[ Title ] On a Roll: Manufacturing of Electronics on Flexible Substrates

[ Abstract ]

We are working towards the manufacture of large-area arrays of thin film transistors on polymer substrates using roll-to-roll (R2R) processes exclusively. Self-aligned imprint lithography (SAIL) enables to pattern and align submicron sized features on meter-scaled flexible substrates in the R2R environment. SAIL solves the problem of precision interlayer registry on the moving web by encoding all the geometry information required for the entire patterning steps into a monolithic three-dimensional imprint with discrete thickness modulation. The pre-aligned multiple-step mask structure maintains its alignment regardless of subsequent substrate distortion. Challenges are encountered in relate to the novel natures of using flexible substrates and building toolsets for the R2R processing. In this presentation, I will present the methods of the SAIL process, the resulting active matrix (AM) backplanes, the trajectory of SAIL process development, and the remaining issues for production.
