Abstract :
The smaller dimension devices demand a constant reduction in microscopic and macroscopic defects. To be able to meet the demands of the next-generation integrated circuits (IC´s), we need to develop processing techniques that can increase performance, reliability and yield. Defect reduction forms the first important goal in this direction. We have identified stress as a good indicator of the defects generated during processing. Rapid photothermal processing is demonstrated as a new thermal process that can effectively replace furnace processing and rapid thermal processing. Considering various process constraints, we have presented a model for process optimization. This approach would lead to improvements in performance, reliability and yield, while reducing processing temperature and processing time. Experimental results showing the effectiveness of rapid photothermal processing are also presented
