Ink Jet Area

Technical staff

Ink jet technology is used for direct writing on silicon or polymer substrates. Altadrop equipment allows for example zinc oxide nano particles for the realization of gas sensors or iron oxides nano particles with carbon nano-tubes for antennas manufacture. 
Activities in the inkjet area are : 

  • the synthesis of inks in LAAS or in collaboration with external research teams
  • the development of processes
  • the improvement of the equipment

Means of manufacturing 

Ink Jet 



Chemical wet bench




Viscosimeter ; Uv ozone treatment, granulometer 


Know How 

Know-how results from studies carried out in the three areas : 

  • Inks synthesis
  • Development of deposition processes
  • Equipment improvement

Photos below show deposits with different nano carbon tubes concentrations from a suspension in ethylene glycol. 

Deposition of carbon nano tubes 40µm width lines was: 
A : low concentration (5 runs) 

B: high concentration (10 runs)
