Water-Debondable Epoxy facilitates solar silicon wafer slicing.
August 19, 2011 -
Providing optimal bond strength to both silicon and glass and metal mounting substrates used during ingot sawing process, LoctiteŽ 3382(TM) protects against wafer breakage. Two-part epoxy adhesive breaks down on exposure to hot water, eliminating corrosive debonding solutions and minimizing silicon waste that occurs during wafer cleaning process. Homogenous and stable, LoctiteŽ 3382(TM) sets up in 5-7 hours, emits no caustic odor, and will not corrode equipment.

New Hot Water Debondable Epoxy Simplifies Solar Silicon Wafer Slicing
SIMPLIFIES SOLAR SILICON WAFER SLICING
LoctiteŽ Adhesive Eliminates Acids and Minimizes Wafer Damage
Rocky Hill, Conn. -- To simplify silicone ingot bonding and protect against wafer breakage, Henkel Corporation has introduced LoctiteŽ 3382(TM), a water-debondable epoxy adhesive that provides excellent bond strength to both silicon and the glass and metal mounting substrates used during the ingot sawing process.
LoctiteŽ 3382(TM) replaces traditional epoxies that require caustic acids for debonding. This adhesive breaks down easily on exposure to hot water, eliminating corrosive debonding solutions and minimizing silicon waste that occurs during the wafer cleaning process.
As this two-part epoxy is pink when cured, it is easy to distinguish from the silicon ingot and the metal and glass mounting substrates during visual inspections. Easy to dispense using meter-mix equipment, LoctiteŽ 3382(TM) is packaged in cartridges, pails and drums. This adhesive emits no caustic odor, will not corrode equipment, and is fully-compatible with current wafer cleaning solutions and processes.
Homogenous and stable, LoctiteŽ 3382(TM) sets up in just 5 to 7 hours and provides a consistent cutting layer that reduces edge damage and wafer breakage. This epoxy's excellent bond strength means the adhesive will not prematurely debond during the sawing process, protecting the ingot and the wafers from damage.
