Abstract: A semiconductor device includes: a substrate comprising a magnetic tunneling junction (MTJ) region and a logic region, a MTJ on the MTJ region, a top electrode on the MTJ, a connecting structure on the top electrode, and a first metal interconnection on the logic region. Preferably, the first metal interconnection includes a via conductor on the substrate and a trench conductor, in which a bottom surface of the trench conductor is lower than a bottom surface of the connecting structure.

Abstract: A semiconductor device includes a magnetic tunneling junction (MTJ) on a substrate, in which the MTJ includes a pinned layer on the substrate, a reference layer on the pinned layer, a barrier layer on the reference layer, and a free layer on the barrier layer. Preferably, the free layer and the barrier layer have same width and the barrier layer and the reference layer have different widths.

Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A brush roller and its manufacturing method and brush roller mold is provided, the brush roller is manufactured by foaming a gaseous pore filler, while solving the problem of using a solid pore filler foaming method to manufacture the brush roller. In addition, the brush roller of the present invention has a plurality of fluid channels communicating between any adjacent two, and the plurality of fluid channels respectively extend to the surface of the brush roller to form pores to improve the fluid permeability of the brush roller, and in the brush roller manufacturing method of the present invention, after the PVA emulsified solution is cured, the compressive stress under the condition of the predetermined compression ratio can be formed to meet the expected brush roller, and it can be used to brush the circuit substrate.
