thin silicon wafers the process of back grinding for

Oct 22, 2019· Backside Thinning (or BackGrinding)Wafer grindingor backgrounding is the most popular method forthinning wafers. The dimension to which awafercan be thinned depends heavily on the machine used, but most thinsilicon wafershave around 50 micrometers thickness. Anything below that measurement put wafers at risk of suffering from reliability issues. De-bonding thinnedwaferfrom handlingwafers…
