Abstract
We have studied the selective coating on the TFT region by spin-casting of 6,13-bis(4-pentylphenylethynyl) pentacene (PPE pentacene). The island of PPE pentacene was formed inside of the banks for TFT, which was independent of self-assembled monolayer layer on source/drain electrodes. A bottom contact TFT with the PPE pentacene using selective coating on TFT region, exhibited the field-effect mobility of 0.02 cm2/V s, an on/off current ratio of 107 and gate voltage swing of 0.8 V/dec. An inverter made of PPE pentacene TFTs was demonstrated to have the signal gain of >1.5 (VDD = −40 V) using selective coating.
