Drastic efforts have been realized these last years in order to develop complementary organic technology. This is the essential key to produce elementary low-cost circuits for digital and analog applications. Different techniques [1–3] are available nowadays to obtain both N- and/or P-type organic devices. Screen printing is one of the most highly awaited low-cost techniques that can be used to produce organic devices and circuits. It has been widely used in P-type organic technologies [4, 5]. Now that N-type semiconductors have become much more easily processed, developers are seeking a complete CMOS and lifetime robust technology. Many previous works have reported on a complete solution based on CMOS technology [6–8]. Large-area-compatible organic processes have also been demonstrated [9]. Nevertheless some of the technological steps in these latter reports are not fully printed and/or still present some lithography/vacuum deposition steps. We present here a complete fully printed CMOS technology on flexible substrates showing acceptable device performances and digital/analog circuit functionalities, which can lead to more complex designs.
