grinding; none of the review papers presented any historical views on grinding in manufacturing of silicon wafers; and there was little discussion in the literature on the interrelationships between grinding and other machining processes for silicon wafers.:International Journal of Machine Tools & Manufacture · 2008:Z J Pei · Graham R Fisher · J H Liu · J H Liu: Kansas State University · Sunedison · Huaqiao University:Semiconductor device · Lapping · Sapphire · Polishing · Silicon · Gallium arsenide
Jan 28, 2014· Subsequent to back-grinding, wafer 20 is moved to one or more other machines for polishing, tape removal, and other processing steps related to the prior or subsequent steps. During a multiple-concurrent back-grinding process, two or more wafers 20 are back-ground simultaneously, or at substantially the same time, by a back-grinding apparatus.:Chenfa Lu · Chianghao Lee · Weiyu Chen · Chungshi Liu: Tsmc
The grinding time has been significantly reduced and the lifetime of the grinding stone has been increased thanks to the high stability and lower vibrations. The system is complemented by an optional In-Process Dressing function and a device which automatically measures the thickness of the wafer during the grinding process.
back grinding machines in semiconductor ACCRETECH-TOKYO SEIMITSU is primarily engaged in the sale of: equipment such as wafer slicing machines that cut silicon crystal ingots into silicon substrates called wafers, upon which semiconductor processing is conducted; and, wafer edge grinding machines that
Prior to grinding, wafers are commonly laminated with UV-curable back-grinding tape, which ensures against wafer surface damage during back-grinding and prevents wafer surface contamination caused by infiltration of grinding fluid and/or debris.
