What it is
How it works
General reference — not yet source-verifiedAutomatic dicing saws separate a wafer into individual dice by cutting along predefined streets with a high-speed rotating blade. The wafer is mounted on a dicing tape and held on a vacuum chuck that moves under the blade along a programmed cutting path. A spindle motor rotates the blade at a controlled speed while a coolant stream—typically deionized water—removes cutting debris and dissipates heat. An optical alignment system locates fiducials or pattern features on the wafer to correct for rotation and offset before cutting begins. After each cut, the stage indexes to the next street; multiple blades and cutting passes can be programmed for different material layers.
