Carrier techniques for thin wafer processing

It should be mentioned that grinding of wafer having solder balls of 140 181;m in diameter on top would definitely result in broken wafer substrate. Therefore bumping of a thin wafer is suggested instead of thinning a bumped wafer [8]. According to this new concept no restriction in wafer thickness and or wafer diameter does appear.
