As semiconductor architectures evolve toward heterogeneous integration, wafer-level optics, and 3D packaging, glass has emerged as a critical material. Its superior thermal stability, dielectric properties, and flatness make it indispensable for interposers, carrier wafers, MEMS, and photonic integration.

Our contactless laser micromachining systems support precise, scalable processing of thin and thick glass substrates, compound semiconductors, and functional coatings. Whether creating through-glass vias (TGVs), dicing fragile wafers, or structuring photonic features, our laser systems enable crack-free, contamination-free processes with sub-micron accuracy.

From R&D labs to high-volume fabs, our cleanroom-compatible platforms support backend wafer processing, advanced packaging, and optoelectronic integration across the semiconductor value chain.
