摘要
研究了基于0.5 μm 互补金属氧化物半导体(CMOS)工艺的动态阈值MOS(DTMOS)晶体管的电流-电压特性曲线。与常规CMOS 工艺PNP 晶体管特性对比,得到了带隙电压基准电路设计准则;采用DTMOS 和抗辐射设计加固技术,完成了抗辐射加固CMOS 基准设计。辐照试验结果表明,设计的抗辐射加固CMOS 基准的抗总剂量能力达到了300 krad(Si)。
Abstract
The I -U characteristic curves of Dynamic Threshold MOS(DTMOS) transistor are obtained based on 0.5 μm Complementary Metal Oxide Semiconductor(CMOS) process. Compared with the PNP transistor of conventional CMOS technology, the design criteria are given, which are used to design the radiation-hardened CMOS reference. The radiation-hardened CMOS reference is completed by using DTMOS diodes as radiation tolerance diodes and combining the Radiation Hardening By Design(RHBD) technology. The experimental results show that the ability of anti-γ ionizing radiation total dose reaches up to 300 krad(Si) for the radiation-hardened CMOS reference.
