PhD researcher on ultralow power design techniques for thin-film VLSI circuits
The goal of this PhD is to elaborate ultralow power design techniques for flexible integrated circuits. The technology that we will use are transistors that are processed on flexible plastic substrates. They are based on amorphous oxide semiconductors, kin to the transistors used in the backplanes of AMOLED televisions, but processed on plastic. Our goal is to use them to make flexible integrated circuits with large integration densities, from LSI to VLSI. These flexible circuits will find applications in IoT and wearable patches that measure body functions.
The target thin-film circuits for IoT and wearables need to interact with standard electronics and readers (such as smartphone, bluetooth, ...). This requirement sets minimum specifications regarding power consumption, supply voltage and operating speed. The challenge in the research is to reach these despite certain technology performance limitations. Indeed, the semiconductor has a charge carrier mobility of about 20 cm2/Vs, and can only carry electrons, meaning that only n-type transistors exist. Furthermore, the transistor dimensions are not strongly scaled, and of the order of 0.5 to 2 microns.

PhD researcher on design of ultrathin image sensors using thin-film transistor matrix
Imec develops disruptive technologies for image sensors based on thin-film photodetectors. Ultra-thin, submicron active layers with absorption coefficients much higher than those of e.g. silicon enable new form factors and applications. When integrated with a thin-film transistor backplane, thin-film photodetectors can serve as a basis for large-area, flexible image sensors that find use in medical or industrial x-ray imaging, in consumer applications such as fingerprint or handpalm scanners, or for conformable, curved focal planes.
