Patent number: 10950489Abstract: Designs for radiation hardening CMOS devices and integrated circuits using shallow trench isolation (STI) improve total ionizing dose (TID) radiation response by reducing the leakage currents from source to drain associated with corners and sidewalls of trench insulator edges passing under the gate in an NMOS device while maintaining high breakdown voltage. A silicide block pattern is used in combination with pullback of N+ source and drain regions from at least a portion of these edges of the active region. Additional p-type implants along these edges further increase parasitic threshold voltages and enhance radiation hardness. A process for fabricating devices and integrated circuits incorporating these features is also provided. These techniques and processes are applied to exemplary low-voltage NMOS transistors having straight gates and to high-voltage annular-gate devices, as well as to device-to-device isolation in integrated circuits.Type: GrantFiled: July 24, 2020Date of Patent: March 16, 2021Assignee: TallannQuest LLCInventor: Emily Ann Donnelly

Patent number: 10242151Abstract: A method, system, and computer program product include electronic design automation (EDA) tools used with standard CMOS processes to design and produce radiation-hardened (rad-hard) integrated circuits (ICs) having a predictable level of radiation hardness while maintaining a desired level of performance and tracking circuit area. The tools include rad-hard design rule checking (DRC) decks, rad-hard SPICE models, and rad-hard cell libraries. A rad-hard parasitic components extraction process makes use of rad-hard DRC rules to locate occurrences of parasitic devices, calculate their effects on circuit performance, and return this information to layout and circuit simulation tools. Changes to the layout are suggested and implemented with varying degrees of automation. Some of these tools can be provided as components of a rad-hard process design kit (PDK). They can be used in conjunction with commercial EDA tools to facilitate the incorporation of rad-hard features into new or existing IC designs.Type: GrantFiled: August 31, 2017Date of Patent: March 26, 2019Assignee: TallannQuest LLCInventor: Emily Ann Donnelly
