Paper Abstract
As the semiconductor industry moves into deeper sub-quarter micro regime, minimization of post develop process defects is of paramount significance in manufacturing environments. Reduce defects levels can significantly increase the yield in production, resulting in substantial cost savings and also reduce time to market of new devices. Typical approaches to reduce defect levels include extension of the DI rinse time immediately after completion of photoresists development, use of multiple rinse steps and variable rinse spin speed. However, many of these penalize the process throughput. The uniqueness of this project was the use of enhanced rinse hardware with a mechanistic understanding and characterization of defect generation for an advanced DUV resist.
