Patent number: 11962616Abstract: A method and associated circuits protect data stored in a secure data circuit of a telecommunication device equipped with a near-field communication (NFC) router, a microcontroller, and the secure data circuit. In the method, each message received with the NFC router is parsed to retrieve a communication pipe identifier and an instruction code. The communication pipe identifier and the instruction code are compared to corresponding information in a filter table. Instruction codes of particular messages that attempt to modify a communication pipe by reassigning one end of the communication pipe from the port of the NFC router to a different circuit are acted upon. These messages are blocked from reaching the secure data circuit when the instruction code is not authorized in the filter table, and these messages are permitted when the instruction code is authorized in the filter table.Type: GrantFiled: January 11, 2021Date of Patent: April 16, 2024Assignees: PROTON WORLD INTERNATIONAL N.V., STMICROELECTRONICS (ROUSSET) SASInventors: Olivier Van Nieuwenhuyze, Thierry Huque, Alexandre Charles

Patent number: 11948977Abstract: Transistors having partially recessed gates are constructed on silicon-on-insulator (SOI) semiconductor wafers provided with a buried oxide layer (BOX), for example, FD-SOI and UTBB devices. An epitaxially grown channel region relaxes constraints on the design of doped source and drain profiles. Formation of a partially recessed gate and raised epitaxial source and drain regions allow further improvements in transistor performance and reduction of short channel effects such as drain induced barrier lowering (DIBL) and control of a characteristic subthreshold slope. Gate recess can be varied to place the channel at different depths relative to the dopant profile, assisted by advanced process control. The partially recessed gate has an associated high-k gate dielectric that is initially formed in contact with three sides of the gate. Subsequent removal of the high-k sidewalls and substitution of a lower-k silicon nitride encapsulant lowers capacitance between the gate and the source and drain regions.Type: GrantFiled: June 28, 2022Date of Patent: April 2, 2024Assignee: STMICROELECTRONICS, INC.Inventor: John H.
