20080224242 | PROCESS FOR MANUFACTURING A MEMBRANE OF SEMICONDUCTOR MATERIAL INTEGRATED IN, AND ELECTRICALLY INSULATED FROM, A SUBSTRATE - A process for manufacturing an integrated membrane made of semiconductor material includes the step of forming, in a monolithic body of semiconductor material having a front face, a buried cavity, extending at a distance from the front face and delimiting with the front face a surface region of the monolithic body, the surface region forming a membrane that is suspended above the buried cavity. The process further envisages the step of forming an insulation structure in a surface portion of the monolithic body to electrically insulate the membrane from the monolithic body; and the further and distinct step of setting the insulation structure at a distance from the membrane so that it will be positioned outside the membrane at a non-zero distance of separation. | 09-18-2008 |
20080315333 | SUBSTRATE-LEVEL ASSEMBLY FOR AN INTEGRATED DEVICE, MANUFACTURING PROCESS THEREOF AND RELATED INTEGRATED DEVICE - A substrate-level assembly having a device substrate of semiconductor material with a top face and housing a first integrated device, including a buried cavity formed within the device substrate, and with a membrane suspended over the buried cavity in the proximity of the top face. A capping substrate is coupled to the device substrate above the top face so as to cover the first integrated device in such a manner that a first empty space is provided above the membrane. Electrical-contact elements electrically connect the integrated device with the outside of the substrate-level assembly. In one embodiment, the device substrate integrates at least a further integrated device provided with a respective membrane, and a further empty space, fluidically isolated from the first empty space, is provided over the respective membrane of the further integrated device. | 12-25-2008 |
