Abstract: A method for depositing particles onto a substrate, or a running substrate, including: (a) making a compact film of particles floating on a carrier liquid provided in a transfer area having an outlet of particles laid out facing the substrate; (b) depositing a substance on the compact film of particles, in the transfer area; (c) transferring, through the outlet of particles and onto the substrate, the compact film of particles coated with the substance; and then (d) removing the substance to carry away with the substance the particles of the film which adhere to the substance, to generate at least one recessed area within the film deposited on the substrate.

Abstract: A method for transferring objects onto a substrate, or running substrate, the objects to be transferred being placed in a transfer area containing a carrier liquid forming a conveyor, the objects being held by a compact film of particles floating on the carrier liquid of the transfer area, within which the objects are displaced with the film of particles to be transferred onto the substrate, making at least one connector on at least one of the objects, the connector being made by a substance comprising a polymerizable compound, put in contact with the object arranged within the transfer area, and then by polymerization of the substance.

Abstract: A method of transferring objects onto a substrate, or a moving substrate, the objects to be transferred being placed in a transfer area including an inlet and an outlet spaced apart from one another by two lateral edges opposite one another, and holding a carrier liquid forming a conveyor, the objects being held by a compact film of particles floating on the carrier liquid of the transfer area, in which the objects are moved with the particle film to be transferred onto the substrate when they reach the outlet.

Abstract: A thermal management system configured to be installed between a heat source and a heat sink, including a first heat conductor and a second heat conductor, a thermal switch configured to allow or prevent thermal connection between the first and second heat conductors, the thermal switch including at least one thermally conductive material that can connect the first and second conductors by a change in its volume, and the thermal switch including a controller configured to transfer thermal energy to the phase-change material to change a connection state. The connection is made when the heat source goes above a critical temperature, since the connection enables a heat flux to be established between the heat source and the heat sink.

Abstract: A facility for depositing a film of ordered particles onto a moving substrate, the facility configured to allow deposition, onto the substrate, of a film of ordered particles escaping from a particle outlet of a transfer zone having a first width. The facility further includes an accessory device in a form of a deposit head, provided to seal the particle outlet and configured to allow the deposition, onto the substrate, of a film of ordered particles escaping from an end of a particle transfer channel of the deposit head, the end having a second width strictly lower than the first width.

Abstract: A facility for depositing a film of ordered particles onto a moving substrate, the facility including: a transfer area including an entry of particles and an exit of particles spaced apart from each other by two side edges facing each other, retaining a carrier liquid on which the particles float, a capillary bridge ensuring connection between the carrier liquid contained in the transfer area and the substrate, and a plurality of suction nozzles capable of attracting the particles towards its two side edges.

Abstract: In the field of photolithography systems designed to produce electronic components using the technique known as “lift-off” on a plane substrate comprising one or more plane photosensitive layers, a system uses a laser direct-write technique. It comprises optical or mechanical means configured such that the useful part of the optical beam is inclined on the plane of the photosensitive layers in order to create profiles with an inverted slope within said layers, the useful part of the optical beam being the part of the optical beam which effectively contributes to creating said profiles. In one preferred embodiment, the system comprises means for partial shuttering of the optical beam situated in the neighborhood of the focusing optics.

Abstract: The present invention relates to a process for manufacturing a segmented optical structure (100), comprising at least the steps consisting in: a) providing a substrate (1) having microwalls (2) on one of the faces (3) of said substrate, which microwalls form, when the substrate (1) is observed along an axis (X) perpendicular to said face, a plurality of concentric recesses (5); b) depositing at least one material (10; 10a; 10b; 10c) in at least one recess (5); c) bringing at least one part of the upper surface (11) of the material (10; 10a; 10b; 10c) deposited in step b) into contact with at least one liquid medium (30) which is capable of dissolving said material (10; 10a; 10b; 10c) and is substantially inert with respect to the microwalls (2) and to the substrate (1); and d) imposing a centrifugal force on the liquid medium (30) deposited in step c) so as to modify the distribution thereof on the upper surface (11) of the material (10; 10a; 10b; 10c) deposited during step b), the amount of liquid medium (30

Abstract: A method for depositing a layer of organized particles on a substrate. This method includes the steps of: controlled stirring of a bath including at least the particles and a mixture of solvents formed of at least 50% by volume of ethanol; dipping of the substrate into the stirred bath; and removal of said substrate from the stirred bath.

Abstract: A laser source includes a first optical element and a second optical element spaced apart from each other and defining a laser cavity therebetween. The laser cavity with a lasing material therein are capable of emitting an optical beam. The laser source also includes a guided optical element formed on a substrate. The guided optical element includes a mirror which is concave in at least one guide plane of an input guide area of the guided optical element. The mirror forms an extended laser cavity with the laser cavity. The guided optical element also includes a microguide associated with an optical output of the laser source. The microguide defines an output area of the guided optical element. The input guide area is capable of receiving the optical beam emitted by the laser cavity and capable of transmitting the optical beam to an adaptor guide area located between the input guide area and the microguide. The adaptor guide area is capable of guiding the optical beam to the microguide.
