TL;DR: In this paper, the authors proposed an approach to provide a semiconductor device in which a ZnO and aluminium is used as the material of electrode and interconnect line, and an insulating protective layer 7 located between the lower surface of the semiconductor layer 4 and the side face of the first conductive layer 2.
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device in which a semiconductor layer is formed of ZnO and aluminium is used as the material of electrode and interconnect line SOLUTION: The semiconductor device comprises a substrate 1, at least one electrode supported by the substrate 1, and a semiconductor layer (ZnO) 4 touching the upper surface of the electrode at least partially The electrode comprises a first conductive layer 2 of aluminium, a second conductive layer 3 formed of a material (Ti, or the like) causing less electrolytic corrosion reaction than aluminium between the upper surface of the first conductive layer 2 and the semiconductor layer 4, and an insulating protective layer 7 located between the lower surface of the semiconductor layer 4 and the side face of the first conductive layer 2 COPYRIGHT: (C)2004,JPO&NCIPI

TL;DR: A comprehensive body of knowledge has built up with respect to the friction stir welding (FSW) of aluminium alloys since the technique was invented in 1991 is reviewed in this article, including thermal history and metal flow, before discussing how process parameters affect the weld microstructure and the likelihood of entraining defects.
Abstract: The comprehensive body of knowledge that has built up with respect to the friction stir welding (FSW) of aluminium alloys since the technique was invented in 1991 is reviewed The basic principles of FSW are described, including thermal history and metal flow, before discussing how process parameters affect the weld microstructure and the likelihood of entraining defects After introducing the characteristic macroscopic features, the microstructural development and related distribution of hardness are reviewed in some detail for the two classes of wrought aluminium alloy (non-heat-treatable and heat-treatable) Finally, the range of mechanical properties that can be achieved is discussed, including consideration of residual stress, fracture, fatigue and corrosion It is demonstrated that FSW of aluminium is becoming an increasingly mature technology with numerous commercial applications In spite of this, much remains to be learned about the process and opportunities for further research a
