Deposition tools add thin films onto wafers as part of device fabrication. Chemical vapor deposition systems generally form films by introducing reactive process gases into a controlled chamber so material deposits onto the wafer surface.

Chemical vapor deposition systems generally operate by exposing wafers to precursor gases under controlled thermal and pressure conditions so a solid film forms on the wafer. Semiconductor deposition platforms of this class commonly integrate wafer handling with one or more process chambers to carry out repeatable thin-film formation.

Deposition tools sit in the film-formation portions of wafer fabrication, where they build layers used for isolation, dielectric formation, passivation, barrier functions, or other stack elements. Deposition steps are commonly coordinated with lithography, etch, clean, and thermal processes because deposited films are often patterned or used as underlying layers for later pattern transfer.

Chemical vapor deposition tools are used wherever a semiconductor process needs a conformal or controlled thin film rather than bulk material removal or implant. Such tools commonly support formation of insulating, protective, or functional layers within integrated device structures.
