We fabricated back-channel-cut and back-channel-passivated hydrogenated amorphous silicon (a-Si:H) thin-film transistors (TFTs) on clear-plastic (CP) foil substrates using a silicon nitride (SiN∞) deposition temperature of 300°C. The TFTs were fab

We have fabricated active-matrix organic light emitting diode (AMOLED) test arrays on an optically clear high-temperature flexible plastic substrate at process temperatures as high as 285 degC using amorphous silicon thin-film transistors (a-Si TFTs)

The transition of thin-film transistor (TFT) backplanes from rigid plate glass to flexible substrates requires the development of a generic TFT backplane technology on a clear plastic substrate. To be sufficiently stable under bias stress, amorphous-

We have made hydrogenated amorphous-silicon thin-film transistors (TFTs) at a process temperature of 300degC on free-standing clear-plastic foil substrates. The key to the achievement of flat and smooth samples was to design the mechanical stresses i

The stability of thin-film transistors (TFTs) of hydrogenated amorphous-silicon (a-Si:H) against gate-bias stress is improved by raising the deposition power and temperature of the silicon nitride gate dielectric. We studied the effects of power dens

While crystalline silicon FET's are the key enablers for the integrated circuit field, amorphous silicon thin film transistors are the key semiconductor of the large-area electronics field, also known as “macroelectronics.” This talk reviews the

We report amorphous silicon thin film transistors (a-Si TFT's) with an extrapolated DC saturation current half-life of more than 100 years, an improvement of over 1000 times compared to the previous art (1-4). This TFT half-life is higher than the lu

An important technical issue associated with using a-Si for AMOLED displays is the direct voltage programming of the pixel by providing a constant current source to the OLED. Since only n-channel a-Si TFT's are available, this requires connecting the

The prospect of large-area electronics on polymers, for flexible applications requires a study of thin film fracture mechanisms. To fabricate thin-film transistor (TFT) backplanes on polymer foils the substrate must first be passivated to protect the
