Tantalum capacitor is an electronic component composed of tantalum metal and tantalum oxide, used for storing and releasing charges. It is a type of capacitor that stores charges internally based on the electric field effect and can release charges when needed.

Tantalum capacitors are composed of three main parts: tantalum film, oxide layer, and electrode. Tantalum thin films are prepared on substrates by Physical vapor deposition or chemical vapor deposition. Then, an insulating oxide layer, usually tantalum pentaoxide (Ta2O5), is formed on the surface of the tantalum film. The oxide layer can be formed by thermal oxidation, electrochemical oxidation or Physical vapor deposition. Finally, electrodes are formed on both sides of the oxide layer, typically using metals or alloys such as tantalum and tantalum nitrogen alloys.

The manufacturing process of tantalum capacitors involves the following Committed step:

1. Preparation of tantalum film: First, a thin tantalum film is deposited on the substrate by Physical vapor deposition (PVD) or chemical vapor deposition (CVD). This step needs to be carried out under vacuum or a specific atmosphere to ensure the obtaining of high-quality tantalum films.

2. Formation of oxide layer: An insulating oxide layer, usually tantalum pentaoxide (Ta2O5), is formed on the surface of tantalum metal films. The formation of this oxide layer is usually completed by thermal oxidation, electrochemical oxidation or Physical vapor deposition. The thickness and quality of the oxide layer are crucial for the performance of capacitors.

3. Formation of electrodes: Electrodes are made on both sides of the oxide layer, usually using metals or alloys (such as tantalum and tantalum nitrogen alloys). Electrodes are formed through physical coating, evaporation, or other metal deposition techniques to ensure good contact with tantalum thin films and oxide layers.

4. Packaging and connection: Tantalum capacitors usually need to be packaged to protect internal components and connected to the circuit through leads or soldering. This can be achieved by placing the capacitor in a protective shell and connecting it to the circuit board through leads or pads.
