Organic thin-film transistors (OTFTs) with tailored liquid sources of HfO2 as a high-$\kappa$ insulator were investigated. To investigate the effect of UV irradiation, two types of light source were tested. The contact angles of water and polycrystalline condition of a pentacene were systematically changed and the resultant OTFT characteristics were also changed. The field-effect mobilities and on–off ratios obtained using a high-pressure mercury lamp and a deep-UV lamp as irradiation sources were 0.035 and 0.10 cm2 V-1 s-1, and 24 and $3 \times 10^{3}$, respectively.
