S5. CMP & Cleaning Technology

Thursday, February 6 | 1:00 pm - 6:00 pm

CMP & Surface Cleaning for Emerging Technology

As semiconductor devices are reaching their physical limits, there are still many technical challenges to overcome in the future. Logic device should reduce power even further and increase speed more, DRAM memory still needs to shrink to the extreme limits, and 3D NAND needs to be stacked up higher. To achieve these, CMP process needs to reduce variation more than now, defect size and micro scratch caused by CMP should be further reduced to below 20 nm. Also, CMP must overcome extreme step height to achieve planarity while at the same time productivity should be secured.

Cleaning process has already gone beyond the concept of removing normal defects or by products, and it is challenging the limits against the laws of nature in extreme high aspect ratio. In addition, fume control, damaged layer control, drying, bulk material removal with very high selective chemical and environmental factors should be considered.

To overcome these challenges and discuss the present and future of semiconductor CMP and Cleaning process, to reduce the defects caused by CMP to extremely low levels, to implement ultimate drying technology to overcome surface tension, and to provide insights from Revolution to Evolution, in this session, prominent experts in CMP and Cleaning process have been invited and 11 excellent topics presented by experts in each field will be discussed.
