Fine grinding of silicon wafers: a mathematical model for grinding
网页Another approach is etched-waferfi ne grinding [14]. Fine grinding is used to partially replace the rough-pol-ishing process, addressing two problems associated with the traditional process fl ow: poor fl atness and high cost. Fine grinding of etched wafers fi rst appeared in public domain through the US patent by Vandamme et al. [14].
