What it is
The Ulvac SRH 420 MC Backside is a deposition tool in the Ulvac SRH 420 MC family.[2]
How it works
General reference — not yet source-verifiedA sputter deposition tool uses a plasma to dislodge material from a source and deposit that material onto wafer surfaces.
Backside sputter equipment is used to place a deposited film on the rear surface of a wafer or substrate rather than on the front device side.
Where it fits in the process flow
General reference — not yet source-verifiedA deposition tool sits in the thin-film module of semiconductor manufacturing and follows surface preparation steps that make the wafer ready for film growth.
Backside deposition is used when a rear-surface film is needed for electrical, mechanical, or handling-related purposes before later process steps continue.
Applications
General reference — not yet source-verifiedBackside sputter deposition is used for thin-film formation on the rear side of wafers in semiconductor processing.
Deposition tools of this class are used for film-forming applications where controlled material transfer and coverage on a wafer surface are required.
