Archer Materials has had its advanced graphene field effect transistor (“gFET”) chip design validated by a commercial foundry partner in the Netherlands with a whole four-inch wafer run.
The new advanced gFET device designs have been fabricated and the whole wafer run foundry process was reportedly successful. The electronic and spectroscopic characteristics of the gFET chips, and the foundry fabrication process yield, are said to be consistent with what Archer expected. The gFET chips are also compatible with Archer’s biochip system platform.
The advanced gFET design could create the potential for an early biochip platform that has single-device multiplexing, meaning the biochip technology would be able to sense different liquid samples to test for multiple diseases at once.
Archer now intends to integrate more functionality on the biochip, and optimize the device size and geometry to build advanced
sensing regions.
Commenting on the validation of the advanced gFET design, Dr Mohammad Choucair, CEO of Archer, said: “Archer’s biochip graphene sensor technology has essentially undergone translation from design to scalable semiconductor processing in a commercial foundry, which is both a key technology development and commercial milestone.... The whole wafer fabrication of the gFET device design is a significant step towards industrial
production. Archer is continuing to strengthen its relationships with global foundry partners to deliver these chips using a streamlined ‘fabless’ commercialization model.”
