Definition
A chemical vapor deposition reactor meters precursor gases into a controlled chamber where thermal energy, plasma, or both drive surface reactions that form dielectric, semiconductor, or conductive films with specified thickness and material properties.
Process position
Inputs
- Prepared wafer
- Precursor gases
- Carrier and reactant gases
- Deposition recipe
Outputs
- Deposited film
- Chamber and endpoint data
- Qualified wafer lot
How it works
- 01Prepare and stabilize chamber
- 02Load and heat wafer
- 03Introduce precursors and reactants
- 04Grow film to target
- 05Purge, cool, and unload
Role in the production flow
CVD spans many reactor modes and film families, so the equipment class should not be read as one interchangeable process. Chamber geometry, activation method, precursor chemistry, and wafer thermal history jointly determine film behavior.
A thermal or plasma-assisted reactor that forms solid films on wafers through controlled chemical reactions of vapor-phase precursors.
Boundary: The cited manufacturers document the equipment category and its intended uses; this record does not independently validate vendor performance claims or rank products.
Qualification and production boundaries
Qualification requires the named film composition, thickness, conformality, interface, thermal budget, stress, impurity limit, wafer size, throughput, chamber clean, and facilities and abatement envelope.
Qualification requires the named film composition, thickness, conformality, interface, thermal budget, stress, impurity limit, wafer size, throughput, chamber clean, and facilities and abatement envelope.
Boundary: Actual acceptance limits, recipes, throughput, availability, and ownership economics are product-, process-, site-, and contract-specific.
