Semiconductor device having an interposer

摘要

A semiconductor device and a method of fabricating the same. An interposer used for the semiconductor device includes integrated circuits therein to realize the functions of a decoupling capacitor, an ESD preventing circuit, an impedance matching circuit, and termination. The semiconductor device may include a semiconductor die with a through silicon via (TSV) structure having two or more through electrodes that pass through the semiconductor die, in which each of the through electrodes are connected to a respective bond pad of the semiconductor die.
