    摘要:

    基于Dyakonov和Shur等离子体波振荡原理设计并流片制备了一种采用65 nm 标准CMOS工艺的3.0 THz探测器,探测器包括贴片天线、NMOS场效应晶体管、匹配网络及陷波滤波器。探测器在室温条件下可达到526 V/W的响应率(Rv)和73 pW/Hz1/2的噪声等效功率(NEP)。采用该探测器和步进电机搭建了太赫兹扫描成像系统,获得了太赫兹源出射光斑的远场形状,光斑的半高宽(FWHM)为240;并对聚甲醛牙签和树叶进行了扫描成像实验,结果表明CMOS太赫兹探测器在成像领域有潜在的应用前景。

    Abstract:

    A 3.0 THz detector based on plasma-wave theory proposed by Dyakonov and Shur was designed and fabricated in 65 nm standard CMOS process, the detector consists of a patch antenna, a NMOS field effect transistor, a matching network, and a notch filter, it can achieve a room-temperature responsivity (Rv) of 526 V/W and a noise equivalent power (NEP) of 73 pW/Hz1/2. The terahertz scanning imaging system was built with the detector and stepper motor, and the far-field shape of the terahertz source beam was obtained, the full width at half maximum (FWHM) of the beam is 240 μm; and the image of the polyformaldehyde toothpick and tree leaf were obtained through the scanning imaging system, it shows that CMOS terahertz detectors have potential applications in the imaging field.
