Abstract: A magnetoresistive random access memory (MRAM) structure, including a substrate and multiple MRAM cells on the substrate, wherein the MRAM cells are arranged in a memory region adjacent to a logic region. An ultra low-k (ULK) layer covers the MRAM cells, wherein the surface portion of ultra low-k layer is doped with fluorine, and dents are formed on the surface of ultra low-k layer at the boundaries between the memory region and the logic region.

Abstract: A liquid-filled ornament includes a body having a transparent casing having an opening and filled with liquid, a display object in the liquid, and a sealing wall extending across and sealing the opening. The ornament includes a driving mechanism having rotatable magnets and located on an outer side of the sealing wall, and a driven mechanism having rotatable magnets and located on an inner side of the sealing wall and immersed in the liquid. The magnets of the driven mechanism are rotated by the magnets of the driving mechanism through magnetic interaction. The driven mechanism includes a first stationary disc on which the display object is mounted and a second disc supported on the first disc and rotated by the magnetic interaction. A ball bearing is disposed between the two discs. The second disc includes paddles that stir bits of a solid material, resembling snow, dispersing the bits throughout the liquid.
