Definitions
- a second possibility would be to implement a Smart Cut TM layer transfer by creating an embrittlement zone in a quartz donor substrate, LiNb0 3 or LiTa0 3 so as to delimit the thin layer to be transferred, by bonding said layer to be transferred onto a support substrate and detaching the donor substrate along the embrittlement zone so as to transfer the thin layer onto the support substrate.
- the creation of the zone of weakening by ion implantation in the donor substrate damages the transferred layer and deteriorates its piezoelectric properties.
- the healing methods including annealing) known for the transfer of silicon layers do not always make it possible to completely repair the piezoelectric layer, because of the complex crystalline structure of said layer and the mechanisms of damage which seem different from those which intervene in silicon.
- the weakening zone may be formed by ion implantation in the donor substrate.
- Another object relates to a substrate for a microelectronic device, photonic or optical, comprising a monocrystalline piezoelectric layer on a receiving substrate, characterized in that the piezoelectric layer has a first portion located at the interface with the receiving substrate, and a second portion extending from the first portion and in that the second portion has characteristics different from those of the first portion.
- a donor substrate 100 of the piezoelectric material is provided and, by ion implantation (schematized by the arrows), an embrittlement zone 101 is formed which delimits a piezoelectric single crystal layer 102 to be transferred. , intended to form the seed layer.
- the donor substrate 100 is represented solid but, as indicated above, it could possibly be composite.
- the implanted species are hydrogen or helium, alone or in combination.
- detachment of the donor substrate 100 is carried out along the embrittlement zone 101. Such detachment may be caused by any means known to those skilled in the art, for example thermal, mechanical, chemical, etc. .
- the remainder of the donor substrate, which may optionally be recycled, is then recovered, which makes it possible to transfer the layer 102 onto the recipient substrate 1 10.
- a surface portion of the transferred layer for example by mechanical polishing and / or chemical etching. This removal of material is intended to eliminate any defects related to implantation and detachment.
- a layer 102 is obtained. thinned on the receiving substrate 1 10, which will serve as a seed layer in the next step.
- the transferred layer 102 of Figure 3C can be used directly as a seed layer.
- a substrate is obtained for a surface acoustic wave device or a volume acoustic wave device, which comprises a receiver substrate 1 10 and a monocrystalline piezoelectric layer. 10 on said receiver substrate 1 10.
- a substrate may also be useful for other applications, for example for photonics and integrated optics.
- a first electrode is deposited on the free surface of the layer 102 to be transferred from the piezoelectric donor substrate, this first electrode (referenced 13 in FIG. finding buried in the final stack.
- a second electrode is deposited on the free surface of the piezoelectric layer 10, opposite to the first electrode.
- Another option is to transfer the piezoelectric layer to a final substrate as mentioned above and to form the electrodes before and after said transfer.
