Résumé

We present the first flexible dual-side single-photon avalanche diode (SPAD) image sensor in array format. The image sensor comprises 32x32 pixels, whereas a special layout and fabrication flow were developed to fabricate the sensor. SPAD breakdown voltage, noise, sensitivity and crosstalk were thoroughly analyzed. The sensor is operated both in frontside- (FSI) and backside-illumination (BSI), whereas a dual-objective camera demo was built to simultaneously demonstrate the sensor in FSI and BSI modes.

Capteur photographique

Un capteur photographique est un composant électronique photosensible servant à convertir un rayonnement électromagnétique (UV, visible ou IR) en un signal électrique analogique. Ce signal est ensuite amplifié, puis numérisé par un convertisseur analogique-numérique et enfin traité pour obtenir une . Le capteur est donc le composant de base des appareils photo et des caméras numériques, l'équivalent du film (ou pellicule) en photographie argentique.

Active-pixel sensor

An active-pixel sensor (APS) is an , which was invented by Peter J.W. Noble in 1968, where each pixel sensor unit cell has a photodetector (typically a pinned photodiode) and one or more active transistors. In a metal–oxide–semiconductor (MOS) active-pixel sensor, MOS field-effect transistors (MOSFETs) are used as amplifiers. There are different types of APS, including the early NMOS APS and the now much more common complementary MOS (CMOS) APS, also known as the CMOS sensor.

Back-illuminated sensor

A back-illuminated sensor, also known as backside illumination (BI) sensor, is a type of digital that uses a novel arrangement of the imaging elements to increase the amount of light captured and thereby improve low-light performance. The technique was used for some time in specialized roles like low-light security cameras and astronomy sensors, but was complex to build and required further refinement to become widely used. Sony was the first to reduce these problems and their costs sufficiently to introduce a 5-megapixel 1.
