Intermolecular Announces Breakthrough Four-Element ALD Chalcogenide-based OTS for 3D Memory Arrays

  • Atomic layer deposition (ALD) GeAsSeTe Ovonic Threshold Switch (OTS) device advances applications of 3D Non-volatile memory (NVM)
  • Enables new innovations in Neuromorphic Computing, AI, Gaming and Data Centers

 San Jose, Calif., June 16, 2020 – Intermolecular, Inc. (“Intermolecular”), the trusted partner for materials innovation and a wholly-owned subsidiary of Merck KGaA, Darmstadt, Germany, today announced the industry’s first quaternary atomic layer deposition (ALD) GeAsSeTe[1] OTS device for 3D vertical memory arrays. This breakthrough combination of materials will enable a 3D vertical NVM memory architecture for customers to design chips for high density, high performance computing applications at affordable costs.

“The Intermolecular team has deep expertise in testing, evaluating and discovering materials and innovating devices to solve leading edge customer problems,” said Casper van Oosten, Managing Director, Intermolecular. “Until now, building non-volatile memory in a high-density 3D architecture has been challenging because of the inability to stack tens of layers in a 3D structure, limiting memory density and consequently increasing the cost. This new material combination allows realization of these architectures, paving the way for neuromorphic computing, AI and other new semiconductor designs that are needed for faster and more affordable digital applications, from gaming to data centers.”
