Corporate History
Foundation and Abrasive Wheel Origins(1937–1968) Founded in 1937 as Dai-Ichi Seitosho Co., Ltd. in Hiroshima, the business began by manufacturing industrial abrasive grinding wheels. In the 1950s, the company developed ultra-thin resinoid blades, establishing the technical foundation for precision micro-abrasive cutting.
Semiconductor Pivot and Name Transformation(1969–1989) In 1969, the company introduced the “Dicing Saw,” applying abrasive blade slicing directly to semiconductor silicon wafers. Rebranding to DISCO Corporation in 1977(an acronym for Dai-Ichi Seitosho Company), the firm expanded globally across the US and Europe, capturing key market share as silicon wafer manufacturing scaled worldwide.
Technology Diversification and Laser Innovation(1990–2010) DISCO broadened its core competencies beyond mechanical dicing saws to surface grinders, chemical-mechanical polishers, and advanced laser-based cutting systems, including stealth dicing and laser ablation. It developed proprietary technologies such as KABRA(laser slicing for silicon carbide wafers).
Advanced Packaging and AI Era(2011–Present) With the rise of high-performance computing, 2.5D/3D chiplet integration, and High Bandwidth Memory(HBM), DISCO’s ultra-precision grinding and thinning technologies became critical process enablers. The company successfully scaled its dual model of precision processing tools and capital equipment to record consolidated revenues.
Business Model and Strategic Mechanics
DISCO operates a classic “Razor-and-Blade” business model adapted for advanced industrial manufacturing, generating profits across capital machinery, recurring consumables, and technical application services.
Think Insights
- Capital Equipment(The Razor): DISCO designs and sells precision processing machines, including mechanical dicing saws, surface grinders, dry polishers, and laser cutters. Equipment sales account for approximately 60% to 65% of revenue. Equipment gross margins remain exceptionally high because of DISCO’s near-monopolistic market share, specialized motion control, and high barrier to entry against competitors like Tokyo Seimitsu(Accretech). note
- Precision Processing Tools(The Blade): Wafer cutting blades, grinding wheels, and diamond abrasive pads wear down continuously during wafer thinning and die separation. These recurring consumable sales generate roughly 18% to 22% of revenue with gross margins frequently exceeding 50%. Because DISCO optimizes equipment parameters to its own patented blade metallurgy and diamond grit dispersion, clients face severe yield risks if attempting third-party consumable substitution. DISCO CORPORATION
- Engineering Services and Processing Contracts: DISCO maintains global applications laboratories. Customers send new materials(such as GaN, SiC, glass substrates, and multi-layer stacked dies) for contract recipe testing, which creates early design lock-in before manufacturing lines order mass-production equipment.
- Financial Performance: For fiscal year 2025, consolidated net sales reached ¥436.89 billion, generating an operating profit of ¥184.99 billion—representing an operating margin of 42.3% and a net profit margin of 31.0%. DISCO CORPORATION+ 1

AI Strategic Positioning, CapEx, and Industrial Partnerships
DISCO approaches artificial intelligence from two directions: capturing the structural hardware demand generated by AI accelerators, and integrating AI into factory operations and equipment diagnostics.
- Hardware Processing for High Bandwidth Memory(HBM): Advanced AI accelerators(such as NVIDIA Blackwell and AMD Instinct lines) rely on HBM stacks(HBM3e and HBM4) comprised of 8 to 16 vertically stacked DRAM dies. To maintain overall package height limits and optimize through-silicon via(TSV) conductivity, each DRAM wafer must be mechanically ground to thicknesses below 30 to 40 micrometers without micro-cracking. DISCO’s ultra-precision grinding and chemical dry polishing tools serve as the standard production equipment for primary HBM memory suppliers, including SK Hynix, Samsung Electronics, and Micron Technology.
- Advanced Packaging and Glass Substrates: CoWoS(Chip-on-Wafer-on-Substrate) and panel-level packaging require precision dicing of reconstituted wafers and composite materials prone to internal stresses. DISCO partners closely with TSMC, Intel, and leading OSATs(ASE Group, Amkor) to co-develop dicing recipes for advanced multi-die architectures and emerging glass core substrates.
- Operational AI and Internal System Budgets: Internally, DISCO utilizes automated vision inspection algorithms and predictive machine learning models within its dicing platforms to correct blade trajectory and detect chipping in real time. The company allocates approximately ¥20 billion to ¥25 billion annually to total R&D expenditures, prioritizing wafer-level laser processes, automation, and AI-assisted defect recognition.
- Capital Investments: To meet structural demand driven by generative AI and advanced packaging, DISCO has committed multi-billion-yen capital outlays toward facility expansions, including its Hiroshima Kuwabara and Kure manufacturing complexes, ensuring capacity meets accelerated multi-layer packaging production.
