Low-Voltage Thin Film Transistors
Flexible, wearable electronic devices will offer new opportunities for improved connectivity, smart objects and healthcare. The fulfilment of such devices is contingent upon reducing the power consumption of the electronics so that the device is easily powered by a battery. However, reducing the power consumption of thin-film transistors – one of the fundamental components of flexible electronics – while maintaining high yields and low costs has proven difficult.
A research team at the University of Manchester has developed a method to produce such low voltage semiconductors using a solid-state electrolyte dielectric. The high capacitance of the dielectric – a result of ionic conduction – allows for low voltage device operation. While other techniques reduce the dielectric thickness to achieve high capacitance – sacrificing the quality of the insulating behaviour – the ionic conduction in the solid-state electrolyte enables thick dielectric layers to maintain high capacitance and thus low voltage operation.
The invention is a method for manufacturing Thin Film Transistors operating at less than 1V. This technology offers a means of producing low voltage devices at reduced cost and improved yield using existing processes and will find application in several fields, including displays, sensors and wearables.
