Abstract: The invention concerns a method for marking a surface (S) by laser treatment, consisting of etching a plurality of patterns (M(0), M(1)) onto the surface by means of a laser source (2), said patterns being distributed across the surface according to a predefined tessellation of adjacent patterns, which involves: —etching each pattern from a corresponding virtual image generated in an image plane (20) of the laser source and physically reproduced by laser etching on the surface, in which each virtual image defines a frame physically reproduced on an area of the surface such that the corresponding etched pattern has an etched frame covering said area, the etched frames of adjacent patterns covering adjacent areas; and —the laser source is controlled in position between each etching of a pattern by means of a three-dimensional surface mapping system (3) coupled to the laser source; the method being remarkable in that it involves resetting the laser source, before etching each pattern, by matching up hook element

Abstract: A protective device for a male end of a component of a threaded tubular connection for drilling and working hydrocarbon wells is externally provided with at least one threading and includes a free terminal portion. The device includes i) a protector body produced in the form of a first sleeve and arranged to protect at least a portion of the external threading and the free terminal portion, ii) a sealing element for positioning in contact firstly with the component, at least at a portion located downstream of the external threading of the male end, and secondly with the protector body to provide a first seal downstream of the external threading, and iii) a fixing mechanism displacing the sealing element and/or protector body radially towards the component, defining open and closed positions of the device in which the sealing element and/or the protector body are respectively not in contact and in tight contact with the component. Further, the first seal is obtained in the closed position of the device.

Abstract: An integrated circuit is provided that comprises a substrate of silicon and an interconnect in a through-hole extending from the first to the second side of the substrate. The interconnect is coupled to a metallization layer on the first side of the substrate and is provided on an amorphous silicon layer that is present at a side wall of the through-hole, and particularly at an edge thereof adjacent to the first side of the substrate. The interconnect comprises a metal stack of nickel and silver. A preferred way of forming the amorphous silicon layer is a sputter etching technique.

Abstract: An integrated circuit (100) is provided that comprises a substrate (140) of silicon and an interconnect (130) in a through-hole extending from the first to the second side of the substrate. The interconnect is coupled to a metallisation layer (120) on the first side of the substrate and is provided on an amorphous silicon layer that is present at a side wall of the through-hole, and particularly at an edge thereof adjacent to the first side of the substrate. The interconnect comprises a metal stack of nickel and silver. A preferred way of forming the amorphous silicon layer is a sputter etching technique.
