Metal Deposition in Semiconductor Fabrication

What Is Metal Deposition?

Metal deposition is a critical process in semiconductor fabrication that involves applying thin metal layers onto a substrate. These thin films form electrical connections, interconnects, and contacts, essential for advanced electronic devices.

Types of Metal Deposition Methods

• Physical Vapor Deposition (PVD): Includes sputtering and evaporation to deposit metals like aluminum and copper.
• Chemical Vapor Deposition (CVD): Deposits metals like tungsten and titanium nitride through gas-phase reactions.
• Electroplating: Uses a solution with metal ions and electric current to deposit thick metal layers.
• Atomic Layer Deposition (ALD): Deposits ultra-thin films one atomic layer at a time.

Applications in Semiconductor Fabrication

• Electrical Interconnects: Provides pathways for signal transmission using metals like copper and aluminum.
• Contact Layers: Establishes conductive interfaces between semiconductors and circuits.
• Barrier Layers: Prevents metal diffusion into sensitive areas using titanium nitride or tantalum.
• Reflective Coatings: Enhances optical efficiency in LEDs and photodetectors.
• Thermal Management: Dissipates heat using metals like gold and silver.

Advantages of Metal Deposition

• Precision: Enables nanometer-scale thin films.
• Versatility: Supports various metals for different applications.
• Scalability: Ideal for high-volume production.
• Integration: Seamlessly integrates with semiconductor processes.
