21. Silicon and Quartz Microengineering : Processing and Characterisation
Sammanfattning : Microengineering has developed a broad range of production techniques to reduce size, increase throughput, and reduce cost of electrical and mechanical devices. The miniaturisation has also entailed entirely new opportunities. LÄS MER
22. Design Optimization and Realization of 4H-SiC Bipolar Junction Transistors
Sammanfattning : 4H-SiC-based bipolar junction transistors (BJTs) are attractive devices for high-voltage and high-temperature operations due to their high current capability, low specific on-resistance, and process simplicity. To extend the potential of SiC BJTs to power electronic industrial applications, it is essential to realize high-efficient devices with high-current and low-loss by a reliable and wafer-scale fabrication process.
