Silicon Wafer Manufacturing
Silicon wafer manufacturing requires precise handling and processing to ensure high yield and minimal damage.
What do Silicon Wafer Manufacturing Adhesives do?
DELO-DUOPOX two-part epoxy adhesives provide a reliable, removable bonding solution for securing silicon ingots to glass substrates during the wafer slicing process.
Cutting individual wafers from silicon ingots is a delicate operation, as the ingot needs to be held in such a way that the silicon is not damaged. This is achieved by using a removable DELO-DUOPOX two-part epoxy to bond the ingot onto a glass substrate.
After the adhesive is cured, the ingot is cut into the individual wafers by an EDM process. The adhesive is then removed by immersing the assembly into a 15% formic acid solution, at 80C, for three minutes. This ensures optimal yields for the wafers.
DELO-DUOPOX Key Features
- Fast curing at room temperature
- Low-high viscosities and gap-fill versions available
- Uniform stress distribution with long-term durability

Why DELO-DUOPOX?
- Uniform Stress Distribution: Minimises mechanical stress during cutting, reducing breakage and improving yield
- Secure Bonding: Holds the silicon ingot firmly in place during EDM (electrical discharge machining) slicing.
- Fast Curing: Cures quickly at room temperature, streamlining production.
- Removable: Easily dissolved in a 15% formic acid solution at 80°C for three minutes, leaving no residue and preserving wafer integrity.
- Versatile Viscosity Options: Available in low to high viscosities and gap-filling versions to suit different ingot geometries.
