The circuit diagram is scaled down and then mapped onto the wafer.
WebThe edge bead may also cause focus offset problems if exposure is performed via contact lithography (photomask in direct contact with the photoresist film). A solvent blend (i.e. AZ® EBR 70/30) sprayed along the very edge of a slow spinning wafer (~500-800rpm) is a common method for removing this edge bead.
