silicon wafer backgrinding process Solutions Just Right For You

Wafer dicing is the process by which individual silicon chips (die) are separated from each other on the wafer. The dicing process is accomplished by mechanically sawing the wafer in the extra areas between the die (often referred to as either dicing streets or scribe lines). To facilitate the sawing of the wafer, backside support [] generated during wafer back grinding process affect the microstructure and enhance the mechanical strength of the low-k stack. 1.

Backgrinding Applications Reclaim Wafers. With the ever increasing pressure on costs, many chip manufacturers are moving towards wafer reclaim for monitor wafers. This process reduces the cost of buying fresh wafers for monitoring less critical processes in the fab, and with the development of our new technology grinding wheels, allows the reclaim wafers to have similar surface characteristics

Wafer backgrinding starts with a large grit wheel to remove most of the surface, and wheels with a finer grit are used to finish polishing the silicon wafer to the desired thickness. To prevent contamination, deionized water is used to wash debris from the surface throughout the wafer thinning process. The use of protective tape also helps prevent breakage and damage to the wafer front surface

Engineered Bond System, BXL6550, for Improved Wafer Strength - Especially For Thin Wafer Grinding. In an effort to improve the process of grinding thin wafers, it was essential to develop wheels that impart minimal sub-surface damage and residual stress to the wafers during grinding. Such a wheel could potentially reduce or eliminate the need

Backgrinding: CORWIL uses automated and semi-automated Disco equipment and grind wheels to process wafers. Speeds, grind wheel grits, and selection of appropriate WSS (wafer support system) tapes all play a role in processing exotic materials. Through repeated process verification activities, we select grind wheels and parameters that are suitable for each wafer's specific characteristics

Wafer backgrinding is a semiconductor device fabrication step during which wafer thickness is reduced to allow for 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
