Molecular electronic devices that utilize molecules as electronic device components are fascinating [1], however molecular devices are not so practical because a typical vertically structured molecular devices has a very low devices yield. In this talk, I will explain a few methods to overcome this low yield problem; for example, (1) a method by introducing an intermediated protective layer between the molecular layer and the top electrode [2], and (2) a method with a direct metal transfer technique [3]. I will further explain our recent demonstration of molecular devices with device functionalities such as rectifying or photoswitching on flexible substrates [4].
