Temporary Bonding Materials | WaferBOND® HT-10.10
WaferBOND® HT-10.10 temporary bonding material enables back-end-of-line processing of ultrathin wafers with standard semiconductor equipment
Brewer Science® WaferBOND® HT materials influence the viability of ultrathin wafers by enabling:
- High throughput
- Process capability up to 220°C
- Ultrathin wafer processing
- Excellent uniformity
WaferBOND® HT materials:
- Protect the wafer edge from chipping
- Protect circuitry from harsh chemical etchants
- Provide a void-free interface for a smooth surface on the final thinned wafer
Added benefits include:
- Low defects
- High yield
- Ability to be applied and removed with EVG® bonding and debonding equipment platform specifically designed to work with WaferBOND® HT materials.
Debonding with the WaferBOND® HT System
The WaferBOND® HT coating is mechanically debonded by heating the processed wafer until the carrier can be slid from the ultrathin wafer.
The WaferBOND® HT system supports high-throughput processes by enabling short debonding times. Debonding time is < 5 minutes.
Material design allows for rapid process throughput from the debonding process.
Stripping Process for WaferBOND® HT Materials
- Residue-free vias with Brewer Science® WaferBOND® Remover
- Reduced defects compared to existing technology
Vias: 0.7 µm wide, 0.7 µm deep
Improve throughput of high-temperature ultrathin-wafer processing
Excellent void-free bonding and high-temperature stability delivered by the WaferBOND® HT product series increases yields and provides greater process latitude.
