Publication number: 20230375680Abstract: This disclosure relates to a time-of-flight sensor including, on a same base substrate, a light emitter configured to emit light into an image scene, a reference sensor configured to detect light emitted by the light emitter, and a signal reception sensor array separated from the light emitter by an optical barrier. The optical barrier is configured to prevent light emitted by the light emitter from directly reaching the signal reception sensor array, with the signal reception sensor array being configured to detect light reflected by the image scene. The reference sensor and the signal reception sensor array are based on semiconductor nanoparticles.Type: ApplicationFiled: May 10, 2023Publication date: November 23, 2023Applicants: STMicroelectronics (Research & Development) Limited, STMicroelectronics (Grenoble 2) SASInventors: Neale DUTTON, Jonathan STECKEL

Publication number: 20230317748Abstract: An imaging device includes an array of photosensors. A film of semiconductor nanoparticles is common to the photosensors of the array. The nanoparticles are configured to be excited by light with wavelengths in a range from 280 to 1500 nanometers. Each photosensor includes a top electrode and a bottom electrode positioned on opposite sides of the film of semiconductor nanoparticles. At least some of the photosensors further include a filter configured to transmit light with wavelengths in a range from 280 to 400 nanometers, and to at least partially filter out light with wavelengths greater than 400 nanometers from reaching the photosensor. A transistor level is electrically coupled to the top and bottom electrodes of the photosensors.Type: ApplicationFiled: April 3, 2023Publication date: October 5, 2023Applicants: STMicroelectronics (Grenoble 2) SAS, STMicroelectronics (Crolles 2) SAS, STMicroelectronics (Alps) SASInventors: Jonathan STECKEL, Emmanuel JOSSE, Eric MAZALEYRAT, Youness RADID
