用于太赫兹成像的CMOS肖特基二极管三维结构研究
Three-dimensional structure analysis of Schottky barrier diode in CMOS technology for terahertz imaging
摘要
Abstract
A simple and effective design method for high cut-off frequency Schottky barrier diode is proposed andimplemented. The cut-off frequency of the processed Schottky barrier diode is about 800 GHz,which can reach about 1 THz with the optimized parameters through the test results and simulation data in SMIC 180 nm process. The integrated detector including antennas,matching circuit and Schottky barrier diode is completed,whose test-ed responsivity could achieve 130 V/W and noise equivalent power is estimated to be 400 pW/ Hz at 220 GHz. The imaging experiment of invisible liquid surface in ceramic bottles has been completed and good results have been achieved.关键词
