Patent number: 10112827Abstract: The invention is a process for producing an electromechanical device including a movable portion that is able to deform with respect to a fixed portion. The process implements steps based on fabrication microtechnologies, applied to a substrate including an upper layer, an intermediate layer and a lower layer. These steps are: a) forming first apertures in the upper layer; b) forming an empty cavity in the intermediate layer, which step is referred to as a pre-release step because a central portion of the upper layer lying between the first apertures is pre-released; c) applying what is called a blocking layer to the upper layer, this layer covering the first apertures, the blocking layer and the central portion together forming a suspended microstructure above the empty cavity; d) producing a boundary trench in the suspended microstructure, so as to form, in this microstructure, a movable portion and a fixed portion, the movable portion forming a movable member of the electromechanical device.Type: GrantFiled: November 29, 2017Date of Patent: October 30, 2018Assignee: Commissariat A L'Energie Atomique et aux Energies AlternativesInventors: Vincent Agache, Francois Baleras

Patent number: 7723854Abstract: This assembly of an object and a support is achieved by using solder bumps. At least two wettability areas are made respectively on an object and on a support. Each solder bump ensures electrical contact and mechanical fixing firstly to one of the wettability areas of object and secondly to one of the wettability areas of support. The melting temperature of solder bumps is lower than the melting temperature of each of the wettability areas. Each wettability area of the object forms an angle of 70° to 110° with respect to each wettability area of the support and the object and the support are mutually distant from one another.Type: GrantFiled: May 14, 2007Date of Patent: May 25, 2010Assignee: Commissariat a l'Energie AtomiqueInventors: Christophe Kopp, Francois Baleras, Christophe Martinez
