Silicon Wafer Manufacturers Semiconductor Chip ...

After the silicon is refined, it is then heated until it reaches a molten state. At that point, a perfectly structured silicon “seed” is then lowered into the molten silicon. When the process is complete, the finished ingot exactly mimics the physical characteristics of the original seed material. The ingot is then cut into thin wafers.
