  • TAIKO Process TAIKO Process Grinding Solutions

    The TAIKO process is the name of a wafer back grinding process. This method is different to conventional back grinding. When grinding the wafer the TAIKO process leaves an edge (approximately 3 mm) on the outer most circumference of the wafer and thin grinds only the inner circumference. By using this method it lowers the risk of thin wafer

     · Stresses applied during encapsulation may crack the die and cause other stress-related failures. Optimised wafer strength is needed to ensure reliability during both fabrication and packaging. However grinding anything inevitably leaves flaws on its surface which can weaken both the wafer and the individual dice sawn from it. Given thermal or mechanical stress these flaws may then spread into active regions and may crack the die. Experiments have shown that there are significant differences in the degree of damage between normal grinding

    In the second stage of polishing the wafer is used to finer grain and to thoroughly grind the wafer to the required thickness. For wafers with a diameter of 200 mm they typically start at a wafer thickness of about 720 µm and grind to a thickness of 150 µm or less. Rough grinding typically removes about 90 percent of the excess material.

  • Back Grinding Determines the Thickness of a Wafer SK

     · When the wafer is thick super fine grinding can be performed but the thinner the wafer is the more necessary the grinding is to be carried out. If a wafer becomes even thinner external defects occur during the sawing process. For this reason if the thickness of a wafer is 50㎛ or less the process order can be changed. In this case a Dicing before Grinding (DBC) method is used where sawing for a wafer is performed to half the level before the first grinding.
