What is the DBG (Dicing Before Grinding) process?
This is a die fabrication process in which, after the circuit surface has been half-cut, the wafer is made ultra-thin through back grinding while the die is diced. With an in-line system comprised of the Lintec's Fully-Automatic Multifunction Wafer Mounter (RAD-2510F/12Sa) and Disco Corporation's grinder, the risk of damage to wafers is reduced and ultra-thin dies (25µm or less) can be produced with stability.
BG Tape for DBG Process
This is a back grinding tape that fully prevents infiltration of grinding fluid during polishing, as well as the generation of dies or cracks. The tape is laminated by the "RAD-3500 series," BG Tape Laminator.

Pick-up Tape for DBG Process
A special-purpose pick-up tape for fully transferring chips, diced after back grinding, from surface protective tape to ring frame. The tape is mounted with the "RAD-2510 F/12Sa," Fully-Automatic Multifunction Wafer Mounter.

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.



At Lintec's Research Laboratory (Saitama Prefecture) and Agatsuma Plant (Gunma Prefecture), where tapes for semiconductor manufacturing are developed and manufactured, and at the Ina Technology Center (Saitama Prefecture) where related equipment are developed and manufactured, certification has been obtained for the ISO 9001 quality management system and the ISO 14001 environment management system.
