A monolithic manufacturing process is presented for the realization of active-matrix meshed thin-film-transistor (TFT) arrays on foil with physical voids between pixels, realizing membrane-like electronic arrays. The process is scalable to large-area substrates and enables (improved performance of) biometrics-under-display applications. Moreover...

Sub-micrometer thin-film transistors (TFTs) are realized using multi-level imprint lithography. Amorphous indium gallium zinc oxide (α-IGZO) TFTs with channel lengths as small as 0.7 μm, field-effect mobility of 10 cm2 V−1 s−1 and on/off ratio of circa 107 were integrated into a 1000-pixels per inch (ppi) TFT backplane array. The reduction of...

This paper presents a new compensation principle using a 2T1C pixel circuit. The implementation shows significant improvement in uniformity for all grey-levels, due to compensation for both VT and β-factor variations. The resulting current variation after compensation in the characterized display area reaches values down to 0.079%.

In this work, we demonstrate a capacitive coupled data transfer with flexible thin-film electronics using touchscreen as ubiquitous reader interface. The capacitive communication to the touchscreen is proven using a 64-bit metal-oxide thin-film capacitive-coupled identification tag. The tag is powered by a thin film battery or thin-film...

The thin-film-transistor (TFT) technology has attracted significant attention in account of the possibility to manufacture transistors on large and flexible substrates, at low processing temperatures and at a low cost. Next to the well-established amorphous silicon TFT technology used mostly for displays, the amorphous Indium-Gallium-Zinc-Oxide ...

A unique vertical organic field-effect transistor structure in which highly doped silicon nanopillars are utilized as a gate electrode is demonstrated. An additional dielectric layer, partly covering the source, suppresses bulk conduction and lowers the OFF current. Using a semiconducting polymer as active channel material, short-channel (100 nm...

Capacitive touchscreens are increasingly widespread, featuring in mobile phones and tablets, as well as everyday objects such as cars and home appliances. As a result, the interfaces are uniquely placed to provide a means of communication in the era of the Internet of Everything. Here, we show that commercial touchscreens can be used as reader...

Thin-film transistors (TFTs) are the fundamental building blocks of today's display industry. To achieve higher drive currents and device density, it is essential to scale down the channel lengths of TFTs. To be able to fabricate short-channel TFTs in large volumes is also equally important in order to realize lower fabrication costs and higher...

Indium gallium zinc oxide (IGZO) is deposited using plasma‐enhanced spatial atomic layer deposition (sALD) on substrates as large as 32 × 35 cm2. Excellent uniformity and thickness control leads to high‐performing and stable coplanar top‐gate self‐aligned (SA) thin‐film transistors (TFTs). The integration of a sALD‐deposited aluminum oxide...
