Grinding is also a procedure in which the wafer thickness are reduced according to the needs of different industries such as electronics, automotive and ...
In addition, stealth dicing hardly generates debris and allows for improved exploitation of the wafer surface due to smaller kerf loss compared to wafer saw. Wafer grinding may be performed after this step, to reduce die thickness. Dice before grind. The DBG or "dice before grind" process is a way to separate dies without dicing.
Dicing Before Grinding (DBG) of silicon wafers is frequently used for the manufacturing of memory devices with stacked thin die used in mobile devices. It is also adopted in the manufacturing of a wide range of semiconductor devices that need thinner die for the purpose of high-profile manufacturing, such as microcontrollers for mobile device and chips for IC cards.

The Step Cut is performed by Disco's dual spindle dicing saws. Each spindle is equipped with a different dicing blade. This process is a solution to many problems currently faced (e.g. backside chipping) and can be integral in achieving an acceptable process for many different applications and wafer singulation.
Dicing Die Bonding Tape for DBG Process. When applying dicing die bonding tape to separated dies in the DBG (Dicing Before Grinding) process, a process to cut the adhesive layer between the dies is required. High quality adhesive layer cutting of LD Tape is achieved by using full cut laser dicing. 1．

The grinding process is to make the wafer thinner. The current process is used In feed grinding process. A blue tape is adhered on the front side of the wafer, then grind the back of the wafer with the diamond discs which is different from CMP process for the front side of wafer.
Optim Wafer Services is able to offer a Taiko grinding service. This technique leaves ring of full thickness silicon around the outer edge of the wafer while the area where the devices are, can be thinned to as low a 100um and still allow backside processing to occur with no major adaptions to process …
Wafer grinding, ultra thin, TAIKO - dicing … Partial Wafer Grinding is an efficient grinding method to process broken or damaged wafers, or wafer sections. This technique can be employed to process wafers that had been damaged, or wafer sections that are still intact, thereby avoiding loss of the entire wafer material. Get Price

Wafer Sawing is the process of singulating the wafer into individual die ready for subsequent assembly. Alter Technology (formerly Optocap) has the capability for Wafer saw of substrates up to 8" diameter. When dicing of substrates of 12" diameter is required then Optocap can process 12" substrates into smaller segments prior to dicing.
Sep 24, 2020· For this reason, if the thickness of a wafer is 50㎛ or less, the process order can be changed. In this case, a Dicing before Grinding (DBC) method is used, where sawing for a wafer is performed to half the level, before the first grinding. In the order of dicing, grinding and dicing, chips are separated safely from wafers.
In the conventional packaging process of semiconductor manufacturing (TGM, Thin Grinding Mounting), the substrate (wafer) is ground to the designated thickness and then die separation (dicing, cutting process) is performed.

Wafer dies can also be separated without full dicing, using a process called "dice before grind." Here, wafers are pre-diced to a depth below the final required thickness. Then, the wafer is background as normal-backgrinding thins the wafer to beyond the pre-diced depth, leaving separate dies on the backgrinding tape.
