What it is
How it works
General reference — not yet source-verifiedStepper systems project a reticle image through reduction optics onto a resist-coated substrate. The stage moves between exposures so the same pattern can be placed at successive locations. Alignment functions register each exposure layer to patterns that are already present on the substrate. Focus and leveling functions keep the image plane matched to the substrate surface during exposure.
Where it fits in the process flow
General reference — not yet source-verifiedLithography sits after substrate preparation and photoresist coating, and before resist development and pattern transfer. A stepper is used after the substrate has been prepared with the film stack to be patterned and before downstream operations such as etching, implantation, plating, or lift-off that use the resist image as a mask.
Applications
General reference — not yet source-verifiedStepper lithography is used wherever repeated patterned features must be placed accurately across a substrate. Tools in this class are applied to semiconductor and related microfabrication patterning steps that use photoresist to define device, interconnect, contact, passivation, or packaging features.
