Mesoline’s micro-channel particle deposition (MPD) offers a completely new way to create microstructures using nanoparticles to enable next-generation semiconductor devices.


Mesoline’s revolutionary micro-channel particle deposition (MPD) technology represents a completely new way of creating microstructures using nanoparticles. By harnessing microfluidics, our machines can build wafer-scale microstructures with unprecedented accuracy, in a matter of minutes. We offer our customers a unique platform which combines tooling and years of expertise in MPD. This allows customers to create new devices incorporating nanoparticle based functional elements and metal layers 

Step 1 - Placing the mold

A microstructured stamp is aligned to the wafer and carefully brought in contact by the Mesoline production tool.  
+ 4” up to 8” wafer capability.
+ Wafer scale printing capabilities.
+ Client tailored feature layout and design.

Step 2 - Filling the mold

Nano ink is injected into the stamp, filling the microstructures within it. With our in-house developed process unique nano materials can be printed:
+ Metals
+ Ceramics
+ Multi-material

Step 3 - Creating free-standing structures

The stamp is removed to reveal free-standing microstructures built-up from nanoparticles.  
+ Micron resolution
+ Nanometer form accuracy
+ Complex structures: e.g. High aspect ratio or Unique shapes.
