What is the Dicing Process?

The dicing process is used to groove or cut, glass crystals, semiconductors, and many other types of materials. Dicing machines cut wafers into semiconductor chips with the help of blades. Dicing equipment is the instrument used during this process. Dicing technologies are constantly evolving due to the growing demand for thinner wafers and more robust dies, which has a significant impact on dicing equipment manufacturers.

Dicing Process

The dicing process is used in the semiconductor packaging industry. It separates silicon wafers into individual chips. During the process, wafers are mounted using either PVC or Mylar tape. As it has a sticky backing, it holds the wafer on a metal frame. The process is done in a clean area where air constantly circulates, to prevent the complicated circuits imprinted on a wafer, as even the smallest dust particles might damage the process. The tape mounted on wafers has different properties depending on its application. UV curable tapes are used for smaller die sizes, whereas non-UV dicing tapes are used for bigger die sizes. While, the process of wafer dicing, the die remains on the mylar tape. It is retrieved by the equipment named die bonder. The dies are rectangular or square in shape. Their shape depends on the dicing method. Thin wafer processing and dicing equipment are used to process thin wafers. 

The dicing process cuts and creates grooves on board-type workpieces approx. 10 mm thick using dicing blades. The equipment used for dicing is known as a dicing saw. These dicing saw blades are abrasive blades that use synthetic diamonds for abrasive grit. For dicing purposes, different types of blades are used having different grit sizes, shapes, and bond materials.

Hard blades or diamond dicing blades feature high precision and long life. These blades are used in the compound and silicon semiconductor wafers for cutting silicon wafers, grooving, glass, semiconductors, and other materials in the electronic information industry.
