Same size die stacking is different from other die stacking in that the bondline thickness must be a minimum of 60µm – 80µm high to ensure enough wirebond-loop height. In short, there are four proven ways to achieve this: Dummy-Die silicon interposer (a space-consuming, expensive and redundant method not discussed here as it is a [...]

Shin-Etsu KJR silicones are used extensively in the manufacture of ICs, transistors, diodes and other semiconductor devices. KJR-4013E is a flexible, moisture-cure silicone most often used as junction-coating resins in the manufacture of diodes. KJR-651E, KJR-655E and KJR-657E are rigid thermoset polyimide-silicones used as junction coating resins in the manufacture of higher power diodes and [...]

Customers often ask what is the maximum aspect ratio (Pellet Height or Length / Pellet Diameter) of epoxy molding compound (EMC).  While this varies from manufacturer to manufacturer, the reason for the maximum aspect ratio is to prevent pellets from cracking or damaging during transportation. For an 18mm Diameter Pellet the Maximum Aspect Ratio is: [...]
