WebThe positive resist Shipley 1827 has been found to create layers up to 6 microns thick, while SU-8 can theoretically produce layers up to hundreds of microns thick [10]. 3 SU-8 Photopolymer... WebIntroduction The S1813 series resist is a standard novolak based positive photoresist that can be used in a wide variety of process flow to perform wet etch, dry etch and even lift-off processes. Its resistance depends on the etch process and can vary a lot. WebWe applied Shipley 1827 photoresist to the nitride surface, and patterned it using a Karl Suss MA6 mask aligner. We then etched the nitride layer using CHF 3 /O 2 plasma in a Plasma-Therm 790 RIE. After etching, the photoresist was stripped in acetone, followed by a brief treatment in an oxygen plasma to remove any remaining resist. new york to cayman island direct flight
