Dual-Function Ladder Polysilsesquioxanes for Precise Patterning and 3D Integration of High-Performance Flexible Organic Logic Circuits

• • Field-effect mobility improved approximately 4-fold compared to conventional SiO2 dielectrics, indicating superior charge transport in C8-BTBT films on LPSQ. • • Voltage gain >100 achieved in flexible inverters, demonstrating high noise margin and suitability for complex logic. • • 4-inch-scale 3D integration of flexible logic circuits (NOR, NAND gates) realized, proving scalability to large-area manufacturing. • • Dual-function LPSQ dielectrics enable both insulation and patterning, eliminating need for photolithography and reducing process complexity.
