cpu的生产制造过程（The manufacturing process of CPU）

cpu的生产制造过程（The manufacturing process of CPU） The manufacturing process of CPU Now on the market are rich, when you use a superb collection of beautiful things, equipped with the latest CPU computer group in the Internet, operate freely when in various applications, there is no interest to think this is not a small head, the function of CPU is how to make out. In the semiconductor manufacturing industry today, the CPU is affected by the field the highest degree of concern, and the big two as everyone knows in this field, which is followed by the processor architecture is x86, and the other is known as the information industry giant blue IBM, also have a processor capable of designing and manufacturing strong. They first invented the strained silicon technology, and manufacturing process in the forefront in the 90 nanometer processor. In this article, we will step by step for you about the central processor to the whole process of integrated circuit chip is a powerful from a pile of sand. The basic raw material for manufacturing CPU If asked about the material of CPU is what everyone will answer is an easy job to do si. This is not false, but silicon and from where? In fact the most obscure sand. It is difficult to imagine, expensive, complex structure, powerful, mysterious CPU from the root of the sand was not worth a hair. Of course, this is bound to experience a complex manufacturing process. But not just grab a handful of sand materials can do, must be carefully selected to extract the most pure silicon raw materials from it. Just imagine, if you use the most inexpensive and abundant raw materials made of CPU, then how will the quality of the finished products, you can use like this high performance processor? Remove silicon, CPU also need one kind of important material is metal. So far, aluminum has become the main parts of the metal material inside the processor, and the copper is gradually being phased out, this is some of the reasons, the working voltage of CP
