제목 | Effect of thermal annealing on the properties of polysilicon metal-semiconductor-metal photodetecotrs |
초록 | The effects of the post annealing temperatures on the electrical and interfacial properties of metal-semiconductor-metal photodetectors (MSM-PD) device were investigated. The MSM-PD device in this work were the structure of Al(500 nm)/Ti(200 nm)/poly-Si(500 nm). Structural analyses of the MSM-PD devices were performed by employing X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscope (TEM). Electrical characteristics of the MSM-PD were also carried out by using current-voltage (I-V) measurements. As the post annealing temperature increases, Intermetallic compounds of Al3Ti and Ti7Al5Si12 were observed at interface of the MSM-PD devices at the post annealing temperature of 350℃ and 400℃, respectively, resulting in the decrease in the electrical characteristic. The effects of the post annealing temperatures on the MSM-PD devices showed the different interfacial properties. |
