UV lasers are ideal for small, precise holes of plastic
Apr 16 , 2021
Laser technology has many advantages over traditional drilling methods. It enables more precise drilling, makes no mechanical contact with plastic parts and lets you switch between hole sizes and shapes quickly and easily. Depending on the order you need to fill, you may require different hole sizes for a specific part. Thanks to laser drilling, you can stock undrilled parts and then drill the req...

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...

Method for testing for blind hole formed in wafer layer
Apr 19 , 2021
A new method for detecting blind holes in the contact layer of a multi-chip semiconductor test wafer makes use of the fact that if the hole is not a blind hole, a subsequent etch step extends the hole a predetermined distance into the layer immediately underlying the contact layer. After a predetermined number of holes have been etched through the contact layer and for a predetermined distance int...

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...

How to Engrave on Plastic by 355nm laser
Apr 23 , 2021
How to Engrave on Plastic by 355nm laser Methods of laser marking on plastics Foaming Foaming leaves a tangible mark on the material. It can be seen as laser-induced boiling, which melts the surface. Due to the rapid cooling, bubbles are encapsulated in the material. These bubbles leave a positive mark, which is tangible. The laser works on a low power level and longer pulses. Foaming works on all...
