The present invention particularly relates to a method for physical vacuum deposition of a coating (R) comprising at least one material (M) on at least a portion of a front face () of a support (), said at least one material (M) originating from an evaporation source or an atomisation source (), wherein: —use is made of a support (), at least a portion of the front face () of which is smooth, that is to say, does not have any roughness and/or reliefs and/or recesses; —said vacuum deposition is carried out while varying the thickness distribution of the material (M) on said front face (), that is, while progressively varying the thickness deposited, from a central region () in the direction of at least one lateral region () contiguous to the central region (), without modifying the position of the evaporation source or atomisation source () of the material particles (M).

The present invention relates in particular to a security element () for a valuable document, which comprises an array (R) of at least two contiguous or adjacent lines (&#x2033;), at least one of these lines () being raised and having two opposing and at least partially inclined sides () that each originate along one of the longitudinal and opposing edges () of the line (), characterised by the fact that the two opposing inclined flanks () meet at a single, uninterrupted, sinuous junction area (), that extends in the longitudinal direction of the line (), the sides () having no discontinuities or interruptions at least in the longitudinal direction.

Security element for a valuable document, method for producing same and valuable document that comprises it

An assembly comprising a complex transparency device, i.e. a refractive and/or diffractive device acting on the light phase, and at least one array of micro-images, wherein: the complex transparency device comprises a periodical two-dimensional array formed from individual 'pupils,' wherein each pupil comprises a micro-optical device, at least some of the micro-optical devices having a non-centered optical axis, and at least some of the micro-optical devices positioned non-periodically with variable off-setting of the optical axis thereof with the array; the array of micro-images comprising as many micro-images as micro-optical devices; each micro-image has a contour identical to that of the associated pupil and a surface which is at the most identical to that of the associate pupil; and each micro-image is sub-divided into at least one thumbnail image such that when the transparency device is positioned facing the array of micro-images, and an observer observes the array through the transparency device, the observer sees, at least in a given direction of observation, an image which is reconstructed by the combination of the thumbnail images associated with the direction, wherein within the same subdivision, certain thumbnail images, form 'firsts group' and are distributed such that when the transparency device is positioned facing the array of micro-images, the thumb-nail images are respectively arranged according to the optical axis of the associated micro-optical device.

Assembly consisting of a complex transparency device and at least one array of micro-images, as well as a security document comprising same

Method for mounting an electronic component, such as a silicon chip, on a support which consists in: providing an electronic component () having connection pads, whereof one predetermined pad (A) is provided with a bump (); providing a support having () to the predetermined pad via the bump; aligning the predetermined pad provided with the bump with the terminal; contacting the bump and the terminal and assembling them in specific temperature and pressure conditions. Prior to contacting and fixing the bump and the terminal, the surface of the terminal is covered with an insulating layer (), the insulating layer being a material selected so as to be traversed by the bump in the temperature and pressure conditions.
