Available in PDF, EPUB and Kindle. Book excerpt: Research was performed to study the particle adhesion on the wafer surface after the chemical-mechanical polishing (CMP) process. The embedded particles can be abrasive particles from the slurry, debris from pad material, and particles of film being polished. Different methods of particle removal mechanism were investigated in order to find out the most effective technique. In post-CMP cleaning, surfactant was added in the solution. Results were compared with cleaning without surfactant and showed that cleaning was more effective with the combined interaction of the mechanical effort from the brush sweeping and the chemistry of the surfactant in the solution (i.e., tribochemical interaction). Numerical analysis was also performed to predict the particle removal rate with the addition of surfactants. The van der Waals forces present in the wafer-particle interface were calculated in order to find the energy required to remove the particle. Finally, the adhesion process was studied by modeling the van der Waals force as a function of separation distance between the particle and the surface. The successful adaptation of elasticity theory to nanoparticle-surface interaction brought insight into CMP cleaning mechanisms. The model tells us that it is not always the case that as the separation distance is decreased, the attraction force will be increased. The force value estimated can be used for slurry design and CMP process estimation.

Available in PDF, EPUB and Kindle. Book excerpt: In the development of next-generation nanoscale devices, higher speed and lower power operation is the name of the game. Increasing reliance on mobile computers, mobile phone, and other electronic devices demands a greater degree of speed and power. As chemical mechanical planarization (CMP) progressively becomes perceived less as black art and more as a cutting-edge technology, it is emerging as the technology for achieving higher performance devices. Nanoparticle Engineering for Chemical-Mechanical Planarization explains the physicochemical properties of nanoparticles according to each step in the CMP process, including dielectric CMP, shallow trend isolation CMP, metal CMP, poly isolation CMP, and noble metal CMP. The authors provide a detailed guide to nanoparticle engineering of novel CMP slurry for next-generation nanoscale devices below the 60nm design rule. They present design techniques using polymeric additives to improve CMP performance. The final chapter focuses on novel CMP slurry for the application to memory devices beyond 50nm technology. Most books published on CMP focus on the polishing process, equipment, and cleaning. Even though some of these books may touch on CMP slurries, the methods they cover are confined to conventional slurries and none cover them with the detail required for the development of next-generation devices. With its coverage of fundamental concepts and novel technologies, this book delivers expert insight into CMP for all current and next-generation systems.

Available in PDF, EPUB and Kindle. Book excerpt: Surface contamination is of cardinal importance in a host of technologies and industries, ranging from microelectronics to optics to automotive to biomedical. Thus, the need to understand the causes of surface contamination and their removal is very patent. Generally speaking, there are two broad categories of surface contaminants: film-type and particulates. In the world of shrinking dimensions, such as the ever-decreasing size of microelectronic devices, there is an intensified need to understand the behavior of nanoscale particles and to devise ways to remove them to an acceptable level. Particles which were functionally innocuous a few years ago are ôkiller defectsö today, with serious implications for yield and reliability of the components. This book addresses the sources, detection, characterization and removal of both kinds of contaminants, as well as ways to prevent surfaces from being contaminated. A number of techniques to monitor the level of cleanliness are also discussed. Special emphasis is placed on the behaviour of nanoscale particles. The book is amply referenced and profusely illustrated. • Excellent reference for a host of technologies and industries ranging from microelectronics to optics to automotive to biomedical. • A single source document addressing everything from the sources of contamination to their removal and prevention. • Amply referenced and profusely illustrated.

This book was released on 2017-09-06 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis addresses selected unsolved problems in the chemical mechanical polishing process (CMP) for integrated circuits using ruthenium (Ru) as a novel barrier layer material. Pursuing a systematic approach to resolve the remaining critical issues in the CMP, it first investigates the tribocorrosion properties and the material removal mechanisms of copper (Cu) and Ru in KIO4-based slurry. The thesis subsequently studies Cu/Ru galvanic corrosion from a new micro and in-situ perspective, and on this basis, seeks ways to mitigate corrosion using different slurry additives. The findings presented here constitute a significant advance in fundamental and technical investigations into the CMP, while also laying the groundwork for future research.

Available in PDF, EPUB and Kindle. Book excerpt: Chemical mechanical planarization (CMP) process has been widely used to planarize a variety of materials including dielectrics, metal, and semiconductors in Si-based semiconductor devices. It is one of the most critical steps to achieve the nanolevel wafer and die scale planarity. However, various contaminants are observed on the wafer surfaces after the CMP process, and they become the most critical yield detractor over many generations of rapidly diminishing feature sizes because they have the most direct impacts on device performance and reliability. This book chapter provides (1) CMP consumables-induced contaminants such as residual particles, surface residues, organic residues, pad debris and metallic impurities, pad contamination, watermark, etc., (2) brush-induced cross-contamination during post CMP cleaning, (3) post-CMP cleaning for removing these contaminants. Fundamental understanding of the formation of various types of CMP contaminants and their characteristics will significantly benefit the development of next-generation CMP slurries and post-CMP cleaning solutions.

This book was released on 2014-06-05 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: With copper and barrier-layer integration firmly in place, several other exciting developments are occurring in the practice of chemical-mechanical polishing (CMP), and many advances are described in this book, first published in 2001. Discussions on CMP for shallow-trench isolation, abrasive-free slurries, improvements in pad and tool configurations including fixed abrasive pads, 'engineered' particles, effects of nanotopography, end-point studies, defect characterization and novel post-CMP cleaning methods are highlighted. Considerable progress has also been reported in modeling the complicated interactions that occur between the wafer surface and the pad and the slurry, whether containing abrasives or abrasive-free, and their influence on dishing and erosion and nonuniformity. These studies offer valuable insights for process improvements and yet many challenges remain and will provide a high level of interest for future books. Topics include: recent developments - pads and related issues; CMP abrasives; copper CMP/STI and planarization; STI and planarization - wear-rate models; low-k and integration issues - particle and process effects in CMP and issues in CMP cleaning.
