What it is
How it works
General reference — not yet source-verifiedPlasma etch equipment operates by admitting process gases into a low-pressure chamber. An electric field energizes the gases into a plasma, creating reactive species that etch exposed film material. The reaction by-products are volatile and leave the chamber through the vacuum exhaust. The AutoEtch 494 functions as this type of plasma etch system.
Where it fits in the process flow
General reference — not yet source-verifiedEtching follows photolithography in the patterning sequence of integrated-circuit manufacturing. A patterned mask protects certain areas of the wafer while the etch tool removes material from exposed areas. The AutoEtch 494 occupies this point in the process flow whenever a dry-etch step is required.
Applications
General reference — not yet source-verifiedThe AutoEtch 494 is used in semiconductor manufacturing for patterning thin films. Etch systems of this type shape films such as conductors, insulators, and semiconductor material to form device structures.
