Abstract: Process for encapsulating a micro-device in a cavity formed between one first and one second substrate, comprising at least the steps of: producing the micro-device in and/or on the first substrate, attaching and securing the second substrate to the first substrate, forming the cavity in which the micro-device is placed, producing at least one hole through one of the two substrates, called the drilled substrate, and leading into the cavity opposite a portion of the other of the two substrates, called the receiving substrate, depositing at least one getter material portion on said portion of the receiving substrate through the hole, hermetically sealing the cavity by closing the hole.

Abstract: A structure for encapsulating at least one electronic device, including at least one first cavity bounded by a support and at least one cap provided on the support and wherein the electronic device is encapsulated, at least one aperture passing through the cap and communicating the inside of the first cavity with at least one portion of getter material provided in at least one second cavity which is arranged on the support and adjacent to the first cavity, at least one part of said portion of getter material being provided on the support or against at least one outer side wall of the first cavity, the first cavity and the second cavity forming together a hermetically sealed volume.

Abstract: An installation and method for etching at least one wafer coated with an etch-ready, blank photosensitive layer is disclosed. In accordance with an embodiment, the wafer has thickness irregularities, wherein the wafer is arranged to be able to be submitted to irradiation-beam scanning, a sheet transparent to the radiation to which the photosensitive layer is sensitive covers the wafer, and a probe beam intended to reflect on the upper portion of the sheet perpendicularly to the irradiation beam spot on the photosensitive layer is provided.

Abstract: The invention relates to a method for diffusing metal particles included in a composite layer previously deposited on a substrate, said composite layer further including at least one dielectric matrix. According to this method, the diffusion of said metal particles towards said substrate is achieved by means of a plasma treatment.

Abstract: High-efficiency method and device, to produce coherent Smith-Purcell radiation. A conductive diffraction grating, delimited by two conductive walls, is used, and an electron beam is passed above the grating to generate the radiation. According to the invention, the speed of the electrons is sufficiently low in order that, in a diagram (wave number k, frequency f), the beam line (I) intersects a portion (V) of a branch of the dispersion relationship, located in the first Brillouin zone, and corresponding to the grating's fundamental mode, at a point (P) located outside the zone delimited by the light lines (III, IV), and the current density of the beam is sufficiently high to excite the grating's fundamental mode which is radiated towards the outside thereof.

Abstract: The invention relates to a device for mass detection of particles in a fluid medium, including an electromechanical oscillator (7), excitation means (9) fitted so as to cause the said oscillator to vibrate, a fluid supply circuit (5), and a fluid system (11) incorporated in the said oscillator, where the said fluid system (11) is in fluid communication with the fluid supply circuit (5), where the said fluid system (11) includes at least one trapping site (21) configured to trap a particle of interest according to the size of the said particle of interest.

Abstract: A continuous automated extraction system and method for physically extracting at least one liquid phase of a series of liquid microsamples which are taken beforehand in discrete packets, both in space and in time, and are in stored is provided. The method may include an extraction system having a centrifuge provided with a plurality of microholders, at least one of which is filled with the corresponding microsample and includes a filling upper portion that is extended by a separating lower portion of smaller cross section than that of the upper portion. Each filled microholder has a mass which is more than ten times the mass of this microsample, in such a way that it is possible to extract, by centrifugation, at a given instant, only a single microsample contained in a single microholder, or several microsamples contained in some or all of these microholders, progressively as the latter are filled.

Abstract: A cache memory associated with a main memory and a processor capable of executing a dataflow processing task, includes a plurality of disjoint storage segments, each associated with a distinct data category. A first segment is dedicated to input data originating from a dataflow consumed by the processing task. A second segment is dedicated to output data originating from a dataflow produced by the processing task. A third segment is dedicated to global constants, corresponding to data available in a single memory location to multiple instances of the processing task.
