Development of epoxy resin polishing pads with the addition of polymer particles

open access: yesNihon Kikai Gakkai ronbunshu, 2018
Polishing processes are critical to high material removal rate and excellent surface roughness. To realize the highly-efficient polishing of glassware, which are used as materials for flat-panel displays, glass lens, substrates of magnetic disks, a new ...

Performance analysis of Pareto optimal bearings subject to surface error variations [PDF]

open access: yes, 2010
A Pareto optimization study was carried out on a flat pad aerostatic bearing design. Some of the Pareto optimal configurations were then subjected to surface profiling errors including tilt, concavity, convexity and waviness and key performance ...

Effect of nanotopogranphy in direct wafer bonding: modeling and measurements [PDF]

open access: yes, 2005
Nanotopography, which refers to surface height variations of tens to hundreds of nanometers that extend across millimeter-scale wavelengths, is a wafer geometry feature that may cause failure in direct wafer bonding processes.

Effect of Conditioner Type and Downforce, and Pad Surface Micro-Texture on SiO2 Chemical Mechanical Planarization Performance

open access: yesMicromachines, 2019
Based on a previous work where we investigated the effect of conditioner type and downforce on the evolution of pad surface micro-texture during break-in, we have chosen certain break-in conditions to carry out subsequent blanket SiO2 wafer polishing ...
