Publication number: 20100155950Abstract: A metal barrier is realized on top of a metal portion of a semiconductor product, by forming a metal layer on the surface of the metal portion, with this metal layer comprising a cobalt-based metal material. Then, after an optional deoxidation step, a silicidation step and a nitridation step of the cobalt-based metal material of the metal layer are performed. The antidiffusion properties of copper atoms (for example) and the antioxidation properties of the metal barrier are improved.Type: ApplicationFiled: August 7, 2009Publication date: June 24, 2010Applicant: STMicroelectronics S.A.Inventors: Laurin Dumas, Cécile Jenny, Pierre Caubet

Publication number: 20100133634Abstract: A semiconductor product includes a portion made of copper, a portion made of a dielectric and a self-aligned barrier between the copper portion and the dielectric portion. The self-aligned barrier includes a first copper silicide layer comprising predominantly first copper silicide molecules, and a second copper silicide layer comprising predominantly second copper silicide molecules. The proportion of the number of silicon atoms is higher in the second silicide molecules than in the first silicide molecules. The second copper silicide layer is positioned between the copper portion and the first copper silicide layer. A nitride layer may overlie at least part of the first copper silicide layer.Type: ApplicationFiled: January 28, 2010Publication date: June 3, 2010Applicant: STMicroelectronics S.A.Inventors: Pierre Caubet, Nicolas Casanova

Patent number: 6688846Abstract: A flexible rod (20) is articulated at a first end to a control ring (30) and is fixed at a second end to a pivot of a blade (10) that is to be controlled. At this second end, it is held so that it can rotate without play on the blade pivot by a holding device (44; 52; 54). The articulation device comprise a pivot (24) passing through a first orifice (22) pierced in this first end and engaged in a radial housing (28) of the control ring, the pivot being held in position by a locking ring (34) which has openings (36) for the passage of this pivot and which slides on this control ring. The fixing device comprise a fixing screw (40) passing through a second orifice (38) pierced in the second end of the rod and introduced into a hole (42) of the pivot of the blade that is to be controlled.Type: GrantFiled: September 17, 2001Date of Patent: February 10, 2004Assignee: Snecma MoteursInventors: Jean-Pierre Caubet, Antoine Jean, Jacky Naudet, Gabrijel Radeljak, Sébastien Riccioz
