1. Coherent Inc. Sapphire Scribing with Diode Pumped Solid State Lasers

…Passes. Comments: Laser scribing of sapphire with a Q-switched, ultraviolet laser is a high-precision, non-contact process, which addresses concerns about street width restrictions and chip-edge damage. Specifically, we have shown that laser scribes can readily achieve scribe aspect ratios substantially…

3. Talisker Sapphire Scribing Whitepaper final	Best match in this PDF \| All matches in this PDF
…conventional, mechanical methods for sapphire wafer singulation are diamond scribing and blade dicing. Unfortunately, when using these methods, the low depth of the scribe can lead to failure of the substrate to break along the scribed line, which lowers yields. The major negatives of blade dicing are the… Related Searches: talisker \| 213 nm \| sapphire scribing

4. Coherent Inc. Alumina Drilling and Scribing with CO2 Lasers
…lines were scribed. Successful scribing was achieved on all samples and 35 to 45% cut depth was achieved on both 0.025" and 0.040" thick samples. This cut depth would be sufficient to produce a clean break in the substrate. Fig. 1 - 1-mm Diameter Holes Were Drilled and 10-mm Long Lines Scribed on Alumina… Related Searches: k-250 \| k250 \| glass scribing

5. Coherent Inc. Low k Dielectric Scribing with UV DPSS Lasers
…Results: Laser scribing of a low-k dielectric stack on silicon was performed and the results visualized using a scanning electron microscope. Laser scribing successfully cut through all the dielectric layers, and produced no cracking or delamination. Fig. 1 - An AVIA-X Laser Scribe Line in a Low-k Dielectric… Related Searches: laser scribing \| low-k
