Abstract:

The research process of the technology of total dose radiation hardening is analyzed. Integrated circuit technology innovation in materials, device structure, layout design and system structure, promotes the development of the total dose reinforcement technology. The new technology increases the capability of total dose reinforcement and extends the life of the electronic systems in the radiation environment. The recently proposed new total dose radiation hardening technologies, such as using new material like Ag-Ge-S, Single-Wall Carbon Nanotube(SWCNT) etc., adopting Drain/Source On Insulator (DSOI) device structure, OCTOgonal-gate(OCTO) layout, Alternate Biasing Triple Modular Redundancy (ABTMR) system structure, are summarized. These technologies increase the resistance capability to total dose radiation of devices and electronic systems significantly. The research results will help to establish a complete total dose reinforcement system to enhance the anti-radiation index, and can provide reference for promoting the rapid development of total dose radiation hardening technology.
