Antireflective coating for microlithography |
摘要 |
<p>A co-polymer of benzophenone and bisphenol A has been shown to have DUV absorption properties. Therefore, the co-polymer has particular utility as an antireflective coating in microlithography applications. Incorporating anthracene into the co-polymer backbone enhances absorption at 248 nm. The endcapper used for the co-polymer can vary widely depending on the needs of the user and can be selected to promote adhesion, stability, and absorption of different wavelengths.</p> |
