The TOPTICA TopWave DUV is an industrial continuous-wave (CW) deep-ultraviolet laser platform designed for demanding scientific, semiconductor, and industrial applications requiring stable and reliable UV illumination.

The TopWave DUV family is available in 228.5 nm, 257 nm, and 266 nm configurations, providing several deep-UV wavelengths for different material-processing, metrology, spectroscopy, and lithography requirements.

A major advantage of the TopWave DUV is its focus on long-term industrial reliability. TOPTICA specifies a lifetime of more than 10,000 hours, supported by a sealed UV beam path and automated optics shifter. This architecture is particularly important for DUV systems because UV radiation can accelerate degradation of optical components over time.

The laser also provides below 0.1% RMS noise, enabling high signal-to-noise measurements where small changes in optical intensity can affect measurement accuracy.

The TopWave DUV is designed with OEM integration in mind. Its turnkey architecture, passive cooling, and high-quality components allow the laser to be integrated into larger analytical, inspection, metrology, and manufacturing systems without requiring the complexity typically associated with laboratory-scale UV laser systems.

For applications operating outside tightly controlled laboratory environments, TOPTICA offers an optional closed-loop chiller. Although the TopWave can operate without a chiller under specified conditions, the chiller can help improve thermal stability and reduce warm-up time.

1. Semiconductor Inspection & Metrology

• Semiconductor Inspection
• Wafer Inspection
• Optical Metrology
• Critical Dimension Measurement
• Thin-Film Characterization
• Defect Inspection
• Surface Metrology

DUV wavelengths are particularly valuable for semiconductor inspection and metrology as semiconductor structures become smaller and increasingly complex. TOPTICA identifies semiconductor inspection and metrology as one of the key application areas for TopWave DUV.

2. Laser-Based Mask Writing

• Photomask Fabrication
• Laser Mask Writing
• Direct Pattern Writing
• Semiconductor Lithography
• Microfabrication

Laser-based mask writing uses a focused laser beam to directly generate precise features without requiring a conventional physical reticle, providing flexibility in semiconductor mask fabrication.

3. Raman Spectroscopy

• Deep-UV Raman Spectroscopy
• Raman Spectroscopy of Inorganic Materials
• Material Characterization
• Chemical Analysis
• Spectroscopic Instrumentation

Deep-UV excitation can be particularly advantageous for Raman spectroscopy of inorganic materials where fluorescence can interfere with conventional visible excitation. Raman intensity also increases strongly toward shorter excitation wavelengths, approximately following a 1/λ⁴ dependence.

4. Interference Lithography

• Interference Lithography
• Microstructure Fabrication
• Nanostructure Fabrication
• Photonic Structures
• Optical Gratings

High coherence, low frequency drift, and good beam quality are important for producing accurate interference patterns. Watt-level laser systems can also enable large-area processing with shorter exposure times, although the available power depends on the specific TopWave DUV configuration.

5. Lithography & Microfabrication

• Semiconductor Patterning
• Microfabrication
• 3D Microprinting
• Holographic Optics
• Transparent Displays
• Photonic Device Fabrication
• Micro- and Nanostructuring

The TopWave DUV is designed for applications where UV laser light is used as a precision tool for patterning and fabrication.
