Abstract

original image

On page 5224, W. H. Lee, K. Cho, and co-workers demonstrate an inkjet printing process for the fabrication of TIPS-PEN crystals in microwells. First, the inkjet printing solvent produces the microwells by dissolving a polymer layer on an electrode-patterned gate dielectric layer (left lane in the image). Next, TIPS-PEN crystals are fabricated by inkjet printing TIPS-PEN ink into the inkjet-etched microwells (central lane). The final morphology of the transistors with TIPS-PEN crystals is shown in the right lane.
