Capabilities

Ultrafast picosecond/femtosecond laser processes engineered for the hardest problems in 3C and semiconductor production.

01

SiC Wafer Stealth Dicing

Laser stealth cutting of silicon carbide wafers for semiconductor production — internal modification followed by clean tape-expansion separation.

02

Bessel Cutting of Brittle Materials

Kerr-effect self-focusing forms a ~1μm filament through glass and transparent materials — burst-mode cutting with pristine cross-sections.

03

Laser Direct Writing

Innovative laser direct-writing photoresist technology replaces photolithography masks — fast, flexible PCB sample preparation.

04

AlN & Ceramic Cutting

Cutting aluminium nitride and ceramic substrates of different thicknesses, plus SiC rod cutting and wafer hard punching.

05

Laser Slotting

Galvanometer scanner with F-Theta optics delivers precise micro-slots — profile-verified to μm-level depth accuracy.

06

Micro-Nano Structuring

Surface texturing of stainless steel, zirconium, titanium and aluminium for functional and cosmetic finishes.

07

Coating Laser Removal

Selective PVD coating removal and ceramic surface laser heat-treatment discoloration — no masks, no chemicals.

08

Beam Shaping (DOE)

Diffractive optical elements transform Gaussian spots into flat-top beams for uniform energy distribution across the work area.

09

Surface Cleaning

Laser cleaning of silicon carbide material surfaces — contamination removal without contact or abrasives.
