Abstract: The present disclosure provides a semiconductor structure. The semiconductor structure includes an insulation layer. A bottom electrode via is disposed in the insulation layer. The bottom electrode via includes a conductive portion and a capping layer over the conductive portion. A barrier layer surrounds the bottom electrode via. A magnetic tunneling junction (MTJ) is disposed over the bottom electrode via.

Abstract: A method includes forming Magnetic Tunnel Junction (MTJ) stack layers, which includes depositing a bottom electrode layer; depositing a bottom magnetic electrode layer over the bottom electrode layer; depositing a tunnel barrier layer over the bottom magnetic electrode layer; depositing a top magnetic electrode layer over the tunnel barrier layer; and depositing a top electrode layer over the top magnetic electrode layer. The method further includes patterning the MTJ stack layers to form a MTJ; and performing a passivation process on a sidewall of the MTJ to form a protection layer. The passivation process includes reacting sidewall surface portions of the MTJ with a process gas comprising elements selected from the group consisting of oxygen, nitrogen, carbon, and combinations thereof.

Abstract: An antenna module includes a first antenna radiator including a feeding terminal, a second antenna radiator, a first ground radiator, a second ground radiator and a capacitive element. The second antenna radiator is disposed on one side of the first antenna radiator, and a first gap is formed between a main portion of the second antenna radiator and the first antenna radiator. The first ground radiator is disposed on another side of the first antenna radiator, and a second gap is formed between the first antenna radiator and the first antenna radiator. The second ground radiator is disposed between the second antenna radiator and the first ground radiator, and a third gap is formed between the second ground radiator and a first branch of the second antenna radiator. The capacitive element is disposed on the third gap and connects the second antenna radiator and the second ground radiator.

Abstract: A tripod head assembly having a tripod head joined with a handle by means of a coupler. The tripod head has a neck. The coupler has (a) a first member having a first end, a second end (b) a second member having a first end, a second end through which a passage is formed , a slit formed in the second end of the second member, thus forming a clamp through which a passage is formed and (c) a block with a passage wherein a number of teeth are formed, the block formed together with the second end of the second member. The first end of the first member is linked to the first end of the second member and the second end of the first member is linked to the block to form a hole for receiving the neck. The handle has a slender tip wherein a threading is formed and a number of teeth formed near the tip. A bolt has a shank and a slender tip on which a threading is formed. The tip of the bolt is insertable through the passage formed in the second end of the second member and the passage formed in the clamp.
