Back Grinding Determines the Thickness of a Wafer
The thinner semiconductor chips are, the higher the integration can be through higher chip stacking. However, that leads to the lower performance of the product at the same time, thus there is a contradiction that the performance should be improved through back grinding. Therefore, the grinding method that determines the thickness …
