Organic zero drive load inverters based on pentacene thin film transistors with periodic groove patterned dielectrics are fabricated using nanoimprinting and soft-contact lamination methods. Depletion mode transistor behavior is achieved when the current direction is parallel to groove direction and enhancement mode transistor behavior is achieved when the directions are crossed. An organic inverter is created after connecting two soft-contact laminated transistors. The electrical performance of the drive transistor can be varied and the organic inverter is tunable. This is done by utilizing a PDMS stamp with the source–drain electrode and changing the angle between the current direction and groove direction. The gain and symmetry of the VTC is improved by using an enhancement mode transistor where the source–drain electrode formed by thermal evaporation instead of being a soft contact-laminated device.
