Abstract
An ultra-thin semiconductor chip of an FeRAM, which is miniaturized and highly integrated with characteristic degradation of a ferroelectric capacitor suppressed though a thin package structure is applied to the FeRAM is realized. The semiconductor chip is molded up by using a sealing resin with a filler content set at a value in a range of 90 weight % to 93 weight % to produce a package structure.
