TUTORIAL
STK: CHEMICAL MECHANICAL PLANARIZATION
Instructor: Shyam Murarka, Rensselaer Polytechnic Institute
Sunday, April 7, 6:30 - 11:00 P.M.
Golden Gate A1
The CMP process and historical motivations:
*The present status of CMP particularly focusing on the need to establish
advanced metallization schemes and planarization;
*The large number of variables that control the process;
* The science of CMP -- mechanical and chemical concepts important in
understanding the CMP fundamentals;
*The CMP of the SiO2 films, the most commonly used insulator interlayer
dielectric CMP of two most studied metals, W and Cu.
In spite of being a historically ancient technology, Chemical Mechanical
Planarization (CMP) has never attracted so much attention as it has in the last
few years. This is because of its applicability in planarizing the dielectrics
and metal films used in the silicon integrated circuit (SiIC) fabrication.
Continued miniature-ization of the device dimensions and related need to
interconnect all these devices on a chip have led to building multilevel
interconnections on planarized levels. The difference between the historical
uses of CMP and those in the SiIC fabrication lies in the amount of material
that can be removed prior to achieving the desired planarity. Very thin
volumes of materials have to be precisely removed ending up on a different
material and on a sea of embedded metal and dielectric surfaces. Maintaining
the precise control on the remaining thickness, which is also very small, to
within 0.01-0.05 microns while maintaining the integrity of the underlying
structures are added requirements. This severity of qualifiers of CMP has
challenged the scientists and engineers alike. Understanding the CMP process
with a large number of variables and the science of pad, the abrasives, the
chemistry of the slurry, post-CMP cleaning, feature size dependency, etc. have
become essential in developing a reliable high performance and cost effective
CMP process.
This has led to an unprecedented research and development activity both in the
industrial and university sector as well as in tool and consumable
manufacturers. Rarely, there has been seen such a close association between
these different groups and among various branches of science and
engineering.
