Flexible
electronics: Distributed large area (cm2-to-m2) electronic systems based on
flexible thin-film-transistor (TFT) technology are drawing much attention due
to unique properties such as mechanical conformability, low temperature process
ability, large area coverage, and low fabrication costs. Various forms of
flexible TFTs can either enable applications that were not achievable using
traditional silicon based technology, or surpass them in terms of cost per
area. Flexible electronics cannot match the performance of silicon-based ICs
due to the low carrier mobility. Instead, this technology is meant to
complement them by enabling distributed sensor systems over a large area with
moderate performance (less than 1 MHz). Development of inkjet or roll-to-roll
printing techniques for flexible TFTs is underway for low-cost manufacturing,
making product-level implementations feasible. Despite these encouraging new
developments, the low mobility and high sensitivity to processing parameters
present major fabrication challenges for realizing flexible electronic systems

CMOS scaling is
coming to an end, but no single technology has emerged as a clear successor to
silicon. The urgent need for post-CMOS alternatives will continue to drive
high-risk, high-payoff research on novel device technologies. Replicating
silicon’s success might sound like a pipe dream. But with the world’s best and
brightest minds at work, we have reasons to be optimistic.
