抄録: | Solution processes for electronic devices, instead of conventional vacuum process and vapour deposition, have been receiving considerable attention for a wide range of applications such as electroluminescent displays^<1, 2>, solar cells^3, ferroelectric films^4, transparent conductive films^5, SiO_2 films^6 and metal films^7, to reduce the processing cost. In particular, printing semiconductor devices using liquid materials is considered to be important for new applications, such as large-area flexible displays. Recent research has been focused on organic semiconductors^<8-11>, which have mobilities comparable to that of amorphous silicon (α-Si)^11, but are insufficiently reliable. Solution processing of metal chalcogenide semiconductors to fabricate stable and high-performance transistors has also been reported^<12, 13>. This class of materials is targeted as substitutions for the silicon devices that requiree complex and expensive manufacturing processes. However, if high-quality silicon film could be prepared by solution process, this situation would change drastically. Here we demonstrate the solution process of silicon thin film transistors (TFTs) using a novel liquid precursor. We have formed poly-crystalline silicon (poly-Si) films by spin-coating or by ink-jetting the precursor to fabricate TFTs that operated with a mobilities of 108 cm^2V^<-1>s^<-1> and 6.5 cm^2V^<-1>s^<-1>, respectively. These values cannot be achieved by solution-processed organic TFTs or α-Si TFTs, whose mobility is 1 cm^2V^<-1>s^<-1> at most. |
