Ni silicide has been chosen as the material to use for advanced CMOS process because of its superior properties; its lower resistivity (~15μΩcm), lower thermal budget (low formation temperature, wide process window), smaller silicon consumption (as compared with both TiSi2 and CoSi2), and no line width dependence [1].

Moreover, the development of web-based instruction also created a good technological environment for the educational reform of public physical education theories in universities, which is now playing a crucial role for public physical education courses to propagate advanced physical fitness ideology to students, to develop and expand the splendid national sports culture, as well as to help students form the habit and concept of physical training all their lives.
Teaching Process of Web-based Basketball Instruction Information of courses Learning of courses Recourses of study Test online Selected case courses introduce Electric lesson plan Paper lesson plan teaching program Related data Teaching PPT Race video Book case Test questions Forum of study Prior to the experiment, a test was conducted in both the experimental class and the comparative class, with the purpose to investigate students’ basic physical fitness, the special physical fitness for basketball, as well as their interest in sports, so as to ensure that the two classes were of homogeneity, and to guarantee a higher reliability of this experiment.
By contrast, in web-based basketball instruction of public physical education, all students will browse with clear pertinence the standard and advanced video materials provided by teachers at the very beginning.

The Nano Carbide Control: Design of Super Ferrite in Steels Hung-Wei Yen1, a , Chi-Yuan Huang2, b and Jer-Ren Yang1, c 1 Dept. of Material Science and Engineering, National Taiwan University, Taipei, Taiwan 2 Steel and Aluminium Research and Development Dept., China Steel Co., Kaohsiung, Taiwan a b91507047@ntu.edu.tw, b148023@mail.csc.com.tw, cJRYang@ntu.edu.tw Keywords: Super ferrite, interphase precipitation, nanometer-sized carbide, low carbon steels.
It is clear that one of the most important factors in the development of this type of advanced HSLA steels is to obtain the optimum volume fraction of the nanometer-sized carbides by interphase precipitation before the carbide coarsening.
The features of the corresponding carbides are also examined by advanced TEM.

Investigation of processes evolving during thin film production by laser surface modification Boross, Péter1 ; Kálazi, Zoltán 1 ; Verezub, Olga 2 ; Verő, Balázs 1 1 Bay Zoltán Institute for Materials Science and Technology, Budapest, Hungary 2 University of Miskolc, Faculty of Materials and Metallurgical Engineering, Miskolc, Hungary Keywords: Laser surface modifications, Particle penetration, Equilibrium, Oscillation, Marangonieffect, Solubility, Abstract The usefulness of the laser surface modifications is considerably reduced by the fact that the preevaluation and reproduction of these processes are not sufficent.
To reach advance in these fields, we have to clarify the physical processes taking place during the treatment.
The convection may be of with high velocity (the forces occur are relatively large corresponding to the mass of the melt pool and to the mass of the flowing substance), so this flow can advance the penetration of a floating particle, or constrain the penetration of a particle accelerated by the carrier gas (in Fig. 4 we can see an imprint of a vortex of the Marangoni-flow). 11 Caused by the large temperature-dependence shown by the surface tension. 12 This is only the vertical direction, which occurs as force vector and movement direction in the penetration model in section 1.
