Discover all the specifications
Also, these manual processes increase the risk of wafer breakage and result in efficiency losses.
Current cleaning methods, like ultrasonic baths and repeated validations, do not always remove all residues, which lead to QA inspection rejections.
Why our dry laser cleaning solution is better?
Benefits of our solutions
- Time-saving
- Productivity improvement
- Process automation
- Efficient and accurate process
Advantages of our solutions
- Robust software integration in DMC
- Quickly integrates through partners such as Ficontech or Jaybil.
- Less manipulation which reduce QA inspection rejections
- On-site installation, reducing part handling.
- 2.8um enables selective removal of organic residues while
preserving the substrate.
Why our laser trimming solution is better?
Current methods do not simultaneously achieve strong phase shift, low loss and fast time-to-market.
With Femtum, you can improve your manufacturing process for better production efficiency.
