Publication number: 20240184050Abstract: A photonic motor has at least one optical radiation input, a first optical waveguide arrangement having at least one first optical resonator lying in a first region of space of a common plane, an excitation optical waveguide arrangement, and a second optical waveguide arrangement having at least one second optical resonator lying in a second region of space of the common plane and configured to move in the second region of space. The first and second optical resonators drive a fundamental symmetric resonant mode and a fundamental anti-symmetric resonant mode. When the fundamental symmetric mode is established, an attractive condition generates a motion of approach of the second optical resonator towards the first optical resonator. When the fundamental anti-symmetric resonant mode is established, a repulsion condition generates a motion of departure of the second optical resonator from the first optical resonator.Type: ApplicationFiled: March 23, 2022Publication date: June 6, 2024Inventors: Carlo Edoardo CAMPANELLA, Giovanni DE AMICIS, Alfonso D'ANNA

Patent number: 11127776Abstract: A method to perform hybrid bonding of two semiconductor wafers without using a dedicated tool for thermo-compression is disclosed. According to the herein disclosed technique, the semiconductor wafers to be bonded together may be placed in an oven simply staying one upon the other without applying any additional compression between them besides their own weight. This outstanding result has been attained using of a particular type of thermosetting materials, namely siloxane polymers of the type that shrink when cured. Among these siloxane polymers, the siloxane polymers of the type SC-480, siloxane polymers of the series SC-200, SC-300, SC-400, SC-500, SC-700, SC-800 and mixtures thereof are particularly suitable.Type: GrantFiled: May 17, 2018Date of Patent: September 21, 2021Assignee: LFOUNDRY S.R.L.Inventors: Giovanni De Amicis, Andrea Del Monte, Onorato Di Cola

Publication number: 20180192876Abstract: An optical sensor based on CMOS technology including a semiconductor substrate; an array of photocells, each of which includes a respective photodetector active area that is formed in and exposed on a given planar surface of said semiconductor substrate; a multilayer structure that includes metal and dielectric layers and is formed on the given planar surface; and light shielding means formed in or on the multilayer structure; wherein each photodetector active area is associated with a corresponding optical path extending through the light shielding means and directed towards said photodetector active area. All the photocells are connected in parallel to provide an overall output electrical signal related to incident light impinging on the photodetector active areas. All the optical paths are parallel to a given direction thereby causing all the photodetector active areas to be reached by incident light with incident direction parallel to said given direction.Type: ApplicationFiled: July 7, 2016Publication date: July 12, 2018Inventors: Fabio Spaziani, Andrea Del Monte, Giovanni Margutti, Giovanni De Amicis

Patent number: 9595555Abstract: An image sensor may include isolation regions that are formed in between photodiodes. These isolation regions may prevent cross-talk and improve the performance of the image sensor. The isolation regions may include a conductive layer that is electrically connected to a bias voltage supply line. Biasing the conductive layer may result in a charge inversion in the substrate adjacent to the conductive layer. The charge inversion may prevent the generation of dark current. The conductive layer may be formed on a liner oxide layer in trenches formed in epitaxial silicon. A connecting layer may be used to electrically connect each conductive layer. The connecting layer may be formed integrally with the conductive layer or formed from a separate material.Type: GrantFiled: May 4, 2015Date of Patent: March 14, 2017Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Daniel Tekleab, Giovanni De Amicis

Publication number: 20170017534Abstract: The present invention relates to a method and apparatus which corrects antenna noise temperature in antenna back lobes, for earth-observing microwave instruments on satellites in orbit, to counter signal contamination from celestial bodies. The antenna back lobe signal correction is computer-program-modeled with only a few static and only a few dynamic inputs, and for a given set of parameters (i.e., orbital altitude, pointing characteristics (e.g., nadir or cross-scanning or conical-scanning), frequency selectivity of the receiver/detector) produces a few output files which are then combined by the program to predict the back lobe signal correction which is to be applied.Type: ApplicationFiled: July 16, 2015Publication date: January 19, 2017Inventor: Giovanni De Amici

Publication number: 20130009269Abstract: An imaging system may include an imager integrated circuit with frontside components such as imaging pixels and backside components. The imager integrated circuit may also include mirrored alignment marks formed with the frontside components. As part of forming the backside components, the integrated circuit may be flipped over such that the mirrored alignment marks are no longer mirrored and are readable by alignment systems. The formerly mirrored alignment marks may be used by the alignment systems in aligning the backside components with the frontside components in the imager integrated circuit (e.g., in forming the backside components in alignment with the frontside components).Type: ApplicationFiled: December 2, 2011Publication date: January 10, 2013Inventors: Gianluca Testa, Giovanni De Amicis

Publication number: 20130001728Abstract: Methods for forming backside illuminated (BSI) image sensors having vertical light shields are provided. Vertical light shields may be configured such that incoming light is blocked from reaching a portion of a pixel array formed on the backside illuminated image sensor. Vertical light shields may include horizontal portions that block direct illumination of dark pixels in the pixel array and vertical portions that block illumination of the dark pixels by reflected light. Vertical light shields may be formed from a dielectric layer, a layer of patterned light shield material formed over the dielectric layer and a passivation layer formed over the patterned light shield material. Vertical light shields may be formed by first etching a vertical trench in a device wafer layer over a portion of the pixel array and filling the vertical trench with light shield material to form the vertical light shield.Type: ApplicationFiled: July 25, 2011Publication date: January 3, 2013Inventor: Giovanni De Amicis

Publication number: 20080290436Abstract: A photon guiding structure for reducing optical crosstalk in an image sensor and method of forming the same. The method includes forming a trench within an interlayer dielectric region formed over a photo-conversion device. The trench is formed such that it is vertically aligned with and has a horizontal cross-sectional shape similar to that of the photo-conversion device. A material is formed within the trench and a dielectric is formed over the material. The lined trench causes photons to strike the proper photo-conversion device and, as such, reduces the chance that photons will impinge upon neighboring photo-conversion devices.Type: ApplicationFiled: October 10, 2007Publication date: November 27, 2008Inventor: Giovanni De Amicis
