Advanced MCT technologies at LETI for space applications

Abstract
This document is a recap of an oral presentation made at Nice during the INSU Astrophysics Detector Workshop 2008. It aims at giving an overview of the achievements and ongoing developments presently carried out at CEA-LETI in the field of Infrared focal plane array. Although most of the research actually performed at LETI is not driven by space oriented application, the excellence and the cutting edge of the outcome is or can be applied to space-dedicated components. This paper focus on features and developments from which astrophysics observation would benefit in the near future on the European market. This encompassed “traditionnal” developments such as format enlargement, low dark current technology such as p/n structure but it also shade light on promising and thrilling development such as avalanche photodiode array. It eventually gives some hints of none MCT technologies processed at LETI.
