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: The invention discloses a dried glyphosate granule herbicide composition, comprising 50˜950 g/kg glyphosate, 5˜950 g/kg non-inorganic salt extender, and 0.5˜150 g/kg organo-silicon surfactant. The herbicide according to the present invention uses glyphosate as the active ingredient without turning it into salt derivatives, hence reducing the cost of preparation. The present invention also provides a method for preparing the glyphosate herbicide disclosed.
