Characteristics of Polycrystalline Silicon TFT with Stress-Bias

스트레스에 따른 다결정 실리콘 TFT의 영향

Polycrystalline Silicon Thin Film Transistors(Poly-Si TFT's), fabricated at temperature lower than $600^{\circ}C$ are now largely used in many applications, particularly in large area electrons. In this work, electrical stress effects on Poly-Si TFT's fabricated by Solid Phase Crystal(SPC) was investigated by measuring electric properities such as transfer and output characteristics, and channel conductance. Consequently, It is turned out that it should be noted the output characteristics, drain current and channel conductance, strongly degrade around origin.
