Monocrystalline silicon - Wikipedia
Monocrystalline silicon, often referred to as single-crystal silicon or simply mono-Si, is a critical material widely used in modern electronics and photovoltaics. As the foundation for silicon-based discrete components and integrated circuits, it plays a vital role in virtually all modern electronic equipment, from computers to smartphones.
Czochralski method - Wikipedia
The Czochralski method, also Czochralski technique or Czochralski process, is a method of crystal growth used to obtain single crystals of semiconductors (e.g. silicon, germanium and gallium arsenide), metals (e.g. palladium, platinum, silver, gold), salts and synthetic gemstones.
Monocrystalline pulling process | SUMCO CORPORATION
A seed crystal silicon rod is placed on the surface of the molten silicon in the crucible, and is pulled up while rotating it, to form a monocrystalline ingot having the same orientation of atoms as the seed crystal.
Boule (crystal) - Wikipedia
A boule of silicon is the starting material for most of the integrated circuits used today. In the semiconductor industry synthetic boules can be made by a number of methods, such as the Bridgman technique [2] and the Czochralski process, which result in a cylindrical rod of material.
Fabrication of the single crystal - Waferfabrication - Halbleiter
A seed crystal (a perfect single crystal) on a rotating rod is brought to the surface of the silicon melt. This seed crystal pretends the orientation of the silicon crystal. In contact with the seed crystal, the melt overtakes its crystal structure.
Single-Crystal Silicon: Growth and Properties | SpringerLink
Jan 1, 2017 · As the zone travels along the polysilicon rod, single-crystal silicon freezes at its end and grows as an extension of the seed crystal. After seeding, a thin neck about 2 or 3 mm in diameter and 10–20 mm long is formed.
Silicon Crystal Growth and Wafer Technologies - ResearchGate

Aug 1, 2021 · Czochralski (Cz) silicon single crystal growth process is a large delay, nonlinear dynamic time-varying system with complex physicochemical reactions, multi-field and multi-phase coupling, and its modeling and control has always been a problem in the automatic control field.
Modern Civilization Relies on This Crystal-Growing Method
Dec 6, 2019 · Once the silicon melted, he placed a small piece of polycrystalline material—a seed crystal—on the end of a 14-centimeter-long, rotating rod. He then slowly lowered the rod into the crucible until the seed crystal dipped just below the surface of the molten silicon.
Silicon Single Crystal - an overview | ScienceDirect Topics
Single crystal silicon is the most widely used semiconductor material as a substrate material due to its excellent machinability, mechanical stability, and the potential to combine sensing elements and electronics on the same substrate. Circular wafers made of silicon are used as substrate in most MEMS sensors.
