Changing the future of arsine supply for MOCVD

Arsine gas is an
industrial Pandora's Box.

Premissa is a provider of equipment and services for on-demand industrial specialty hydride gases--such as arsine--used for production of semiconductors, solar cells, LED’s and other energy creating and saving devices. Premissa uses a unique, patented electrochemical process which uses a refillable solid source cell to generate on-site and on-demand ultra-pure arsine at lower cost than compressed arsine cylinders. It can also automatically provide blended arsine/hydrogen mixtures, at the pressure needed, to your MOCVD reactor.

The Premissa arsine generator eliminates the hazards and community concerns about compressed arsine gas cylinders at your Fab:

  • No cylinder transportation to your plant
  • No cylinder storage or storage limitations
  • No cylinder change-outs

Premissa was founded to make production, distribution and handling of gases such as arsine and other toxic industrial hydrides:

  • Faster. On demand, onsite, always available 24/7.
  • Better. Highest purity (>99.9999%) at lower cost than arsine gas cylinders--without the hazards. Fully automated production, simple graphic interface to chose arsine delivery time, concentration, and pressure for your MOCVD run.
  • Safer. No cylinders, cylinder delivery, changeouts or storage.
  • Efficient. Low energy consumption. Electrochemical process--instant ON/OFF.
  • Scalable. Pallet size canister modules; 5 slpm, with up to 500 kg arsine delivery per module (that’s equal to 20 to 50 arsine gas cylinders!)
  • Easier, Lower Cost. Refillable canisters designed for continuous operation, shipped by common truck or air-freight

Based on over 25 years of prior experience with electrochemical industrial gas production, Premissa’s newly patented technology is the ONLY process providing industrial scale for on-site arsine gas generation.
