800TPH wafer back grinding process

Wafer Grinding Once the vacuum chuck has been machined under controlled grinding conditions, the wafer can be mounted and ground. Since the wafer is very thin, its back surface conforms closely to the chuck surface. The front surface is then ground as flat as possible, again using real-time feed-back control and a ref-erence flat. .

    Wafer Backgrind - www.EESemi.com

    Wafer Backgrind Wafer Backgrind is the process of grinding the backside of the wafer to the correct wafer thickness prior to assembly. It is also referred to as wafer thinning. Wafer backgrinding has not always been necessary, but the drive to make packages thinner and thinner has made it indispensable.
