2. 16. Process Design Kit and High-Temperature Digital ASICs in Silicon Carbide

   Author : Muhammad Shakir; Carl-Mikael Zetterling; B. Gunnar Malm; Philip Mawby; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon Carbide; high-temperature digital integrated circuits; process design kit PDK ; bipolar logic gates; transistor-transistor logic TTL ; TTL CPU; bipolar transistor; LSI Circuits; ASICs; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Electronics such as microprocessors are highly demanded to monitor or control a process or operation in temperature critical (300 ºC to 600 °C) applications. State-of-the-art silicon-based integrated circuits (ICs) have been improved significantly throughout the years but mainly for a low-temperature ambient. READ MORE

4. 17. Ohmic Contacts for High Temperature Integrated Circuits in Silicon Carbide

   Author : Katarina Smedfors; Carl-Mikael Zetterling; Niklas Rorsman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : In electrical devices and integrated circuits, ohmic contacts are necessary and a prerequisite for the current transport over the metal-semiconductor junctions. At the same time, a desired property of the ohmic contacts is to not add resistance or in other way disturb the performance. READ MORE

5. 18. Radiation Hardness of 4H-SiC Devices and Circuits

   Author : Sethu Saveda Suvanam; Anders Hallén; Carl-Mikael Zetterling; Ulrike Grossner; KTH; []
   Keywords : Silicon carbide; radiation hardness; protons; gamma radiation; bipolar junction transistors; aluminium oxide; surface recombination.; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Advances in space and nuclear technologies are limited by the capabilities of the conventional silicon (Si) electronics. Hence, there is a need to explore materials beyond Si with enhanced properties to operate in extreme environments. In this regards, silicon carbide (4H-SiC), a wide bandgap semiconductor, provides suitable solutions. READ MORE

6. 19. SiC Readout IC for High Temperature Seismic Sensor System

   Author : Ye Tian; Carl-Mikael Zetterling; Ana Rusu; Philip A. Mawby; KTH; []
