Characteristics of textured polishing wheels (TPW) for dry fixed abrasive polishing fused silica
Applied Optics, 2023Dry fixed abrasive process integrates chemical reaction and ductile removal into one process and shows advantages against the conventional loose abrasive polishing in efficiency, geometric controllability, and waste disposal. However, it is worth noting that the wear and cutting temperatures encountered during the dry fixed abrasive process are areas ...

Pattern density effects in fixed abrasive polishing
MRS Proceedings, 2002AbstractWe investigated pattern density effects during chemical mechanical planarization (CMP) for shallow trench isolation (STI) applications using fixed abrasive pads to better control the fixed abrasive polishing process. We observed that the polishing characteristics of higher pattern density features are strongly dependent on the presence of lower

Fixed Abrasive Lapping and Polishing of Hard Brittle Materials
Key Engineering Materials, 2010Fixed abrasive lapping and polishing (FALP) is a new machining technology and was adopted to manufacture hard brittle materials and obtain the high productivity because of fixed abrasive. The preparation process of fixed abrasive pad (FAP) was described. FALP of K9 glass, mobile panel glass and Si were investigated with fixed 5-10 µm diamond abrasives.

On the removal of material along a polishing path by fixed abrasives
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2002Material is removed when a surface is polished. This paper presents a model of the removal of material along a polishing path when a surface is polished by fixed abrasives. The proposed model assumes that the pressure distribution is Hertzian at the contact between the tool and the surface and the abrading rate follows the Archard wear law.

Study on the Preparation Technology of Fixed Abrasive Polishing Pad in Chemical Mechanical Polishing
Applied Mechanics and Materials, 2014According to the shortcomings of the traditional free abrasive chemical mechanical polishing (CMP), in recent years, the fixed abrasive chemical mechanical polishing (FA-CMP) technology is proposed. It is a new planarization technology developed on the basis of the traditional CMP. Pad is an important and dispensable part in FA-CMP.
