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 digital camera includes a camera housing, an auxiliary lens, and an attaching device for attaching various additional or auxiliary lenses to the camera housing, and preferably disposed in front of the optical device of the digital camera, to facilitate the picture taking of the digital camera. The attaching device includes a bracket having a base plate attachable to the camera housing and a panel extended from the base plate to support the auxiliary lens. One or more barrels may further be attached to the panel, to support various auxiliary lenses to the camera housing. A fastener may secure the base plate to the camera housing, and may be attached to tripods.
