We have developed a three-dimensional (3D) multiprocessing method with femtosecond laser pulses shaped by Computer Generated Hologram (CGH). In this paper, we consider microdrilling of various sheet materials such as glass, polymer and metal, using our method. We design a CGH with long-focal-depth for focusing femtosecond laser pulses.

Doping is one of the challenges for silicon carbide (SiC) device fabrication due to its hardness, chemical inertness and the low diffusion coefficient of most impurities. A laser doping technique is chosen to dope 4H-SiC by gallium which is incorporated into the semiconductor as p-type dopants. The substrate is simultaneously hea...$28.00
