Abstract(in English) | We fabricated a polycrystalline silicon (poly-Si) photoconductor and measured a sensitivity and frequency characteristics at a wavelength of 650 nm. Poly-Si layers are obtained by thermal annealing of amorphous silicon (a-Si). The a-Si is heated in a nitrogen atmosphere at 600℃, 100 min. The a-Si is deposited by the catalytic chemical vapor deposition (Cat-CVD). The electrodes are patterned by the photolithography and the liftoff process. The electrodes pattern is formed by comb structure, the receiving area of 50×50 μm^2 and the electrode width of 2 pm. The sensitivity of 36 mA/W and the maximum bandwidth of 30 MHz were obtained at the wavelength of 650 nm and the bias voltage of 30 V. The 0.2 μm thick of poly-Si film is obtained by dry etching method of 1.2 μm poly-Si. We measured the optical characteristics of 0.2 pm thick poly-Si photoconductor is also measured. The sensitivity of 0.8 mA/W and the maximum bandwidth of 200 MHz were obtained at the wavelength of 650 nm and the bias voltage of 30 V. |
