Bonding Material for Mechanical and Laser Release

BrewerBOND® 305

​BrewerBOND® 305 temporary wafer bonding material is an organic coating that enables back-end-of-line (BEOL) processing of ultrathin wafers using standard semiconductor equip- ment. This product improves throughput, simplifies cleaning, and shortens processing time.

Data Sheet Request More Information

BrewerBOND® 305 material is an organic temporary bonding material that improves throughput, simplifies cleaning, and shortens processing time. The material is stable in back-end-of-line processing up to 300°C (depending on downstream process specifications). Debonding is efficient and can be done in two ways. The first method is laser debonding with no force. The second method is mechanical debonding at room temperature with low force. This debonding versatility makes BrewerBOND® 305 material a great option for many different wafer-processing needs.
