Title: Developing device and developing method
Inventor: YAMAMOTO TARO
IPC: H01L21/027
Filed: 2004-12-24
Abstract: Temperature of a developing liquid is regulated according to the types of a resist or a resist pattern. A developing liquid is scan-sprayed by a developing liquid nozzle having a slit-form ejection outlet with a length corresponding to the width of an effective area of a substrate. After a developing liquid piled up on the substrate and kept held for a specified time, diluent is scan-sprayed by a diluent nozzle. This substantially stops a developing reaction and diffuses a resist solution component. Thus, a desired amount of resist is quickly dissolved by the temperature regulation of a developing liquid, while developing is stopped by supplying a diluent at a specified timing before an adverse effect is caused by a resist solution component, whereby a pattern with a uniform line width can be obtained and throughput is improved. ® KIPO & WIPO 2007

Title: Multi-step pad conditioning system and method for chemical planarization
Inventor: BENNER STEPHEN J
IPC: B24B1/00
Filed: 2005-01-25
Abstract: An arrangement for performing a multi- step polishing process on a single stage chemical mechanical planarization (CMP) apparatus utilizes an in-situ conditioning operation to continuously clean and evacuate debris and spent polishing slurry from the surface of the polishing pad. By presenting a clean, virtually " new" polishing pad surface at the beginning of each planarization cycle, polishing agents of different chemistries, morphologies, temperatures, etc. may be used without the need to remove the wafer to change the polishing source or transfer the wafer to another CMP polishing station. A multi-positional valve may be used to control the introduction of various process fluids, including a variety of different polishing slurries and conditioning/flushing agents. The use of different conditioning materials allows for the surface of the polishing pad to be altered for different process conditions (e.g., neutralizing prior polishing chemicals, modifying the surface temperature of the pad to control polishing rate, use of surfactants to dislodge particles that become attracted to the pad surface, etc.). ® KIPO & WIPO 2007
