    摘要： Methods of manufacturing a magnetic memory device including forming a lower magnetic layer, a tunnel barrier layer, and an upper magnetic layer on a substrate, forming a magnetic tunnel junction (MTJ) pattern by patterning the lower magnetic layer, the tunnel barrier layer, and the upper magnetic layer, forming a first insulating layer exposing an upper surface of the MTJ pattern, forming a polymer pattern on the exposed upper surface of the MTJ pattern, forming a second insulating layer exposing an upper surface of the polymer pattern, removing the polymer pattern to form a cavity in the second insulating layer, the cavity exposing the upper surface of the MTJ pattern, and forming a metal line by filling the cavity with a conductive metal.

    摘要： Provided is a bend-insensitive optical fiber including a core centered at the optical fiber, a cladding surrounding the core and having a lower refractive index than the core, a coating layer surrounding the cladding, and a region formed in the cladding and having a lower refractive index than the cladding, wherein the coating layer has a multilayered structure and a total outer diameter of 240 μm or less, and a bend-insensitive optical cable comprising the same.
