time period sufficient to liberate water molecules from the bonding interface, with the heating being insufficient to cause detachment of the useful layer at the zone of weakness, and detaching the useful layer from the donor wafer.
摘要:
A method for detaching a layer from a wafer. A weakened zone is created in the wafer to define the layer to be detached and a remainder portion of the wafer, such that the weakened zone includes a main region and a localized super-weakened region that is more weakened than the main region. Detachment of the layer from the remainder portion of the wafer is initiated at the super-weakened region such that the detachment properties to the main region to detach the layer from the remainder portion.

The invention relates to a method of forming a structure comprising a thin layer of semiconductor material transferred from a donor substrate onto a second substrate, wherein two different atomic species are co-implanted under certain conditions into the donor substrate so as to create a weakened zone delimiting the thin layer to be transferred. The two different atomic species are implanted so that their peaks have an offset of less than 200 Å in the donor substrate, and the substrates are bonded together after roughening at least one of the bonding surfaces.

摘要:
A method for reclaiming a surface of a substrate, wherein the surface, in particular a silicon surface, comprises a protruding residual topography, comprising at least the layer of a first material. By providing a filling material in the non-protruding areas of the surface of the substrate and the subsequent polishing, the reclaiming can be carried out such that the material consuming double-sided polishing step used in the prior art is no longer necessary.
摘要:
The invention relates to a method for routing a chamfered substrate, having applications in the field of electronics, optics, or optoelectronics, which involves depositing a layer of a protective material on a peripheral annular zone of the substrate preferably with the aid of a plasma, partially etching the protective material with the aid of a plasma, so as to preserve a protective ring of the deposited material on the front face of the substrate, this ring located at a distance from the edge of the substrate, so as to delimit an accessible peripheral annular zone, etching a thickness of the material constituting the substrate to be routed, preferably with the aid of a plasma that is level with the accessible peripheral annular zone of the substrate, and removing the ring of protective material preferably with the aid of a plasma.
