A. Wafer Fabrication

• Silicon Ingot Growth – Pure silicon is melted and grown into a cylindrical ingot using the Czochralski process.
• Wafer Slicing & Polishing – The ingot is sliced into thin wafers and polished to create a smooth surface.

B. Chip Manufacturing

• Photolithography – A pattern is transferred onto the wafer using a light-sensitive material and ultraviolet (UV) light.
• Etching – Unwanted material is removed using chemical or plasma etching.
• Doping (Ion Implantation) – Adding impurities to modify electrical properties.
• Deposition & Metallization – Layers of materials (like metal and dielectric) are deposited to form transistors and circuits.
• Chemical Mechanical Polishing (CMP) – Ensures a smooth and even wafer surface.

C. Packaging & Testing

• Die Cutting & Packaging – Individual chips are cut from the wafer, tested, and packaged for use in electronics.
• Final Testing & Quality Control – Ensures chips function correctly before shipment.

2. Semiconductor Materials

The most common materials used in semiconductor manufacturing include:

v  Silicon (Si) – The most widely used material due to its abundance and excellent semiconductor properties.

v  Gallium Arsenide (GaAs) – Used in high-speed and high-frequency applications like satellites and mobile networks.
