Integrated circuit comprising a single photon avalanche diode and corresponding manufacturing method
Patent number: 11949035Abstract: A single photon avalanche diode (SPAD) includes a PN junction in a semiconductor well doped with a first type of dopant. The PN junction is formed between a first region doped with the first type of dopant and a second region doped with a second type of dopant opposite to the first type of dopant. The first doped region is shaped so as to incorporate local variations in concentration of dopants that are configured, in response to a voltage between the second doped region and the semiconductor well that is greater than or equal to a level of a breakdown voltage of the PN junction, to generate a monotonic variation in the electrostatic potential between the first doped region and the semiconductor well.Type: GrantFiled: December 9, 2021Date of Patent: April 2, 2024Assignees: STMicroelectronics (Crolles 2) SAS, STMicroelectronics (Research & Development) LimitedInventors: Denis Rideau, Dominique Golanski, Alexandre Lopez, Gabriel Mugny -
Patent number: 11921815Abstract: A server system can receive an input identifying a problem to generate a solution using a machine-learning application. The method selects a machine-learning model template from a plurality of templates based at least in part on the input. The method analyzes one or more formats of the customer data to generate a customer data schema based at least in part a data ontology that applies to the identified problem. The method determines whether the customer data schema is misaligned with one or more key features of the selected machine-learning model template. Based on this determination, the method analyzes the metadata for the selected machine-learning model template to determine what additional information is required to re-align the customer data with the data expectations. The method can include gathering the addition information required to re-align the customer data with the data expectations of the selected machine-learning model template.Type: GrantFiled: September 13, 2020Date of Patent: March 5, 2024Assignee: Oracle International CorporationInventors: Alberto Polleri, Sergio Aldea Lopez, Marc Michiel Bron, Dan David Golding, Alexander Ioannides, Maria del Rosario Mestre, Hugo Alexandre Pereira Monteiro, Oleg Gennadievich Shevelev, Larissa Cristina Dos Santos Romualdo Suzuki, Xiaoxue Zhao, Matthew Charles Rowe
