Fep photoresist
Fluorinated ethylene propylene (FEP) is a copolymer of hexafluoropropylene and tetrafluoroethylene. It differs from the polytetrafluoroethylene (PTFE) resins in that it is melt-processable using conventional injection molding and screw extrusion techniques. Fluorinated ethylene propylene was invented by DuPont and is sold under the brandname Teflon FEP. Other brandnames are Neoflon … WebFor FEP photoresist an all-wet process was demonstrated, and for iP and NEB resists, promising results were achieved with less oxidizing dry strip chemistry. Photon induced …

WebFEP is a melt-processible resin capable of continued service at 400F(204 C). PTFE products are used as gasket and packing materials in chemical processing equipment; as electrical insulation for maximum reliability; and in bearings, seals, piston rings, and other mechanical applications, especially those requiring anti-stick characteristics.

WebFEP Although FEP is similar to PTFE, there are a number of important differences. It has a slightly higher coefficient of friction, lower continuous working temperature and is more transparent than PTFE. FEP has a better gas and vapor permeability and outstanding UV transmission values.
WebTF11 allows an FEP-171 resist film down to about 2000 Å thickness with sufficient etch resistance, while the standard resist thickness for NTAR5 is around 3000 Å.
