Wafer fabrication is a procedure composed of many repeated sequential processes to produce complete electrical or photonic circuits on semiconductor wafers in a semiconductor device fabrication process. Examples include production of radio frequency (RF) amplifiers, LEDs, optical computer components, and microprocessors for computers.

In electronics, a wafer (also called a slice or substrate) [1] is a thin slice of semiconductor, such as a crystalline silicon (c-Si, silicium), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as the substrate for microelectronic devices built in and upon

2015年4月22日 · Building an ingot, the foundation for wafers. Once silicon is extracted from sand, it needs to be purified before it can be put to use. First, it is heated until it melts into a high-purity liquid then solidified into a silicon rod, or ingot, using common growing methods like the Czochralski (chokh-RAL-skee) process or the Floating Zone process.

2025年1月24日 · The wafer fabrication process is a complex, high-precision journey that transforms raw materials into the foundation for today’s most advanced technology. From slicing and polishing to doping and etching, each step must be performed with exacting standards to ensure the wafers are of the highest quality.

2025年1月6日 · Learn about the essential semiconductor manufacturing process – wafer manufacturing, oxidation, photolithography, etching, deposition and ion implementation, metal wiring, Eds and packaging.

2023年10月4日 · Let’s discuss six critical semiconductor manufacturing steps: deposition, photoresist, lithography, etch, ionization and packaging. The process begins with a silicon wafer. Wafers are sliced from a salami-shaped bar of 99.99% pure silicon (known as an 'ingot') and polished to extreme smoothness.

2025年1月11日 · The key steps in silicon wafer fabrication include crystal growth, wafer slicing, surface polishing, doping, and thin film deposition. What is the diameter of a standard silicon wafer? The standard diameter for silicon wafers used in the semiconductor industry is 300mm (12 inches), though smaller sizes such as 200mm (8 inches) are also common.
