Korean patent strengthens LPKF’s global leadership in precision laser-based glass structuring with LIDE technology

LPKF LIDE Tools are available for both HVM as well as R&D applications

(IN BRIEF) LPKF Laser & Electronics SE has obtained new patent protection in Korea for its LIDE (Laser Induced Deep Etching) technology, effective September 1, 2025. The process enables ultra-precise, damage-free structuring of thin glass substrates, with applications across semiconductor and microsystem manufacturing. The patented two-stage method creates the distinctive “earthworm structure” in Through Glass Vias, a hallmark of LPKF’s proprietary approach. According to Roman Ostholt, Managing Director LIDE at LPKF, the recognition underscores the company’s pioneering work and strengthens its position in Korea, a key semiconductor market. With LIDE tools available for both high-volume manufacturing and R&D, the new IP rights bolster LPKF’s roadmap for advanced packaging and co-packaging optics while enhancing its global leadership in precision glass processing.

(PRESS RELEASE) GARBSEN/ SEOUL, 3-Sep-2025 — /EuropaWire/ — LPKF Laser & Electronics SE has expanded its international intellectual property portfolio with new patent protection for its pioneering LIDE (Laser Induced Deep Etching) technology granted by the Korean Patent Office, effective September 1, 2025. This achievement reinforces the company’s strong global position in precision glass processing and secures additional IP rights in one of the world’s most important markets for semiconductor innovation.

The patented LIDE process delivers unparalleled accuracy in micro-structuring thin glass substrates without causing damage, a capability essential for next-generation semiconductor and microsystem manufacturing. A defining aspect of the technology is its distinctive two-stage processing method, which produces highly controlled blister chain formations that create the characteristic “earthworm structure” in Through Glass Vias (TGV). This unique approach enables manufacturers to achieve defect-free glass structuring with high repeatability and reliability.

Roman Ostholt, Managing Director LIDE at LPKF, emphasized the significance of this development: “The recognition of our LIDE technology by the Korean Patent Office validates our role as an innovation leader in laser-based glass processing. Korea is a crucial hub for advanced semiconductor production, and securing protection here demonstrates our commitment to supporting regional and global high-tech industries with groundbreaking solutions.”

The LIDE platform is increasingly critical for industries facing growing demands for clean, precise, and crack-free glass processing. It offers manufacturers an efficient alternative to traditional glass processing techniques and is well positioned to enable advanced packaging, co-packaging optics, and other frontier applications. LPKF continues to expand its portfolio of LIDE tools for both high-volume manufacturing (HVM) and research and development, ensuring scalability and flexibility for diverse use cases.

By securing new patent rights in Korea, LPKF not only protects its proprietary methodology but also strengthens its competitive edge in global markets. This protection underpins the company’s strategic roadmap for semiconductors and microsystems, extending its technological leadership well beyond Korea and advancing the adoption of LIDE in emerging applications worldwide.
