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 optimal performance and superior durability of high-tech electronic devices.

In the context of increasingly stringent requirements for microstructures and nanometer precision, deposition technologies such as CVD, PVD, and ALD have become indispensable solutions for leading semiconductor manufacturers:


  • CVD (Chemical Vapor Deposition): Chemical vapor deposition, enabling uniform, precise thin coatings over large areas, optimized for producing microprocessors and electronic sensors.

  • PVD (Physical Vapor Deposition): Physical vapor deposition, ideal for creating conductive metal layers and critical protective layers in microchips, ensuring conductivity and corrosion resistance.

  • ALD (Atomic Layer Deposition): Atomic layer deposition, delivering ultra-thin and absolutely uniform thicknesses, meeting the production needs of AI processors and ultra-small IoT devices.


With extensive experience and strong supply capabilities, Loc Thien Investment and Development Co., Ltd. is committed to providing deposition chemicals as well as semiconductor chemicals that meet international standards, helping optimize production processes and enhance semiconductor component quality.

Key Deposition Chemicals in the Semiconductor Industry

1. Silane (SiH₄)

  • Application: Primary silicon source in CVD, forming crystalline or amorphous silicon layers on silicon wafers.
  • Properties: Flammable upon contact with air, requiring storage in sealed and safe conditions.

2. Pure Ammonia (NH₃)

  • Application: Forms silicon nitride (Si₃N₄) in CVD, improving insulation and mechanical strength.
  • Note: Pungent gas, requiring good ventilation during use.

3. Hydrochloric Acid (HCl)

  • Application: Cleans and etches silicon wafer surfaces, removing metal impurities before deposition.
  • Note: Highly corrosive, store in non-metallic containers.

4. PVD Metals (Al, Ti, Au)

  • Aluminum (Al): Used as conductive wires in microchips.
  • Titanium (Ti): Adhesion and surface protection layers.
  • Gold (Au): High-end conductive layer, anti-oxidation and surface protection.

5. Tetraethyl Orthosilicate (TEOS)

  • Application: Liquid silicon source in CVD, forming thin, uniform, and precise silicon oxide (SiO₂) layers.

6. Trimethylaluminum (TMA)

  • Application: Precursor in ALD, forming aluminum oxide (Al₂O₃) layers with high durability, insulation, and heat dissipation.

7. Titanium Tetrachloride (TiCl₄)

  • Application: Forms titanium nitride (TiN) and titanium dioxide (TiO₂), reducing resistance and enhancing wear resistance.

Applications of Deposition Chemicals in the Semiconductor Industry

1. Creating Precise Thin Films

  • Forms SiO₂, Si₃N₄, TiN layers with high uniformity on wafer surfaces.
  • Ensures precise thickness and optimization for microstructures in IC, semiconductor chip, and NAND memory production.

2. Enhancing Electrical and Mechanical Performance

  • Reducing resistance: Optimizes conductivity and reduces energy loss.
  • Increasing mechanical strength: Protects microchips from physical impacts and pressure during production.

3. Protection and Insulation

  • Coatings such as Al₂O₃ and Si₃N₄ reduce signal noise and enhance insulation between conductive paths.
  • Anti-oxidation and corrosion protection, safeguarding components in harsh environments.

4. Optimizing Production Processes

  • Technologies like CVD and ALD accelerate production efficiency, meeting automated production lines in the semiconductor industry.

5. Heat Dissipation and Thermal Stability

  • Metal oxide layers such as Al₂O₃ and TiN effectively dissipate heat, extending the lifespan of central processing units (CPUs) and GPU graphics cards.

6. Applications in Ultra-Small Technology

  • Meets nanoscale microstructure requirements in AI processing chips, IoT devices, and 3D NAND memory.

Safety Usage Guidelines

  • Storage: Store chemicals in dry, cool places, avoiding direct exposure to heat and sunlight.
