Organic thin film transistors based on Weak Epitaxy Growth (WEG) technology are fabricated with two different design: top-gate and bottom-gate configurations. The active layer materials of the OTFT are p-6P and vanadyl phthalocyanine (VOPc). The two structural OTFTs are prepared under the same process conditions
and it is found that the device performance is different. The mobility of top-gate OTFT is much higher than that of the bottom-gate OTFT. A high mobility of 1.6 cm

/V穝 is obtained in the top-gate structure. The differentiation of top-gate and bottom-gate OTFTs is studied by Weak Epitaxy Growth (WEG) technology
and the reasons of higher mobility OTFT based on the top-gate configuration is explained.
