  • INTEGRATED CIRCUITS WITH MEMORY CELLS AND METHODS FOR PRODUCING THE SAME
    Publication number: 20200194498
    Abstract: Integrated circuits and methods of producing the same are provided. In an exemplary embodiment, a method of producing an integrated circuit includes forming a lower contact in a lower interlayer dielectric layer. A base contact layer is formed overlying the lower interlayer dielectric layer and the lower contact, and a base contact is formed by removing a portion of the base contact layer. The base contact is formed in electrical communication with the lower contact. A base interlayer dielectric layer is formed overlying the lower interlayer dielectric layer after forming the base contact, where the base interlayer dielectric layer is adjacent to a base contact side surface. A memory cell is formed overlying the base contact, where the memory cell is in electrical communication with the base contact.
