The TGV sapphire wafer with laser-drilled apertures is an advanced substrate material fabricated by forming high-precision through-glass vias (TGV) on single-crystal sapphire (Al₂O₃) substrates via laser or etching processes. It combines sapphire’s exceptional hardness, high-temperature resistance, and optical transparency with TGV’s micro/nano-structuring capabilities.
