  • Silicon Manufacturing | The Silicon Manufacturing Process

    17/07/2018· Silicon metal is made from the reaction of silica and carbon materials like coke, coal and wood chips. When it comes to the manufacturing of silicon for wafers, the process can generally be broken down into three steps. Those steps are reduction, cooling, and packaging. Let’s take a deeper look at the three main steps used in silicon manufacturing.Онлайн-запрос
