  • Patent number: 11702537
    Abstract: A tablet form of an epoxy resin composition for encapsulation of semiconductor elements, where the tablet form of the epoxy resin composition: (i) includes 97 wt % or more of tablets having a diameter of 0.1 mm to less than 2.8 mm and a height of 0.1 mm to less than 2.8 mm, as measured using an ASTM standard sieve; (ii) satisfies the following Equation 1, ? ? ? D × ? ? ? H ? ? ? D + ? ? ? H ? 1.0 , where ?D is a standard deviation of tablet diameters and ?H is a standard deviation of tablet heights, as measured with respect to 50 tablets arbitrarily selected from the tablets; and (iii) the tablets have a compression density of 1.2 g/mL to 1.7 g/mL.

  • Patent number: 11655363
    Abstract: A tableted epoxy resin composition for encapsulation of semiconductor devices and a semiconductor device encapsulated using the tableted epoxy resin composition, the tableted epoxy resin composition satisfying the following conditions (i) a proportion of tablets of the tableted epoxy resin composition having a diameter of greater than or equal to 0.1 mm and less than 2.8 mm and a height of greater than or equal to 0.1 mm and less than 2.8 mm is about 97 wt % or more, as measured by sieve analysis using ASTM standard sieves; (ii) the tablets have a packed density of greater than about 1.7 g/mL; and (iii) a ratio of packed density to cured density of the tablets is about 0.6 to about 0.87.
