摘要
设计了与标准CMOS工艺兼容的硅双光电探测器,并从理论上计算和分析了其绝对光谱响应。0.5pmCMOS工艺条件数值模拟结果显示,在无抗反射膜情况下该探测器在400~900nm波长范围内响应度都在0.2A/W以上,尤其是在短波长处效果比一般的探测器要好。还就反向偏压以及CMOS工艺中介质与钝化层等因素对探测器响应度的影响进行了讨论。
A CMOS-process-compatible silicon double photodetector is designed. And the theoretical absolute spectral response of this photodetector is calculated and analyzed. The spectral responsivity in 0. 5 μm CMOS process is simulated. Simulation results show better spectral responsivities especially in the short wavelength range. The responsivity is above 0.2 A/ W within the wavelength range from 400 nm to 900 nm without anti-reflection-coating. The responsivity dependent on the insulated medium and passivation layers in CMOS process and reverse bias is also discussed.
