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. WebIn the experiment, closed to 80 %, 4.3 um of photo resist was eroded during etching, leaving behind appromximately 1.6 um photo resist. The results of this work PR can be useful for multilayer dielectric exceeding 8.5 um for PR further development in TSV integrations.
