Patent number: 11417827Abstract: A MEMS piezoelectric device includes a monolithic semiconductor body having first and second main surfaces extending parallel to a horizontal plane formed by first and second horizontal axes. A housing cavity is arranged within the monolithic semiconductor body. A membrane is suspended above the housing cavity at the first main surface. A piezoelectric material layer is arranged above a first surface of the membrane with a proof mass coupled to a second surface, opposite to the first surface, along the vertical axis. An electrode arrangement is provided in contact with the piezoelectric material layer. The proof mass causes deformation of the piezoelectric material layer in response to environmental mechanical vibrations. The proof mass is coupled to the membrane by a connection element arranged, in a central position, between the membrane and the proof mass in the direction of the vertical axis.Type: GrantFiled: December 11, 2018Date of Patent: August 16, 2022Assignee: STMicroelectronics S.r.l.Inventors: Maria Fortuna Bevilacqua, Flavio Francesco Villa, Rossana Scaldaferri, Valeria Casuscelli, Andrea Di Matteo, Dino Faralli

Patent number: 8212234Abstract: Nanosized filamentary carbon structures (CNTs) nucleating over a catalyzed surface may be grown in an up-right direction reaching a second surface, spaced from the first surface, without the need of applying any external voltage source bias. The growth process may be inherently self-stopping, upon reaching a significant population of grown CNTs on the second surface. A gap between the two surfaces may be defined for CNT devices being simultaneously fabricated by common integrated circuit integration techniques. The process includes finding that for separation gaps of up to a hundred or more nanometers, a difference between the respective work functions of the materials delimiting the gap space, for example, different metallic materials or a doped semiconductor of different dopant concentration or type, may produce an electric field intensity orienting the growth of nucleated CNTs from the surface of one of the materials toward the surface of the other material.Type: GrantFiled: October 10, 2011Date of Patent: July 3, 2012Assignee: STMicroelectronics S.R.L.Inventors: Danilo Mascolo, Maria Fortuna Bevilacqua

Patent number: 8143086Abstract: Described herein is an optically controlled electrical-switch device which includes a first current-conduction terminal and a second current-conduction terminal, and a carbon nanotube connected between the first and the second current-conduction terminals, the carbon nanotube being designed to be impinged upon by electromagnetic radiation and having an electrical conductivity that can be varied by varying the polarization of the electromagnetic radiation incident thereon. In particular, the carbon nanotube may for example, in given conditions of electrical biasing, present a high electrical conductivity when it is impinged upon by electromagnetic radiation having a given wavelength and a polarization substantially parallel to the axis of the carbon nanotube itself, and a reduced electrical conductivity when it is impinged upon by electromagnetic radiation having a given wavelength and a polarization substantially orthogonal to the axis of the carbon nanotube itself.Type: GrantFiled: April 8, 2011Date of Patent: March 27, 2012Assignee: STMicroelectronics S.r.l.Inventors: Michele Portico Ambrosio, Maria Grazia Maglione, Maria Fortuna Bevilacqua, Luigi Occhipinti, Salvatore Coffa, Salvatore Castorina
