제목 The effect of functional groups of dielectric surface on the IGZO-based thin film transistors
초록 Metal oxide semiconductors have several advantages such as transparency, high transistor performance and air stability over amorphous silicon and organic semiconductors. In-Ga-Zn-O system (IGZO) semiconductor is one of the metal oxide and also has high electron conductivity. In this study, a change of characteristics of the IGZO-based TFT is examined according to the different dielectric functional groups. Our team chooses silicon oxide and polymer bilayer dielectric system to change dielectric surface. We use polymers having different functional groups, poly(4-vinylpyridine)(PVP) which is electron donating group, poly styrene(PS) and poly(4-vinylphenol)(PHS) which is electron withdrawing group.
