Usually, laser drilling with standard single femtosecond pulses results in tapered holes of strongly limited length and rough inner surface.<\/p>\n<p>This new laser-matter interaction regime makes it possible to directly drill holes of high aspect ratio in one single step without any chemical etching. The choice of the laser-burst parameters was revealed to be very important in order to achieve an outstanding micromachining quality of the machined structures. The femtosecond laser GHz-burst mode could pave the way for new applications such as microelectronics where silicon interposers are likely to be replaced by glass interposers.<\/p>\n","protected":false},"featured_media":13327,"parent":0,"template":"","secteur":[143,146],"class_list":["post-13326","news","type-news","status-publish","has-post-thumbnail","hentry","secteur-143","secteur-146"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
