Organic half-wave rectifier fabricated by stencil lithography on flexible substrate
We demonstrate the feasibility of fabrication method combining classic and stencil lithography for producing simple organic rectifying circuits for use in radio frequency range. Two stencil lithography steps are crucial because pentacene, once deposited on the wafer, cannot survive classic lithography resist removal. The presented rectifier is made of one organic Schottky diode followed by a MIM (MetalInsulatorMetal) capacitor, integrated on the same flexible substrate. The devices are fabricated on a flexible polyimide foil by two aligned levels of stencil lithography using ALD deposited high-k hafnium-oxide, (HfO2  experimental ??19).
