Next Chips: Organic Transistors and Memories and the Applications They Will Enable

Cost is the big issue and here OTFTs hold out the promise of being manufactured using low-cost printing technology, or at least vapor deposition processes that are much less expensive than the optical lithography approaches used for standard CMOS chips and some silicon TFTs. The other important fact about OTFTs is that they can readily be created on flexible substrates, while conventional silicon devices (including most TFTs) tend to crack if flexed. Flexibility is a factor that helps to promote roll-to-roll manufacture, but almost more importantly, is vital if the rollable displays and embedded sensors and RFIDs that are expected to define the age of ubiquitous computing is to become a reality.
