Silicon Wafer Manufacturing

DELO-DUOPOX Key Features

  • Fast curing at room temperature
  • Low-high viscosities and gap-fill versions available
  • Uniform stress distribution with long-term durability
  • Excellent adhesion to similar and dissimilar substrates

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.
