Thin film transistor fabrication (TFT) is currently lacking a fully verified, universal design approach. This increases the cost and complexity of manufacturing TFT-based flexible electronics, slowing down their integration into more mature applications and limiting the design complexity achievable by foundries. Researchers in Belgium developed a stable and high-yield TFT platform for the fabless manufacturing of two mainstream TFT technologies, wafer-based amorphous indium–gallium–zinc oxide and panel-based low-temperature polycrystalline silicon, two key TFT technologies applicable to flexible substrates. They designed the 6502 microprocessor in both technologies to demonstrate and expand the multi-project wafer approach. Enabling the foundry model for TFT could accelerate the growth and development of applications and technologies based on these devices… read more. Open Access TECHNICAL ARTICLE
