Wafer Backgrinding | Silicon Wafer Thinning | Wafer …

The backgrinding process involves using a diamond-resin bonded grinding wheel to remove the silicon material from the back of a silicon wafer. Using a grinding wheel is highly effective, and faster and less expensive than chemical-mechanical processes and is used to remove the bulk of substrate material prior to final finish grind, polish or chemical etch.

Wafer Backgrinding | Silicon Wafer Thinning | Wafer Backgrind

Back grinding is a step of grinding the back of a wafer thinly. This isn’t just simply about reducing the thickness of a wafer; this connects the front-end process and the back-end process to solve problems that occur between the two processes.

Warping of silicon wafers subjected to back-grinding …

 · This study investigates warping of silicon wafers in ultra-precision grinding-based back-thinning process. By analyzing the interactions between the wafer and the vacuum chuck, together with the machining stress distributions in damage layer of ground wafer, the study establishes a mathematical model to describe wafer warping during the thinning process using the elasticity theory.

The back-end process: Step 3 – Wafer backgrinding | …

With a 2000 grit grinding process, the stress required to break the die was 50 percent higher than the stress needed to break a die with a (larger) 1200 grit grinding process. Figure 2 shows the method of applying the test force to the die, and Figure 3 shows the difference in the scratches on the wafers using different grits to grind the silicon.
