đź”· Introduction
With the continuous miniaturization of devices in microelectronics, photonics, and biomedicine, precision fabrication has become more critical than ever. Traditional methods such as mechanical machining, wet/dry etching, and photolithography have long served as industry standards. However, as design complexity and material requirements evolve, these conventional processes reveal limitations in precision, flexibility, and material compatibility.
Femtosecond (fs) laser processing, powered by ultrashort pulses and extremely high peak intensities, presents a breakthrough in micro-nano manufacturing. It offers a unique, non-thermal, mask-free approach to fabricating intricate 2D and 3D structures across a wide range of materials—from metals and semiconductors to transparent dielectrics.
🟢 Key Differences: Fs-Laser vs. Traditional Techniques
| Aspect | Traditional Methods | Femtosecond Laser Processing |
|---|---|---|
| Heat Impact | High thermal damage, recast layers, heat-affected zones | Cold processing, negligible heat diffusion |
| Material Versatility | Limited to certain materials, requires coatings or masks | Works on metals, polymers, glasses, crystals—without pretreatment |
| Resolution | Typically micrometer scale | Sub-micron to nanoscale (down to ~100 nm) |
| Fabrication Complexity | Multi-step, mask-dependent, cleanroom-based | Direct writing, maskless, fast prototyping |
| 3D Capability | Limited, especially in transparent materials | True 3D microstructuring inside transparent substrates |
| Environmental Conditions | Often requires vacuum or chemicals | Air or controlled environments, minimal waste |
| Scalability | Optimized for high-volume replication | Suitable for rapid prototyping and high-mix, low-volume production |
