Description
また、電磁気障害物を形成することによって、信号線または接続ポイントに現れる高周波ノイズ要素を防止または除去する方法が考案された。電磁気障害物は、半導体デバイスを含むシステム内にパッケージレベルまたは上位(例えば、ボードレベル)レベルで形成される。例えば、多様なシステム−イン−パッケージ(System-In-Package;SIP)及びマルチスタックパッケージ(Multi-Stack Package;MSP)に電磁気障害物が組み込まれている。一般的に、電磁気障害物としてデカップリングキャパシタが使われるが、このような電磁気障害物は、サイズが大きいため、半導体装置に統合されにくいという問題点がある。
