Abstract: A metal adhesion layer may be formed on a bottom and a sidewall of a trench prior to formation of a metal plug in the trench. A plasma may be used to modify the phase composition of the metal adhesion layer to increase adhesion between the metal adhesion layer and the metal plug. In particular, the plasma may cause a shift or transformation of the phase composition of the metal adhesion layer to cause the metal adhesion layer to be composed of a (111) dominant phase. The (111) dominant phase of the metal adhesion layer increases adhesion between the metal adhesion layer.

Abstract: A juice extractor with a brake protection device comprises a main body including a power cutting device and a brake protection device received therein. The power cutting device includes a motor with a driving shaft, and a blade disc is connected to the driving shaft. The brake protection device includes an operation member movably and pivotably connected to the main body, at least a spring connected to the main body, at least a brake frame pivotably connected to the main body, a micro-switch disposed inside the main body, and a brake disc connected to the driving shaft. The operation member has a push member which is coupled to the brake frame and the spring. When the operation member is moved downward and detached from a stopping portion disposed at a top portion of the main body, the push member is pressed downward to push the micro-switch in order to cut off the power for a motor.

Abstract: A juice extractor includes a main body including a cutting device and a brake device received therein. The cutting device includes a motor with a driving shaft and a blade disc is connected to the driving shaft. The brake device includes an operation member movably connected to the main body, a spring connected to the main body, a brake frame pivotably connected to the main body, and a brake disc connected to a driving shaft. The operation member has a push member which contacts the brake frame and the spring. When the operation member is moved downward, the push member releases a force applied to the brake frame and the spring, so that the brake frame applies a force to the brake disc to brake the juice extractor. When the operation member is moved upward, the push member applies a force to the brake frame and the spring, so that the brake frame releases a force applied to the brake disc.
