Laser patterned junctionless neuron thin-films transistor arrays
Indium-zinc-oxide (IZO) thin film transistors (TFT) have been fabricated on ITO/glass substrate with a laser scribing process at room temperature. Such transistors are composed of a bottom indium-tin-oxide (ITO) floating gate and multiples of in-plane control gates. The multiple input gates are not truly independent gates, capacitively coupling with the floating gate together, thus Neuron MOS (vMOS) operation is realized. The control gates, coupling with the floating gate, control the “on” and “off” of the neuron transistor. Robust AND logic is demonstrated on such neuron transistor.
