Overview of Precipitation Chemicals in the Semiconductor Industry

Overview of Deposition Chemicals in the Semiconductor Industry

Deposition chemicals are a core element in the manufacturing process of modern semiconductor components, contributing to the creation of ultra-thin, precise coatings on silicon wafers—the foundation for ensuring optimal performance and superior durability in high-tech electronic devices.

Against the backdrop of increasingly stringent requirements for microstructures and nanometer-level precision, deposition technologies such as CVD, PVD, and ALD are becoming indispensable solutions for leading semiconductor manufacturers:

  • CVD (Chemical Vapor Deposition): Chemical vapor deposition enables the creation of uniform, precisely thin coatings over large areas, making it ideal for the production of microprocessor chips and electronic sensors.
  • PVD (Physical Vapor Deposition): Physical vapor deposition is ideal for creating conductive metal coatings and critical protective layers in microchips, ensuring electrical conductivity and corrosion resistance.
  • ALD (Atomic Layer Deposition): Atomic layer deposition, delivering ultra-thin layers with absolute uniformity, meeting the production needs of AI processors and ultra-small IoT devices.

Key Deposition Chemicals in the Semiconductor Industry

1. Silane (SiH₄)

  • Applications: The primary source of silicon in CVD, used to form crystalline or amorphous silicon layers on silicon wafers.
  • Properties: Highly flammable when exposed to air; requires storage in sealed and secure conditions.

2. Pure Ammonia (NH₃)

  • Applications: Forms a silicon nitride (Si₃N₄) layer in CVD, helping to improve electrical insulation and mechanical strength.
  • Note: The gas has a pungent odor; adequate ventilation is required during use.

3. Hydrochloric Acid (HCl)

  • Applications: Cleaning and etching silicon wafer surfaces, removing metal impurities prior to deposition.
  • Note: Highly corrosive; store in a container.
Non-metallic.

4. PVD Metals (Al, Ti, Au)

  • Aluminum (Al): Used as conductors in microchips.
  • Titanium (Ti): Adhesive and surface protection layer.
  • Gold (Au): A high-performance conductive layer that provides oxidation resistance and surface protection.

5. Tetraethyl Orthosilicate (TEOS)

  • Applications: A source of liquid silicon in CVD, used to form thin, uniform, and precise silicon oxide (SiO₂) layers.

6. Trimethylaluminum (TMA)

  • Applications: Precursor in ALD, forming an aluminum oxide (Al₂O₃) film with high durability, excellent electrical insulation, and effective heat dissipation.

7. Titanium Tetrachloride (TiCl₄)

  • Applications: Deposits titanium nitride (TiN) and titanium dioxide (TiO₂) layers, helping to reduce electrical resistance and enhance wear resistance.

Applications of Deposition Chemicals in the Semiconductor Industry
