The Semiconductor Wafer Manufacturing Process
Before diving into the market dynamics, it is essential to understand the manufacturing process of semiconductor wafers. Semiconductor wafers are typically made from crystalline silicon, which is sourced from silicon ingots. The manufacturing process can be summarized as follows:
- Ingot Growth: High-purity silicon is melted and then slowly cooled to form a single crystal structure known as an ingot.
- Wafer Slicing: The ingot is sliced into thin, circular wafers using diamond saws or wire saws. These wafers are extremely thin, typically less than 1 millimeter thick.
- Wafer Polishing: The sliced wafers undergo a chemical-mechanical polishing (CMP) process to achieve a mirror-like surface finish and a consistent thickness.
- Dopant and Epitaxial Growth: Depending on the application, dopants (such as boron or phosphorus) may be introduced to alter the wafer’s electrical properties. Epitaxial growth can also be used to deposit thin layers of specific materials on the wafer’s surface.
- Photolithography and Etching: Patterns are created on the wafer’s surface using photolithography, and then selective etching is applied to remove unwanted material.
- Ion Implantation: To precisely control the electrical characteristics of transistors and other components, ion implantation is used to introduce specific ions into the wafer.
- Metallization: Metal layers are deposited and patterned on the wafer to connect various components.
- Testing and Packaging: The individual chips on the wafer are tested, and then they are separated and packaged into integrated circuits.
