A method of forming a metal wiring in a semiconductor device. In order to overcome the limitation of copper filling into the damascene pattern formed on an insulating film using copper as a metal wiring, a chemical enhancer layer is formed on the damascene pattern which is then filled with copper by depositing copper by means of MOCVD method using a copper precursor. The chemical enhancer is exposed to a plasma process or radical plasma process so that it remains only within a bottom portion of the damascene pattern. Therefore, a selective copper deposition within the damascene pattern is provided to accelerate the deposition speed of copper by CECVD method, thus overcoming the limitation of slow and incomplete copper filling for ultra-fine structures.

This invention discloses methods and apparatus for ultrasonic color imaging that characterizes ultra-fine structures and distributional physical conditions within the target under inspection. The disclosed complementarily incorporates information arising from a plurality of repeated sound trips forced by repeated reflections of exterior and interior interfaces of target, and expresses the information into an image segment representing the main path that ultrasonic signals traveled within the target. The image produced is substantially more discriminative, descriptive, and position-sensitive to both acoustic interfaces and distributional acoustic characteristics of the target. The invention is especially useful for thin sheet targets most vulnerable to both non-continuous and continuous interior defects. The continuous interior conditions and effects of ultra-thin layered structures, that traditional ultrasonic inspection has been unable to express, are effectively expressed by linking their effects of deforming the waveform of passing ultrasonic signals to color image details.

The device is suitable for the experiment research and teaching of a quantum physics specialty and used for testing and displaying the hyperfine structure energy level of the hydrogen atom. Pure hydrogen is ionized and then dissociated into the hydrogen atoms according to a quantum mechanics principle; each generated ground-state hydrogen atom is in four hyperfine structure energy states, namely |F=1, mF=+1)|F=1, mF=0)(high energy state) and |F=1, mF=-1)|F=0, mF=0)(low energy state), wherein F is the angular quantum number of the ground-state hydrogen atoms, and mF is a magnetic quantum number. The device is manufactured on the basis of a principle that the hydrogen atoms in the high energy states are focused towards a center and the hydrogen atoms in the lower energy states are deflected towards an edge after the ground-state hydrogen atoms pass through a magnetic field with a certain gradient and comprises a hydrogen source system, an ionization system, a tiny drainage hole collimator, a deflection magnet, an imaging target, a vacuum system, a distance adjusting device, a support frame, data acquisition and analysis software, and the like.
