Abstract:Polysilicon complementary metal oxide semiconductor (CMOS) thin film transistors (TFTs) are fabricated on large area, flexible stainless steel foils using novel ink depositions within a hybrid printed/conventional process flow. A self-aligned top gate TFT structure is realized with an additive materials approach to substitute the use of high capital cost ion implantation and lithography processes. Polyhydrosilane-based silicon ink is coated and laser crystallized to form the polysilicon channel. Semiconductor … Show more
