Abstract: A method for the determination of the diffusion tensor anisotropy or the surface energy anisotropy that does not require the formation of particular structures, and that is capable of being performed in cases of moderate-amplitude perturbations. The invention relates to measuring the temporal evolution of natural or artificial roughnesses, and analyzing the results in the firm of the 2D power spectral density for moderate-amplitude perturbations typically characterized by amplitude/wavelength ratios of the perturbation for a spatially defined perturbation having two wavelengths along two orthogonal directions, the ratios typically being less than 0.3.

Abstract: The invention relates to a method for forming microcavities (118) of different depths in a layer (102) based on at least an amorphous or monocrystalline material, comprising at least the following steps in which: at least one shaft and/or trench is formed in the layer (102) so as to extend through one face (101) thereof, such that two sections of the shaft and/or the trench, in two different planes parallel to the face (101), are aligned in relation to one another along an alignment axis forming a non-zero angle with a normal to the plane of said face (101); and the layer (102) is annealed in a hydrogenated atmosphere so as to transform the shaft and/or trench into at least two microcavities (118).

Abstract: The invention relates to the field of micro- and nanotechnologies. In these techniques, it is sometimes necessary to glue several structures face to face and it is important to be able to check the alignment of the structures. A new method for measuring alignment, which comprises the following operations, is proposed for this purpose: activation of a heating element placed on the surface of the first structure, generation of electronic signals representative of a distribution of temperatures, on the basis of an array of temperature sensitive elements placed on the surface of the second structure, determination of a relative position of the heating element with respect to the array of sensitive elements, therefore of the first structure with respect to the second, on the basis of the distribution of temperatures, in a calculation circuit receiving the electronic signals engendered in the array of sensitive elements.

Abstract: A method for forming a wire in a layer based on a monocrystalline or amorphous material. The method forms two trenches in the layer, crossing through one face of the layer, separated from each other by one portion of the layer, by an etching of the layer on which is arranged an etching mask, and anneals, under hydrogenated atmosphere, the layer, the etching mask being maintained on the layer during the annealing. The depths and widths of the sections of the two trenches, and the width of a section of the portion of the layer, are such that the annealing eliminates a part of the portion of the layer, the two trenches then forming a single trench in which a remaining part of the portion of the layer forms the wire.
