Abstract
【解決手段】半導体装置は、電源プレーン25とGNDプレーン13と絶縁体21を有しており、電源プレーン25の周囲に離間してガードリング23を配置し、このガードリング23を、絶縁層を貫通するビア26を介して他層のGNDプレーン13に接続する。電源プレーン25とガードリング23を隔てる間隔は、電源プレーン25とGNDプレーン13を隔てる絶縁体21の厚みより狭い。その結果、RF放射42は、電源プレーンとガードリングとの間で生じる。
【選択図】図5
Description
本発明によれば、電源プレーンの周囲にガードリングを配置し、このガードリングを、ビアを介して他層のGNDプレーンに接続する。その結果、RF放射は、電源プレーンとガードリングとの間で生じるので、不要なRF放射である不要輻射がパッケージ外に放出されるのを抑制することができる。
図3は、本発明の実施形態の半導体装置の全体的な構成例を概略的に示す断面図である。図3の半導体装置は、BGAのボール16と、多層基板の第1層10、第2層20および第3層30と、半導体チップ38と、ボンディングワイヤー44とを具備している。
電源プレーン25に起因するRFノイズによる電磁波が伝搬する様子を図4に矢印として模式的に示した。この電磁波は、ガードリング23と電源プレーン25との間の電位差によりガードリング23で終端されることになる。電源プレーン25とガードリング23とは接近して配置されているため、電磁波が電源プレーン25とガードリング23以外の他の領域に回り込むのを抑制することができる。
また、図3において、配線32と電源プレーン25との間にGNDプレーンを追加したり、配線12とGNDプレーン13との間にさらにGNDプレーンを追加したりしてもよい。このようにすることで、さらにRF放射42が外部に漏れるのを抑制することができる。
