Global TGV (Through Glass Via) Foundry Market Strategic Research Report

Scope of the Report

The global TGV (Through Glass Via) Foundry market size is predicted to grow from US$ 144 million in 2025 to US$ 493 million in 2032; it is expected to grow at a CAGR of 19.6% from 2026 to 2032.

Through-glass via (TGV) foundry refers to the process of making tiny vertical through holes (usually with a diameter of 10μm~100μm) on high-quality borosilicate glass or quartz glass substrates through a series of high-precision processes, and filling these through holes with conductive materials (such as copper) to achieve electrical connections. This technology uses laser etching, inductively coupled plasma dry etching and other methods to prepare through holes. It has the advantages of excellent high-frequency electrical properties, strong mechanical stability, low cost, and simple process flow. It has broad application prospects in the fields of precision devices such as Mini/Micro LED direct display and semiconductor advanced packaging substrates. In 2024, global TGV Substrate production reached approximately 4,000 K Pcs, with an average global market price of around US$ 30 per piece.

TGV substrates exhibit excellent high-frequency electrical properties. The dielectric constant of glass is approximately one-third that of silicon, and the dissipation factor is two to three orders of magnitude lower than silicon. This significantly reduces substrate losses and parasitic effects, ensuring signal integrity. TGV substrate production eliminates the need for complex insulating layer deposition processes, and thinning is not required in the ultra-thin interposer, streamlining the production process and improving efficiency. Due to the readily available availability of large-scale, ultra-thin panel glass and the elimination of the need for insulating layer deposition on the substrate surface or the inner walls of the TGV, production costs are significantly reduced. Even with an interposer thickness less than 100μm, warpage remains minimal, ensuring the stability and reliability of the package structure. TGV substrates offer unique advantages in applications such as RF chips, high-end MEMS sensors, and high-density system integration, making them a preferred choice for next-generation high-frequency chip 3D packaging.

The Through Glass Via (TGV) foundry market is entering a rapid growth phase, driven by demand for high-density interconnects in advanced packaging, photonics, MEMS, and RF modules. Over the next five years, adoption will accelerate as TGV technology enables superior electrical performance, thermal stability, and miniaturization compared to traditional substrates. Asia—especially China, Japan, and South Korea—is expected to lead in scaling production capacity, while North America and Europe focus on high-reliability and defense-related applications. With its high technical barriers and expanding use in 2.5D/3D integration, the TGV foundry segment is projected to achieve strong profitability as yield, automation, and panel-level processing improve.
