Thinning wafer
WebJan 26, 1994 · Thinning a wafer past a certain limit can result in wafer breakage. A laminated semiconductor wafer structure (10) is assembled to provide mechanical support for the wafer. A semiconductor wafer (12) is affixed to a UV transparent support substrate (16) with a double-sided adhesive tape (14). The tape has dissimilar adhesives on its two … WebNov 28, 2011 · Absorbing light with the backside of the sensor offers many advantages. But the backside thinning must be extremely uniform to have a uniform spectrum sensitivity over the sensor. At imec’s fab, we’ve been able to thin wafers down to 12µm. The best uniformity that can be reached is <2µm thickness variability on 200mm wafers.

Wafer backgrinding is a semiconductor device fabrication step during which wafer thickness is reduced to allow stacking and high-density packaging of integrated circuits (IC). ICs are produced on semiconductor wafers that undergo a multitude of processing steps. The silicon wafers predominantly used today have diameters of 200 and 300 mm. They are roughly 750 μm thick to ensure a minimum of mechanical stability and to avoid warping during high-tem… WebMay 1, 2006 · In order to handle delicate thin wafers the device wafer is bonded to a rigid carrier substrate prior to the back-thinning process. The originally thick device wafer is bonded with its active surface to a carrier wafer using an adhesive bonding layer. After backside processing, including the thinning process and eventually further process steps ...
