Joining Forces in R&D – An Introduction to our Collaboration Efforts to Improve Defectivity in CMP

Catherine Euvrard-Colnat, CMP R&D manager, CEA-Leti
Silvio Del Monaco, senior staff engineer - STMicroelectronics

CEA-Leti exhibits strengths in characterization and processes capability. There is a common interest for CEA-Leti, STMicroelectronics, and Entegris to study slurry behavior, filtration, and to work on defect reduction. This session will describe our joint development plan and the objectives pursued by the different parties.


Slurry Particle Size and Count Analysis from Lab to Line

Mark Bumiller, technology manager - Advanced Materials Handling

The particle size distribution of the abrasive is a critical parameter affecting the CMP process in several ways. The abrasive mean size and distribution width impacts the material removal rate (MRR). The presence of large particle counts (LPCs) can have a deleterious effect on yield by causing scratches and defects. Entegris provides a range of lab and online solutions for determining mean size and zeta potential by using dynamic light scattering (DLS) and single particle optical sizing (SPOS) technology for LPC monitoring.


Optimizing CMP Slurry Filtration for Performance and Cost of Ownership

Dr. Günter Haas, technologist EMEA – Liquid Microcontamination Control

Slurries used in CMP processes need to be filtered to achieve low defectivity. Past focus has been on control of large particles that can generate scratches. Recently the need to reduce small particles from the slurry, that can generate underlayer defects, has gained attention as well. You will see how nanofiber filtration technology and new developments reduce both types of defects and improve cost of ownership over traditional filters.
