WebThe photoresist film was thicker than a multi-spin coating method and the photoresist step coverage over the topology surface was better than the other methods. Moreover, the developed photoresist pattern has a final photoresist film thickness around 4.0 μm on the topology surface, which is suitable for a dry etching process. WebMar 1, 2024 · This ability of dry resist thickness to be co-optimized with photon absorption, transfer etch, and underlayer adhesion allows us to break tradeoffs in line edge roughness, sensitivity, and defectivity/device yield. The dry resist framework has other benefits besides breaking the RLS trade-off. chinese buddhist monks
