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. Webdeveloper solution. The resist pattern depends on the photomask pattern and the polarity of resist. Positive photoresist responds to the light in such a way as to make the exposed regions dissolve more quickly during the development process. In other words, the unexposed regions of the resist will remain unchanged. Negative photoresist responds to
