Review: A fully-additive printed electronics process with very-low process variations (Bent and unbent substrates) and PDK

Despite the huge market potential of Printed Electronics on Flexible substrates, the printed circuits and systems are yet to be manufacturable due to high cost fabrication processes, large process variations between devices, large and somewhat intractable variations when the devices and their substrates are bent, and lack of a comprehensive Process Development Kit (PDK). In this review paper, we review our Low-Cost Fully-Additive printing process with these four shortcomings addressed. To the best of our knowledge, this process is arguably the Fully-Additive printing process that is closest to being manufacturable and for the realization of practical intelligent printed electronics.
