Organic thin-film transistors : from technologies to circuits

Organic molecules (i.e. carbon-based) have opened a new and rapidly-growing industrial field in the optoelectronic market bringing to this field a new dimension of thinness and flexibility. In this context, this thesis has focused on one particular buildin ...

Submicrometer Organic Thin-Film Transistors: Technology Assessment Through Noise Margin Analysis of Inverters

Christian Enz, Jean-Michel Sallese, Rolando Ferrini, Frédéric Zanella, Nenad Marjanovic

In this paper, we propose a methodology to evaluate the potential of submicrometer organic thin-film transistors (OTFTs) with nanoimprinted gate and self-aligned source and drain contacts. In the first step, the dedicated static model we previously reporte ...

Optical-stack optimization for improved SPAD photon detection efficiency

Edoardo Charbon, Claudio Bruschini, Rolando Ferrini, Arin Can Ülkü, Ivan Michel Antolovic, Scott Anthony Lindner, Ekin Kizilkan, Frédéric Zanella

Single-photon avalanche diodes (SPADs) are direct photon-to-digital detectors that enable scalable arrays with Poisson-limited signal-to-noise ratio and picosecond timing resolution. However, SPAD detectors require a guard-ring structure to prevent lateral ...

High-efficiency fill factor recovery using refractive microlens arrays imprinted on 0.5–256 kpixel front-side illuminated SPAD imagers

Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic, Scott Anthony Lindner, Tommaso Milanese, Ermanno Bernasconi, Vladimir Pesic, Frédéric Zanella

Silicon-based single-photon avalanche diodes (SPADs) implemented in front-side illuminated arrays and imagers have often suffered from fill factor limitations. The corresponding reduced sensitivity can be sometimes traded off with longer acquisition times ...

Design and modeling of self-aligned nano-imprinted sub-micrometer pentacene-based organic thin-film transistors

Christian Enz, Jean-Michel Sallese, Rolando Ferrini, Randoald Müller, Frédéric Zanella, Nenad Marjanovic

Sub-micrometer channel length (0.5 mu m) organic thin-film transistors (OTFTs) are demonstrated using a process flow combining nano-imprint lithography (NIL) and self-alignment (SA). A dedicated test structure was designed and samples were fabricated on 4- ...
