UV laser drilling of SiC for semiconductor device fabrication
Apr 19 , 2021
Pulsed UV laser processing is used to drill micro holes in silicon carbide (SiC) wafers supporting AlGaN/GaN transistor structures. Direct laser ablation using nanosecond pulses has been proven to provide an efficient way to create through and blind holes in 400 µm thick SiC. When drilling through, openings in the front pads are formed, while blind holes stop ~40 µm before the backside...

Laser drilling of micro-holes in single crystal silicon, indium phosphide and indium antimonide using a continuous wave (CW) 1070 nm fibre laser
Apr 19 , 2021
The laser micro-drilling of “thru” holes, also known as via holes, in Si, InP and InSb semiconductor wafers was studied using millisecond pulse lengths from an IPG Laser Model YLR-2000 CW multimode 2 kW Ytterbium Fibre Laser and a JK400 (400 W) fibre laser, both with 1070 nm wavelength. The flexibility of this laser wavelength and simple pulsing scheme were demonstrated for semiconduct...

RFH UV laser is especially suitable for laser lettering and typing on switch panel
Apr 26 , 2021
RFH UV laser is especially suitable for laser lettering and typing on switch panel In the old days, there were no marked buttons on the switch panel. We would find stickers or handwriting on the surface, which one is "on the light" or "off the light". This method is neither beautiful nor durable. However, since the popularization and application of ultraviolet laser technology in plastic sw...
