Abstract

A stacked bottom lead package for use in semiconductor devices includes leads that are bent along with the circumference of the body which has been premolded, wherein a chip is included inside the premolded body. The package configuration prevents solder fatigue of the lead due to heat carried via the extended lead and emitted out of the chip and decreases the area required for stacking semiconductor packages.
