Wafers are formed of highly pure, nearly defect-free single crystalline material, with a purity of 99.9999999% or higher. One process for forming crystalline wafers is known as Czochralski growth invented by the Polish chemist Jan Czochralski.In this process, a cylindrical ingot of high purity monocrystalline semiconductor, such as silicon or germanium, called a boule, is formed by pulling a

Investigations of oxygen precipitates in Czochralski

Currently, oxygen atoms are intentionally introduced in Si crystals during Czochralski (CZ) pulling process. They usually come from a controlled out-diffusion from the crucible, the expected role of these impurities being to generate silicon oxide clusters or micro-precipitates.
