Abstract:

The application of reliable laser sources is well-established in several fields of industry including automotive, electronics, and medical manufacturing on macro, micro, and even nanometer scales [1]. In modern semiconductor technology, silicon is the dominating material. Further materials like gallium nitride (GaN) and silicon carbide (SiC) allow for higher operating frequencies and power levels, i. e., high-speed electronics and high-power applications. However, their chemical and physical properties do not only allow extending the limits of silicon-based device performance, but also call for alternative methods of processing.
