Publication number: 20230050030Abstract: An electronic device is disclosed that comprises a substrate and an electronic circuit with a layer between them. The layer comprises an electrically insulating medium containing a spatial distribution of conductive elements. The electronic circuit comprises memory contacts arranged for electrical connection to a corresponding contact on the substrate when at least one of the conductive element forms a connection between a memory contact and the corresponding contact but for electrical insulation from the corresponding contact when no conductive elements forms such a connection. A selection of the memory contacts, that is at least partially random, is thus electrically connected to the corresponding contact on the substrate. Memory circuitry is configured to store a representation of a respective electrical connection status of the memory contacts.Type: ApplicationFiled: September 15, 2020Publication date: February 16, 2023Applicant: PRAGMATIC PRINTING LIMITEDInventor: Brian COBB

Patent number: 10020377Abstract: A method of manufacturing an electronic device comprising a first terminal (e.g. a source terminal), a second terminal (e.g. a drain terminal), a semiconductor channel connecting the first and second terminals and a gate terminal to which a potential may be applied to control a conductivity of the channel. The method comprises a first exposure of a photoresist from above the substrate using a mask and a second exposure from below, wherein in the second exposure the first and second terminals shield a part of the photoresist from exposure. An intermediate step reduces the solubility of the photoresist exposed in the first exposure. A window is formed in the photoresist at the location which was shielded by the mask, but exposed to radiation from below. Semiconductor material, dielectric material and conductor material are deposited inside the window to form a semiconductor channel, gate dielectric, and a gate terminal, respectively.Type: GrantFiled: November 7, 2016Date of Patent: July 10, 2018Assignee: Pragmatic Printing LimitedInventors: John James Gregory, Richard David Price
