The edge shape and the neck-in value are almost the same between both die widths, which shows that the die width does not affect the neck-in and edge bead
phenomena in these cases.
Epoch die for extrusion coating, meanwhile, will feature the new Edge Bead
Reduction (EBR) internal deckle mechanism that reportedly eliminates edge-trim scrap.
This will maximize the user's ability to detect particles, pits and residues that lead to hot spots on the front side, chips, cracks, and scratches that cause wafer breakage, and edge bead
removal issues that not only harm the individual wafer, but can result in equipment and wafer cross contamination.
Inaccurate wafer centering during the edge bead
removal (EBR) process leads to mis-alignment of the edge exclusion region, the distance from the edge of the wafer to the edge of the active die area.
The EXi Series also automatically performs Edge Bead
Removal (EBR) and Wafer Edge Exclusion (WEE) metrology.
The rising demand for high-performance devices with improved speed and capacity has positively impacted the demand for silicon, reflective coating, contrast enhancers, edge bead
removers, primers or adhesion promoters, specialty solvents, and etchants.

has developed enhancements to extrusion coating dies and internal deckles that make it possible for converters to reduce edge bead
with low-melt-strength polymers while maintaining coat-weight uniformity--two goals that reportedly have often been mutually exclusive with such resins.
Remove the skirtings if you want these to cover the edge gap, a plastic edge bead
is availablefor this if you wish to leave the skirting.
The Flex-Master's 65 mm and 75 mm coextrusion station utilizes a feedblock and 1,500 mm die with internal deckles for edge bead
A plastic edge bead

The ACS300 module offers closed cover coating technology and best-in-class edge bead
removal precision and therefore enables optimum thick resist processing for 3D integration processes.
