Philoptics (161580.KQ), a leader in display laser processing equipment, is making significant inroads into the semiconductor industry with its TGV (Through Glass Via) solution, TRONADA. This cutting-edge technology for semiconductor glass substrates is propelling the company's global market push. In April, Philoptics secured the world’s first mass production reference for a glass substrate manufacturer and is now formalizing partnerships with key glass suppliers, aiming to expand its supply network next year.

At the KPCA Show 2024, held from September 4-6 in Songdo, Incheon, Philoptics showcased TRONADA to hundreds of industry professionals. Instead of displaying the large equipment, the company presented glass substrates processed using its TGV technology, including panels with 50,000 micro-holes and a model featuring 500,000 drilled holes. It also displayed semi-finished glass substrates with copper plating, developed in collaboration with partners.

TRONADA, completed earlier this year and now in mass production, is the world’s first mass-production equipment for creating through-glass vias in glass substrates. This technology enables precise micro-holes for electrode channels, essential for ultra-fine semiconductor packaging.

Glass substrates offer key advantages for advanced packaging, including smooth surfaces, large processing areas, and the ability to reduce substrate thickness by 25%. They also reduce power consumption by over 30% compared to traditional materials. However, the challenge lies in drilling uniform, defect-free micro-holes, where TRONADA excels.

Philoptics’ main competitor in the TGV market is a European firm, but TRONADA is considered superior in processing speed and hole quality. It can handle multiple hole sizes and shapes on a single substrate and has strong cavity processing capabilities, crucial for high-density semiconductor applications.

Shim Sang-won, Director of Philoptics’ Semiconductor Equipment Research Lab, said, "Philoptics is the only company that meets the strict mass production quality standards required by glass substrate manufacturers. While competitors have made progress, TRONADA still leads in processing speed and yield."

With its advanced technology, Philoptics plans to expand its global customer base by the end of the year. Early results from collaborations with major glass substrate manufacturers are promising. While the glass substrate market is still in its early stages, Philoptics is positioning itself to lead the value chain as the market develops.

“Our customer base for TGV equipment continues to grow,” Shim added. “In the second half of this year, we will focus on developing advanced equipment that increases processing speed and drills more holes per unit area.”
