Flat Excimer Market Summary

A Flat Excimer typically refers to a flat-type excimer lamp or flat excimer light source, which is a specialized form of excimer ultraviolet (UV) light technology designed in a flat, planar structure. These devices are used primarily for surface treatment, sterilization, photolithography, and materials processing, especially where uniform, large-area UV irradiation is needed.

According to the new market research report "Global Flat Excimer Market Report 2025-2031", published by QYResearch, the global Flat Excimer market size is projected to reach USD 0.11 billion by 2031, at a CAGR of 4.4% during the forecast period.

Market Drivers:

Growing demand for low-temperature dry surface treatment in display, semiconductor, and precision electronics manufacturing: Flat excimer lamps are typically based on 172 nm vacuum ultraviolet light. Their high photon energy can break molecular bonds in organic contaminants and generate active oxygen and ozone in oxygen-containing environments, enabling dry cleaning, organic residue removal, hydrophilicity improvement, coating pretreatment, and adhesion enhancement. Compared with plasma treatment, wet cleaning, or high-temperature processing, excimer lamps offer low-temperature, dry, inline-compatible, and heat-sensitive-material-friendly processing advantages. As a result, demand is increasing in flat panel displays, semiconductor packaging, flexible electronics, optical films, touch panels, and precision coating pretreatment. Official materials from Hamamatsu and Ushio position 172 nm excimer light sources for dry cleaning, surface modification, hydrophilicity improvement, and adhesion enhancement.

Expanding surface modification demand for polymers, films, glass, and metals: Flat excimer lamps can be used to treat resin, rubber, metal, glass, film, coating substrates, and other materials to improve wettability, printability, coating adhesion, and bonding strength. As automotive electronics, packaging films, optical materials, medical consumables, electronic adhesives, composite materials, and precision coating industries require tighter control of surface energy, VUV excimer treatment is gradually expanding from laboratories and high-end electronics manufacturing into broader industrial material processing. Ushio Europe states that 172 nm excimer light has photon energy of about 7.23 eV, strong enough to break many important organic molecular bonds, making it suitable for production processes requiring surface pretreatment.

Rising acceptance driven by mercury-free and environmentally friendly UV source replacement: Conventional low-pressure mercury lamps have been widely used in industrial UV processing, but they face limitations related to mercury content, warm-up time, thermal impact, and energy efficiency. Excimer lamps are generally mercury-free, instantly switchable, low-temperature, wavelength-concentrated, and highly controllable, which aligns with equipment upgrade trends under stricter environmental and process requirements. Ushio's 172 nm excimer lamp materials highlight mercury-free operation, low heat generation, instantaneous ignition, and suitability for temperature-sensitive materials, supporting substitution opportunities in selected traditional UV treatment processes.

Restraint:

High equipment and process-integration costs: A flat excimer lamp is not a simple drop-in replacement for a conventional UV lamp. Industrial deployment usually requires matching power supplies, cooling systems, nitrogen or controlled atmospheres, irradiation-distance control, conveyor mechanisms, shielding, exhaust, and monitoring systems. For customers in displays, semiconductors, optical films, and precision coating, adoption requires process validation, yield evaluation, and production-line compatibility testing. This creates relatively high upfront investment and long qualification cycles, limiting rapid adoption among small and medium-sized customers.

High requirements for VUV source lifetime, uniformity, and stability: The key competitiveness of flat excimer lamps is not only their ability to emit 172 nm VUV light, but also large-area irradiation uniformity, output stability, lamp lifetime, window-material transmittance, thermal management, and long-term reliability. In display, semiconductor, and high-end coating applications, insufficient uniformity or rapid output decay can cause inconsistent surface treatment, adhesion fluctuation, incomplete cleaning, or yield loss. Therefore, customers have high requirements for lamp design, sealing technology, power-supply matching, and quality control.

Application boundaries caused by material compatibility and process-window limitations: Excimer lamps are effective for organic contaminant removal, surface activation, and hydrophilic modification, but they are not suitable for every material or contaminant type. Hamamatsu notes that dry cleaning can decompose and remove organic materials but cannot remove inorganic materials; it also warns that when halogen-containing materials are irradiated by vacuum UV light, decomposition products may adversely affect the excimer lamp light source. Therefore, practical use requires validation based on material type, contaminant type, treatment time, atmosphere, and downstream process requirements.

Opportunity:

High-end application potential in advanced semiconductor packaging, display panels, and optical film manufacturing: With the development of advanced packaging, Mini/Micro LED, OLED, flexible displays, touch modules, and high-end optical films, manufacturing processes increasingly require trace organic contaminant removal, surface energy control, coating uniformity, and bonding reliability. Flat excimer lamps are suitable for large-area, low-temperature, non-contact surface treatment and can be used in substrate cleaning, pretreatment before bonding, surface activation before coating, and optical-material modification. Ushio's UV/excimer irradiation systems are positioned for cleaning and modification in manufacturing fields including flat panel displays, semiconductors, and automobiles.

Upgrade from standalone light sources to modular, equipment-level, inline processing systems: Future opportunities will not be limited to lamp tubes themselves, but will increasingly come from complete solutions integrating light source, power supply, cooling, atmosphere control, conveyor platform, and process parameter know-how. Customers are paying more attention to treatment uniformity, throughput matching, automation integration, inline inspection, and ease of maintenance. Suppliers with system-integration capabilities can capture higher unit value and stronger customer stickiness. For domestic manufacturers, breakthroughs in stable light sources, window materials, driving power supplies, and large-area uniform irradiation could create import-substitution opportunities in display, electronic materials, and industrial surface treatment equipment.

Replacement of wet processes through environmentally friendly dry cleaning and low-temperature surface treatment: In electronics manufacturing and material processing, reducing chemical cleaning agents, lowering wastewater treatment pressure, and improving process cleanliness are long-term trends. Excimer lamps can achieve dry cleaning and surface activation through VUV photochemical reactions, potentially replacing or reducing wet cleaning, primer use, flame treatment, and selected plasma treatment steps in certain applications. This gives flat excimer lamps long-term growth potential in heat-sensitive materials, flexible substrates, high-cleanliness production lines, and environmentally constrained processes.
