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: An electrical multi-functional fitness and body slimming massage device, particularly to functions relative to breast enhancement/skin care massage device, fitness/body slimming massage belt and electrical cupping developed on the basis of the air suction/release principle. The present invention has a housing and a plurality of suction cups with various sizes is disposed at the front end of the housing. Each suction cup has an air hole corresponding to air hole of the housing, with hoses disposed inside an air chamber. A gear/cam control box is disposed in the air chamber. One of the hoses connects to the cam structure, which presses and releases the hose to form a turbulent flow and control the suction/release in a fixed rhythm. A control valve is disposed outside the housing, with which the user can select suction only or release only function.
