Monocrystalline ingot is grown from silicon using the Czochralski process. High-purity polysilicon is melted down in a quartz crucible. After adding a precise amount of dopant (boron or phosphorus), a seed crystal is dipped into the molten silicon. Pulling out the seed while rotating it allows the silicon to form a single crystal ingot, which can be grown from 1 up to 1.8 meters in length and 6 or 8 inches in diameter.

・Monocrystalline silicon ingots (dummy ingots for testing purposes)
・Multicrystalline silicon ingots (for sputtering)
