WebNov 3, 2011 · This paper proposes a new SU-8 fabrication process to simultaneously remove edge bead and tiny air bubbles by spraying out edge bead removal (EBR) fluid over the entire surface of photoresist. WebDescription. This strong galvanised steel bead protects plasterboard edges and forms a defined edge. The edge bead gives you quick and easy bedding in jointing material. It's commonly used to provide strong, defined edges around window reveals, and is available in two sizes to accommodate 12.5mm and 15mm lining boards.

WebEdge Bead Especially in the case of coating thick resist films, a so-called edge bead forms which may cause sticking to the mask as well as an undesired proximity-gap during … WebEdge Bead Removal (EBR) is an equipment-dependent process. Exact application programs (spin speeds and times) depend on wafer size, nozzle placement, spray pressure, amount of edge bead, exhaust flow, wafer bevel and resist solubility. Uniform and repeatable EBR using a TEL™ MARK 8 has been attained with the process steps shown.
