Design considerations for a high temperature image sensor in 4H-SiC

Abstract: This thesis is part of a project, Working on Venus, funded by the Knut and Alice Wallenberg Foundation (one of the largest Swedish funders of research) and developed by KTH in collaboration with Linkӧping University. The goal of this project is to create a lander able to investigate the planet Venus and to work under extreme conditions, i.e. it has to be able to withstand at high levels of radiation and high temperatures such as that of Venus surface (that is about 460 °C) without integrating a dedicated bulky cooling system to reduce the overall weight and volume of the system. In this thesis it will be investigated in detail the 4H-SiC performances to realize a CMOS image sensor for UV photography that operates at high temperature. This work will include discussions and proposals on possible future applications, such as the realization of 4H-SiC phototransistors
