Silica Detection in H2SO4 and HCl with Universal Surface-Enhanced Raman Spectroscopy​

Constant developments in the microelectronics industry, with finer line widths and the requirement of essentially particle-free water, also brings with it many challenges involving the conservation and reuse of water, treatment of growing streams of wastewater produced from high-purity water from processes such as CMP, photolithography and etchant rinsing. This article provides an overview of featured keynote speakers, technical presentations on UPW and process water/wastewater as well as Roundtable Networking session at the UPW Micro 2015 conference.

Critical feature sizes of modern semiconductor devices have surpassed the capabilities of traditional optical-based methods to measure particle concentrations in process chemicals and on wafers. Without adequate metrology for quantifying particle and particle precursor concentration in process chemicals, device makers face challenges correlating component failures and fabrication steps. This is especially true for organic material released by Final Polish Ion Exchange resin during a rinse cycle, which is not detected efficiently using optical methods. In this work, we describe two state-of-the-art measurement methods that can detect organic particles and particle precursors to 3 nm using Aerosolization and Threshold Particle Counting (TPC) and defects from UPW deposited on a wafer surface down to 8 nm using Surfaced Enhanced Particle Sizing (SEPS)

This webinar features a presentation from Nabil Mistkawi, Samsung Austin Semiconductor, who identifies key technology requirements for wet chemicals and gases from an end user perspective. This was followed by an engaging discussion between tool OEM companies and end users, as they explored the contamination control needs of individual environments, showing where contamination impacts the process, thereby bringing together the supply chain with the clean room.

This Q&A session took place at the 2020 Ultrapure Micro annual conference. It was a part of the Ultrapure Water Production track, and included speakers from the Wafer Contamination Control - Particles Monitoring session.
