The inkjet system is expected to be applied to the manufacture of electronic devices since it is possible to land highly functional materials as individual dots. JAPERA has developed the whole printing base technology of Flexible TFT array. Here, the inkjet method is applied to an organic semiconductor and an interlayer connection electrode which are an isolated dot patterns. By depositing multiple drops of functional material with high precision, we show cases of homogeneously forming thin film semiconductors on electrodes and cases of forming electrode posts of high aspect ratio.
