Plan Optik AG (Elsoff, Germany) and 4JET microtech (Alsdorf, Germany) have jointly developed a process chain for the highly productive production of metallized through-glass vias.<\/p>\n<p>The new VLIS process (short for Volume Laser Induced Structuring) enables the production of high-precision TGV (\u201eThrough Glass Vias\u201c) for advanced packaging in glass wafers, or substrates for displays.<\/p>\n<p>TGV are micro-holes with a diameter of typically 10\u00b5m to 100\u00b5m. For various applications in the advanced packaging sector, tens of thousands of these vias are applied per wafer and metallized to produce the required conductivity. TGVs are also used in the manufacture of displays, for example based on \u00b5LED. Previous methods for manufacturing were slow, associated with high reject rates and difficult to match to the metallization process.<\/p>\n<p>The teams from both companies have now developed a solution that can prepare several 10,000 vias per minute, which are etched in a subsequent batch process to be coated afterwards. The resulting channels are positioned with a hole-to-hole accuracy better than +\/- 2\u00b5m. The substrates are free of microcracks, and the insides of the channels are smooth-walled and can be homogeneously metallized. The process is suitable for glass types typical in the semiconductor and display industry. In addition to glass starting thicknesses of 100\u00b5m, various copper layers down to 25\u00b5m thickness can be realized.<\/p>\n<p>The two partners have agreed on a cooperation that provides users with a high degree of flexibility: Customers can either purchase components produced with VLIS from Plan Optik, or purchase qualified total solutions for system technology including laser systems, wet chemistry and metallization from 4JET and partners.<\/p>\n<p>Plan Optik already has a modern production chain for the manufacture of glass wafers and masters all process steps from wafer cutting and edge processing, through structuring and cleaning, to metallization. The addition of 4JET\u2019s system technology now enables the rapid and positionally accurate modification of substrates. A modified version of the proven 4JET laser systems for cutting glass is used. The PEARL platform is already used for cutting glass substrates in display, architectural glass, or medical technology. Depending on the version, the systems are capable of high-precision modification of glass up to 2.2 m wide and more than 3 m long.<\/p>\n<p><strong>A new technology<\/strong><\/p>\n<p>The use of laser technology for selective etching is not new, but overall the cooperation delivers significant advances for customers: the combination with Plan Optik AG\u2019s extensive process chain creates the world\u2019s leading solution chain for fully processed and metallized TGV wafers. At the same time, the precision, speed and availability now achievable on very large substrates enables application in display manufacturing for the first time.<\/p>\n<p>The two partners see further potential for the VLIS process for glass-based MEMS, microfluidics or high-frequency antenna technology (e.g. 6G).<\/p>\n<p>The PEARL systems are based on a granite machine platform that offers inherent accuracy and long-term stability. Cutting geometries and positions for interposers can be easily imported from CAD drawings. Targeted tuning of axis controls results not only in high cutting speed, but also in excellent path accuracy to achieve high-precision machining. The PEARL DYNAMIC FOCUS ensures that the focus is always within the process window without increasing the process time.<\/p>\n<p>For more information, visit <a href=\"https:\/\/vlis.tech\/\" target=\"_blank\"><strong>> vlis.tech<\/strong><\/a>.<\/p>\n<p><strong>Plan Optik AG<\/strong><\/p>\n<p>As a technology leader, Plan Optik AG produces structured wafers at sites in Germany and Hungary.
