Abstract

In this study, we fabricated of pentacene organic thin film trasistor(OTFT), which used aluminum oxide for the gate insulator on glass substrate. Aluminum oxide for OTFTs was deposited on the gate layer by E-beam evaporation. aluminum oxide fabricated various deposition rate. In this case of the deposition rate of $0.1\;{\AA}$, the fabricated aluminum oxide gate insulator OTFT showed a threshold voltage of -1.36V, an on/off current ratio of $1.9{\times}l0^3$ and field effect mobility $0.023\;cm^2/V_s$.
