What it is
General reference — not yet source-verifiedA chemical vapor deposition system is a deposition tool used in semiconductor manufacturing to form thin films on wafer surfaces. Deposition tools of this class are used to create functional layers that become part of device structures or serve as insulating, protective, or pattern transfer films.
How it works
General reference — not yet source-verifiedChemical vapor deposition tools introduce process gases into a controlled chamber and use heat to drive chemical reactions that leave a solid film on the wafer surface. Low pressure chemical vapor deposition tools operate under reduced pressure to promote uniform film formation and controlled reactions across the wafer.
Where it fits in the process flow
General reference — not yet source-verifiedDeposition equipment sits in the thin film formation portion of the semiconductor process flow. Chemical vapor deposition commonly follows wafer preparation and precedes steps such as photolithography, etch, implant masking, or metallization, depending on the layer being formed.
Applications
General reference — not yet source-verifiedChemical vapor deposition systems are used to deposit films that act as dielectrics, barriers, passivation layers, or structural layers in integrated device fabrication. Deposition tools of this class also support film formation for patterning sequences in which a deposited layer is later etched or used to isolate underlying features.
