High-Speed Substrate Scribing & Controlled Cleaving Solutions
Scantech Laser delivers advanced laser scribing systems engineered for semiconductor wafers, PV solar cells, advanced ceramics, and thin-film microelectronics. Operating with ultra-short pulse regimes, our machines generate clean micro-grooves to facilitate high-yield, distortion-free mechanical separation.
Cold Laser Ablation & Zero Heat-Affected Zone
Traditional mechanical dicing saws and diamond scribing tools introduce thermal shock, edge chipping, and tool wear into brittle substrates. Scantech Laser scribing platforms utilize galvo-steered picosecond, femtosecond, and UV/Green pulsed lasers to sublimate material directly from solid to gas.
This localized energy absorption prevents micro-fracturing and restricts the Heat-Affected Zone (HAZ) to sub-micron dimensions. The result is superior die-strength retention, minimal kerf loss, and zero chemical consumables on your factory floor.
- ✓ Micron-level kerf widths down to < 15 μm
- ✓ Non-contact processing eliminating mechanical stress & tool degradation
- ✓ Closed-loop high-resolution vision tracking for sub-pixel registration

Laser Scribing Methodologies Engineered for Specific Substrates
Selecting the optimal wavelength and laser interaction regime ensures maximum break capability while preventing structural micro-cracking across brittle or multi-layered substrates.
Femtosecond Cold Scribing
Employs ultra-short pulse bursts where energy is deposited into the material faster than lattice vibrations transfer heat. Prevents melt recast, edge burring, and micro-flaking on sensitive semiconductor dies and flexible displays.
Ablative Layer-by-Layer Scribing
Vaporizes thin surface layers sequentially with high pulse repetition rates. Commonly applied in P1, P2, and P3 thin-film photovoltaic scribing (CIGS, Perovskite, CdTe) to isolate conductive layers without damaging underlying films.
Thermal Stress-Guided Scribing
Utilizes targeted localized thermal expansion followed by controlled gas quenching to create deep micro-fractures along precise paths. Allows instant, clean snap-cleaving of glass and sapphire without generating dust or kerf waste.
Pulsed UV & Green Scribing
Ideal for materials with high bandgap energies like alumina ceramics and silicon carbide (SiC). Short UV (355 nm) photons break molecular bonds directly via photo-ablation, yielding smooth channel sidewalls.
Continuous Wave (CW) Fiber Scribing
Delivers high thermal linear velocity for thick metallic foils, structural ceramics, and heavy-duty industrial components requiring deep micro-groove penetration at maximum linear line speeds.
Laser-Assisted Mechanical Scribing
Combines low-power laser pre-heating with mechanical diamond scribing to reduce cutting resistance on hard brittle materials, extending diamond tool lifespans while improving cleavage straightness.

Frequently Asked Technical Questions
Technical guidance provided by Scantech Laser application specialists for global procurement teams and microelectronics process engineers.
Scantech Laser integrates Fiber (1064 nm), Green (532 nm), UV (355 nm), and Ultrafast Picosecond/Femtosecond sources. Fiber lasers excel in metal and opaque ceramics, Green and UV lasers optimize thin-film PV and semiconductor materials, while Femtosecond cold lasers eliminate thermal impact on heat-sensitive polymers and microelectronics.
By deploying ultrafast pulse durations (picosecond/femtosecond) combined with galvo-scanner synchronization and specialized beam shaping, peak energy ablates material within picoseconds—faster than heat diffusion occurs. This results in virtually zero Heat-Affected Zone (HAZ), eliminating mechanical stress and structural micro-cracks.
