Webthick positive photoresist SPR 220-7 (up to 14 m) which later was used as a mould for the gold electroplating [8,9]. This thickness was achieved with a single layer coating to get good contact between the mask and the wafer we had to remove the photoresist edge bead which was formed dur-ing the low-speed coating. This was achieved by exposing WebTo realize the micro-moulds, we used SPR 220-7 no-valak based positive photoresist, SU8, 100 XP with a 73% solvent content, (GBL, γ-butyrolactate) epoxy based negative …
