    摘要: In a method of reworking a substrate, an organic anti-reflection coating (ARC) layer is formed on the substrate having an amorphous carbon pattern. A photoresist pattern is formed on the organic ARC layer. The photoresist pattern is entirely exposed when the photoresist pattern has a selected level of defects, and then the photoresist pattern is removed by a developing process. The substrate may be reworked without damaging the organic ARC layer, and the amorphous carbon pattern may include an alignment key and/or an overlay key.

    摘要: In a method of removing a photoresist pattern from a substrate without deteriorating a lower electrode or increasing processing time, ozone gas may be provided onto a substrate on which a photoresist pattern may be formed. An oxidation-decomposition process may be carried out using the ozone gas, to thereby decompose the photoresist pattern on the substrate. The decomposed photoresist pattern may be dissolved into water and removed from the substrate in a rinsing process. Accordingly, a photoresist pattern in an opening having a relatively high aspect ratio may be sufficiently removed from a substrate without deteriorating the lower electrode or increasing processing time.
