Inkjet printed organic circuits for addressing non-volatile memory

 

The availability of n- and p-channel solution-processed semiconductors enables the fabrication of complementary circuits, which have the advantages of lower power consumption and simpler design compared to unipolar circuits. At Palo Alto Research Center (PARC), organic complementary circuits have been demonstrated by inkjet printing. With all-printed solution processing, we have fabricated peripheral circuits required for addressing passive matrix arrays. A printed decoder is integrated with an array of ferroelectric capacitors for flexible memory applications. The decoder is currently designed to handle 3-bit (8 cells) address lines. In addition to demonstrating the decoder performance, we will also discuss how we tackle the challenges of device variations and stability in printed transistors.
