5. Contents
In this talk I will review the critical path issues xembedded in direct fabrication (as opposed to layer transfer) of amorphous silicon (a-Si:H) transistor arrays on flexible substrates include low temperature a-Si:H process development and transition to plastic and metal foil substrates. We have developed a low temperature channel-passivated a-Si:H TFT process on a professionally-staffed 6’’ water-scale Pilot Line. The process was designed to be high yielding and to be readily scaled to display manufacturing toolsets. The transistor design is a standard bottom-gate inverted staggered tri-layer TFT architecture.
