Restraints:

• Manufacturing Complexity and Cost Constraints Hinder Widespread Adoption of Glass TGV Substrates

A major restraint in the Through Glass Vias (TGV) Substrate market is the high manufacturing complexity and associated costs of processing glass substrates. Advanced processes, such as laser drilling, metallization, and via filling, require special apparatus and fine adjustment, resulting in high production costs. Early TGV suffered from slow via processing speed preventing high-volume production, and though faster processes are available they are still capex intensive. There is also a need for high accuracy and severe quality requirement to be met, which can also push up cost. These also hinder large-scale adoption, particularly for smaller manufacturers. As a result, although glass substrates are beneficial in terms of excellent performance, it is difficult to achieve mass production by meeting both performance and cost requirements of a product and rapid commercialization of the product is hindered.

Opportunities:

• Thermal and Power Limitations in Current Packaging Propel Growth and Investment in Glass Substrate Technologies

The Through Glass Vias (TGV) Substrate Market presents significant opportunities driven by growth opportunity to fix the thermal, power, and cost challenges of current packaging technology solutions including HBM and CoWoS, addressing the challenge of high speed connectivity with dies packaged upon conventional interposer substrates, growing cooperatively with HBM and CoWoS, and overcoming the burning issue of Moore’s wall where lager chips need to access memory quicker and/or cheaper than the current methods. Next-generation AI chips and high-speed communication devices available Glass substrates have superior thermal resistance, lower warpage, and better signal transmission. Increasing investment from major industry players including Intel and AMD, and widespread supply chain networks in South Korea, simplify the process of rapid commercialization and scale-up. Moreover, increasing demand for miniaturization and high computing power in the consumer electronics, automotive, and telecom industries would contribute to market growth. manufacturers of TGV and inspection technologies are discovering new opportunities in this emerging landscape as well.

Challenges:

• Technical Integration and Material Compatibility Challenges Delay Mass Production and Widespread Adoption of TGV Substrates.

The Through Glass Vias (TGV) substrate market is constrained by several critical challenges. The high cost and fact that TGV integration is a semiconductor manufacturing is unfortunately a factor of not producing standard products off a standard machine is an unfortunate reality. Thermal expansion mismatch control between glass and other materials also continues to be difficult, and there is increasing risk of damaging the substrate in handling and processing. One of the problems is that the glass substrate material and process is not well standardized, which makes the compatibility a problem through the supply chain. Additionally, the TGV laser drilling second through-put is slow as compared to traditional via formation processes, which further delays mass production schedules of the industry. Finally, strong ecosystem cooperation from equipment suppliers, material suppliers, and chipmakers delays the commercialization of TGV substrates and its wide utilization.
