A 3D Integrated Universal Digital GATE

Patent Status: 

Patent Filed

Indian Patent Applicaton No: 



Single device structure to function as a Digital NOR (NAND) gate

Key Features: 

  • Utilization of amorphous organic layers which can be stacked to obtain a single device structure to work as universal NOR (NAND) Gate.
  • OR/AND Gate and INVERTER are combined together to get NOR/NAND Gate
  • OR/AND Gate is realized by modified diode logic while inverter by organic transistor with 3 electrodes.
  • Output electrode of OR/AND Gate and input electrode of inverter are merged into a single metal layer to get a single device working as NOR/NAND Gate.


  • Proposed NOR/NAND Gate fits into the area of an inverter only.
