What it is
The ASM A 412 LPCVD Furnace is a low pressure chemical vapor deposition furnace used in semiconductor manufacturing.[1]
How it works
General reference — not yet source-verifiedAn LPCVD furnace deposits thin films by exposing heated wafers to process gases at reduced pressure inside a controlled reaction chamber. The reduced pressure helps regulate gas transport and film formation across the wafer load.
A furnace of this class generally processes multiple wafers together in a batch configuration. The thermal environment drives the chemical reaction that forms the deposited layer on the wafer surfaces.
Where it fits in the process flow
General reference — not yet source-verifiedAn LPCVD furnace sits in the deposition portion of the wafer fabrication flow. The machine adds film layers after earlier wafer preparation steps and before later patterning or further thermal processing steps that use the deposited film.
