From Sand to Processor or How a CPU is made - Intel

It is hard to believe that a modern processor (CPU) is the most complex product in the world. What is so complex in this piece of metal? In this article I will try to explain how a modern processer (CPU) is made from the sand. Processor Manufacturing It takes about $ 5 billion dollars to build a processor manufacturing factory. The process of processor manufacturing looks like this: the special equipment is used to grow a mono-crystal of cylindrical shape from the molten silicon. Some Chemistry Lessons Let us take a closer look at the whole process of manufacturing. Originally, it is taken in the form of SiO2 sand, which is in arc furnaces (at the temperature about 1800 ° C) reduced by coke: SiO2 + 2C = Si + 2CO This silicon is called a "technical" and has a purity of 98-99.9%. 3SiCl4 + 2H2 + Si ↔ 4SiHCl3 These recycling reactions that are generated by side silicon-contained materials reduce the cost and eliminate the environmental problems: Photolithography Photo Resist Application Etching

Computer Science | Video Courses on Academic Earth In its purest form, computer science is the research and development of technology that solves specific problems. Computer science has brought the world smart phones, GPS systems, the gaming industry and tablet computing, along with technological developments that assist government, industry and medicine. In addition to creating new technology, computer scientists also make improvements to existing technology and study the ways computers can make our lives easier. As with any branch of science, computer scientists perform research that establishes new information. Exploring fundamental questions about computation is the first step toward designing the hardware, software and complex network systems that we rely upon. Sample Courses During the first two years of a standard 4-year program, students focus on the basics: Calculus I, II, & IIIProgram DesignFoundations of ComputingData StructureIntroduction to AlgorithmsComputer ArchitectureInformation RetrievalComputer Graphics Degree Types Ph.D.
