Publication number: 20230326884Abstract: An integrated circuit device is disclosed, the device comprising a protective layer and a protected circuit on a substrate, the protective layer being configured to protect the protected circuit by absorbing laser radiation targeted at the protected circuit through the substrate. The device may be configured such that removal of the protective layer causes physical damage that disables the protected circuit. The device may comprise intermediate circuitry protruding into the substrate between the protective layer and the protected circuit, wherein the physical damage that disables the protected circuit is physical damage to the intermediate circuitry. The device may comprise detection circuitry configured to detect a change in an electrical property of the device indicative of removal of the protective layer, and, in response to detecting the change in the electrical property, cause the protected circuit to be disabled.Type: ApplicationFiled: April 12, 2023Publication date: October 12, 2023Applicant: Nagravision SAInventors: Stephane JULLIAN, Pascal AUBRY

Patent number: 7038161Abstract: The invention provides a welding device (10) using a power laser beam (22), the device (10) being miniaturized, the device (10) being suitable for being moved very close to the surface (52a) of the part (52) to be welded and of reaching welding zones that are difficult to access, but without vapor and particles of molten metal (56) being capable of penetrating into the inside and dirtying the optical components (28, 48, 46). Such a device is remarkable in that it includes a feed (26) of gas under pressure suitable for producing a primary flow of gas (50) leaving via the front opening (20) together with the laser beam (22), and in that it also includes a nozzle (60) connectable to a source of gas under pressure, said nozzle (60) producing a secondary flow of gas (62) sweeping the front opening (20) transversely, thereby deflecting the primary flow of gas (50) laterally.Type: GrantFiled: July 4, 2002Date of Patent: May 2, 2006Assignee: Snecma MoteursInventors: Pascal Aubry, Thierry Dubois, Sophie Hertmanowski, Hervé Launais
