Abstract: Flexible transistors and electronic circuits incorporating the transistors are provided. The flexible transistors promote heat dissipation from the active regions of the transistors while preserving their mechanical flexibility and high-frequency performance. The transistor designs utilize thru-substrate vias (TSVs) beneath the active regions of thin-film type transistors on thin flexible substrates. To promote rapid heat dissipation, the TSVs are coated with a material having a high thermal conductivity that transfers heat from the active region of the transistor to a large-area ground.

Abstract: Stretchable high frequency transmission lines and high-frequency filters comprising the transmission lines are provided. The transmission lines provide low power loss, even at microwave and millimeter wave frequencies. The transmission lines are thin and flexible and can be stretched without a significant degradation of their scattering parameters. As a result, the transmission lines have applications as interconnects in stretchable and flexible integrated circuits (IC) and circuit device components, such as flexible transistors and flexible diodes.
