We reported on a two-dimensional simulation of electrical properties of the radio frequency ͑rf͒ sputter amorphous In–Ga–Zn–O ͑a-IGZO͒ thin-film transistors ͑TFTs͒. The a-IGZO TFT used in this work has the following performance: field-effect mobility ͑␮ eff ͒ of ϳ12 cm 2 / V s, threshold voltage ͑V th ͒ of ϳ1.15 V, subthreshold swing ͑S͒ of ϳ0.13 V / dec,(More)
|This paper presents a detailed study on the impact of oating body in partially-depleted (PD) SOI MOS-FET on various digital VLSI CMOS circuit families. The parasitic bipolar eect resulting from the oating body is shown to degrade the circuit noise margin and stability i n general. In certain dynamic circuits and wide multiplex-ers, the parasitic bipolar(More)
W (AM) flat panel displays (F F e studied the optical and electrical properties of the amorphous indium gallium zinc oxide thin-film transistors (a-IGZO TFTs). To develop a-IGZO density-of-states model, intrinsic a-IGZO optical properties such as optical band gap and Urbach energy, and TFT characteristics under illumination are investigated. During the(More)
