Abstract: A semiconductor device and a method of forming the same are provided. The method includes forming a bottom electrode layer over a substrate. A magnetic tunnel junction (MTJ) layers are formed over the bottom electrode layer. A top electrode layer is formed over the MTJ layers. The top electrode layer is patterned. After patterning the top electrode layer, one or more process cycles are performed on the MTJ layers and the bottom electrode layer. A patterned top electrode layer, patterned MTJ layers and a patterned bottom electrode layer form MTJ structures. Each of the one or more process cycles includes performing an etching process on the MTJ layers and the bottom electrode layer for a first duration and performing a magnetic treatment on the MTJ layers and the bottom electrode layer for a second duration.

Abstract: A coaxial mid-drive power device of a bicycle includes a reducing structure and a hollow shaft motor engaged with the reducing structure that are disposed in a motor base. An output end of the reducing structure is operatively coupled with a one-way bearing bracket with a sprocket base via a one-way bearing. A crank spindle engaged with the one-way bearing bracket through another one-way bearing penetrates through the motor base. The two one-way bearings respectively have opposite rotation directions and are respectively located on different sides, i.e., an inside and an outside, of the one-way bearing bracket. A strain gauge disposed on the crank spindle is electrically connected to an annular conductive rail assembly engaged with the crank spindle and an elastic sheet assembly on a control circuit board in the motor base, hence the strain gauge could directly obtain a change in a torque of the crank spindle.
