Bio

Renato Turchetta received the Laurea (Master degree) in Physics at Milan University (Italy) in 1988 and the Ph.D. in Applied Physics from the University of Strasbourg (France) in 1991. He was Assistant Professor there until 1999 before moving to the Rutherford Appleton Laboratory, near Oxford (UK), where, since 2005, he leads the CMOS Sensor Design group, which specialises in CMOS image sensors for scientific and other high-end applications. He is co-author of over 100 papers on solid-state detectors, low-noise, microelectronics and CMOS image sensors in international journals as well as of 8 patents on CMOS image sensors. He was on the technical committee of IISW2009 and is a member of the programme committee of Image Sensor Europe since 2011.

Abstract

Larger and faster: CMOS Image Sensors for scientific applications at the Rutherford Appleton Laboratory.

Scientific applications have a variety of specifications, often very demanding. Innovations is instrumental in providing solutions to these high-end problems. The CMOS Sensor Design Group at the Rutherford Appleton Laboratory started working towards this goal since the end of the 90's and this talk presents some of the most recent achievements, centered around two areas: speed and area.

Conventional high speed image sensors are capable of pixel rates around 1010/sec, or 10 gigapixel/sec. In this talk we present a sensor capable of breaking the barrier of the terapixel/sec. This sensor, named Kirana, boasts a 0.7 Mpixel resolution and is capable of 5 millions frames per second. This improvement was achieved by combining charge-coupled device (CCD) and CMOS technology in a single chip.

This talk will also present a wafer-scale sensor, named Lassena. The pixel pitch of the sensor is 50 um which is state-of-art for this type of sensors. Despite its large resolution with 6.7 million pixels, the Lassena sensor can work at video rate and it also has low noise for improved sensitivity. As many applications, for example in medical field, where large area sensors are needed, demand even larger area coverage, the sensor was designed so that pixels can go right to the edge of 3 of their sides. The technology to achieve this is patented and will be presented in this talk.
