Production Of Silicon Chips
Beginning of paper
Inside every modern computer or other data-processing wonder is a microprocessor bearing millions of transistors sculpted from silicon y
chemicals and light. Silicon, the second most abundant element on
Earth, is used extensively in transistors, integrated circuits, photoelectric devices, and othe ....

.... silicon chip starts when silica, the main component of sand, is heated with carbon which makes 98 percent pure silicon. This is then dissolved in hydrochloric acid. The resulting liquid is fractionally distilled to separate almost all of the impurities.The remaining liquid is then heated in a hydrogen tmosphere, which produces the purest silicon possible. This silicon, however, is in the form of many crystals of different sizes and orientations. This silicon goes through the Czochralski pulle ....
