  • Publication number: 20240247090
    Abstract: Synthesis of imidazolium-based poly(ionic liquid)s is disclosed. Chemical Mechanical Planarization (CMP) slurries comprise abrasives; activator; oxidizing agent; additive comprising imidazolium-based poly(ionic liquid); and water. The use of the synthesized imidazolium-based poly(ionic liquid)s in the CMP slurries reduces dishing and erosion in highly selective tungsten slurries.

  • Patent number: 12046269
    Abstract: A two-bit memory device having a layer structure containing in order a bottom layer, a molecular layer containing a chiral compound having at least one polar functional group, and a top layer, which is electrically conductive and ferromagnetic. The chiral compound acts as a spin filter for electrons passing through the molecular layer. The chiral compound is of flexible conformation and has a conformation-flexible molecular dipole moment. An electrical resistance of the layer structure for an electrical current running from the bottom layer to the top layer has at least four distinct states which depend on the magnetization of the top layer and on the orientation of the conformation-flexible dipole moment of the chiral compound. Furthermore, a method for operating the two-bit memory device and an electronic component containing at least one two-bit memory device.
