The source of Energy
A summary of the physical and chemical nature of life must begin, not on the Earth, but in the Sun; in fact, at the Sun몶s very center. It is here that is to be found the source of the energy that the Sun constantly pours out into space as light and heat. This energy is librated at the center of the Sun as billions upon billions of nuclei of hydrogen atoms collide with each
The Advantages and Disadvantages of the Nuclear power
Nuclear power plants provide about 17 percent of the worlds electricity. Some countries depend more on nuclear power for electricity than others. In France, for instance, about 75 percent of the electricity is generated from nuclear power. There are more than 400 nuclear power plants around the world.

3. Requirements of EUV resist
EUV is highly absorbed by all materials, even EUV optical components inside the lithography tool are susceptible to damage, mainly manifest as observable ablation. Such damage that is associated with the high-energy process of generating EUV radiation is a new concern specific to EUV lithography .
EUVL's shorter wavelength also increases flare, resulting in less
Examination of the microstructural image of a specimen magnified by a reflected light microscope from 50x to 1000x in air( or up to 2000x with oil immersion).
Features of metallurgical specimens such as grains, gbs, cracks, ppts can be distinguished because they differ in contrast, caused by the differences in (a) the amount of light absorbed and (b) the inclination of those atomic planes that
● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for
