What it is
General reference — not yet source-verifiedEtch systems in semiconductor manufacturing are used to remove material from wafer surfaces in defined patterns, typically through plasma-based or reactive-gas processes. The Ulvac NE 5500 falls into this class of production equipment, serving the etch step of device fabrication.
How it works
General reference — not yet source-verifiedPlasma etch systems generally operate inside a vacuum chamber, where process gases are introduced and energized by radio-frequency power to form a plasma. The plasma generates reactive species that chemically attack exposed film layers, while energized ions can provide a physical component to the etch. Endpoint detection and pressure and flow control regulate etch depth and uniformity.
Where it fits in the process flow
General reference — not yet source-verifiedEtch tools are used in semiconductor manufacturing to transfer a photoresist pattern into an underlying film, such as a dielectric, metal, or semiconductor layer. The etch step follows lithography and precedes resist stripping and subsequent deposition or cleaning steps. The Ulvac NE 5500, as an etch system, would occupy this position in the wafer fabrication flow.
