What ORC MANUFACTURING does

ORC Manufacturing Co., Ltd. (株式会社オーク製作所), founded in 1968 and headquartered in Machida, Tokyo, is a privately held Japanese manufacturer specializing in UV light source technology and precision optical exposure systems. Its product portfolio spans four pillars: (1) UV light sources — including discharge lamps, mercury-free Smart Excimer UV lamps, fluorescent excimer lamps, and UV-LED systems; (2) semiconductor and PCB exposure equipment — PPS steppers (wafer-level and panel-level packaging), FDi/EDi/RDi/Mms direct imaging systems, and excimer laser processing (Exa-Ms5); (3) ozone-related products — AirVenus series and RoomiAir for sterilization and deodorization using proprietary NOx-free Pure O Technology; and (4) UV measurement instruments and JCSS-accredited calibration services. The company operates two manufacturing facilities (Hinode Factory in Tokyo and Suwa Office in Nagano), with a new cleanroom completed in April 2026 dedicated to AI semiconductor advanced packaging lithography equipment.

The business model is B2B capital equipment sales supplemented by recurring replacement-lamp revenue and metrology services. Products are sold through direct sales offices in Tokyo and Osaka, industry exhibitions (JPCA Show, Nepcon Japan, SEMICON Japan, ASTEC), and a multilingual website (Japanese, English, Chinese, Korean). Pricing is custom-quotation based on specifications, configuration, and volume, with multi-year contracts typical for capital equipment. Primary customer segments are semiconductor manufacturers (especially AI packaging), PCB/substrate producers (FC-BGA, FC-CSP, AiP, HDI, flexible), display manufacturers, automotive electronics suppliers, and healthcare/medical OEMs.

ORC differentiates through proprietary technology — Smart Excimer mercury-free UV lamps, Pure O Technology for NOx-free ozone, D-A-T high-precision compensation achieving 6μm accuracy, and proprietary alignment correction delivering 3.5μm overlay on FDi-MP systems. The company holds JCSS calibration accreditation (registration 0351, optical category, since July 2021), ISO 9001 quality certification (since 1997), and ISO 14001 environmental certification across both factories. All products are manufactured domestically in Japan.

Broad incumbents

• Canon Inc. Canon's FPA series i-line steppers serve semiconductor packaging lithography, overlapping with ORC's PPS stepper product line. Much larger company with a broad camera/imaging portfolio; competes with ORC in select packaging and MEMS lithography applications.
• Veeco Instruments: Veeco provides precision processing and metrology equipment for semiconductor and advanced packaging applications, including lithography and inspection systems. Adjacent competitor to ORC's exposure equipment business with broader portfolio across data storage, semiconductor, and compound semiconductor markets.
• Nikon Corporation: Nikon Precision's NSR-series i-line and ArF immersion steppers target semiconductor lithography including advanced packaging. Much larger diversified corporation, but its lithography systems overlap technically with ORC's wafer-level and panel-level packaging steppers.
• ASML Holding: ASML is the dominant semiconductor lithography vendor globally with EUV and DUV systems. While operating at a vastly larger scale and in adjacent (not directly overlapping) lithography segments, it sets the competitive frontier in semiconductor exposure technology relevant to ORC's packaging lithography niche.

Direct peers

• Hamamatsu Photonics: Hamamatsu Photonics manufactures UV light sources, photocure lamps, and photonic devices for semiconductor and life science applications. Overlaps with ORC's UV lamp and UV irradiation system business, and is a fellow Japan-based photonics specialist.
• Phoseon Technology: Phoseon is a specialist in UV-LED curing systems for industrial printing, coating, and electronics manufacturing. Overlaps with ORC's UV-LED light source units and industrial UV curing exposure systems, particularly in PCB and electronics applications.
• Ushio Inc. Ushio is a Japan-based manufacturer of UV lamps and projection/exposure systems for semiconductor and display manufacturing. Strong overlap with ORC's UV light source portfolio (discharge lamps, excimer UV lamps) and lithography equipment offerings.
• SCREEN Holdings (formerly Dainippon Screen): SCREEN's Semiconductor & Display Solutions segment produces DE series direct imaging systems for advanced PCB and package substrate lithography, directly competing with ORC's FDi, EDi, and RDi series. Overlapping product line targeting FC-BGA and FC-CSP substrate manufacturers makes it the most comparable peer.
• Excelitas Technologies: Excelitas manufactures specialty UV curing lamps, mercury arc lamps, and photonic components for industrial curing and printing applications. Direct overlap with ORC's discharge lamp and UV irradiation equipment offerings.

Emerging players

• MKS Instruments: MKS Instruments (including its Newport and Ophir brands) supplies UV/laser measurement instruments, radiometers, and photodetectors. Directly comparable to ORC's UV measurement instrument business (UV-365LED, UV-M series, UV-351 series) and calibration services.
