3D Micro Milling

Although conventional chemical or plasma etching

techniques yield high-quality results, they are

often slow and complicated, and provide

limited options for the geometries they

can produce. In addi­tion, in photonic

applications in which sensitive optical

devices are integrated onto silicon

wafers, etching is often not

possible or recommended.

Short-pulsed UV lasers

provide fast and flex­ible

alternatives for creating

a wide range of 3D features.

Ultraviolet lasers excel in large area structuring and 3D micromachining. Advanced beam illumination and projection techniques allow for sharp-edged and uniform energy density distribution on target. This leads to fine control of the volume of material removed per pulse, enabling high-resolution machining and high-quality surface finish. Typical removal rates

 

are between 0.05 - 1.5 μm/pulse. When a single pattern must be repeated, the mask itself may contain an array of features, using the large beam cross section for simultaneously machining multiple features. By coordinating the motion of both mask and workpiece, large and complex patterns can be created.
