3. Vertical High-Voltage Transistors on Thick Silicon-on-Insulator
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : More and more electronic products, like battery chargers and power supplies, as well as applications in telecommunications and automotive electronics are based on System-on-Chip solutions, where signal processing and power devices are integrated on the same chip. The integration of different functional units offers many advantages in terms of reliability, reduced power consumption, weight and space reduction, leading to products with better performance at a hopefully lower price.
