Abstract
【解決手段】 ハイサイドスイッチ用のパワーMOS・FETとローサイドスイッチ用のパワーMOS・FETとが直列に接続された回路を有する非絶縁型DC−DCコンバータにおいて、ローサイドスイッチ用のパワーMOS・FETと、そのローサイドスイッチ用のパワーMOS・FETに並列に接続されるショットキーバリアダイオードD1とを同一の半導体チップ5b内に形成した。ショットキーバリアダイオードD1の形成領域SDRを半導体チップ5bの短方向の中央に配置し、その両側にローサイドのパワーMOS・FETの形成領域を配置した。また、半導体チップ5bの主面の両長辺近傍のゲートフィンガ6aから中央のショットキーバリアダイオードD1の形成領域SDRに向かって、その形成領域SDRを挟み込むように複数本のゲートフィンガ6bを延在配置した。

Description
本実施の形態1の半導体装置は、例えばデスクトップ型のパーソナルコンピュータ、ノート型のパーソナルコンピュータ、サーバまたはゲーム機等のような電子機器の電源回路に用いられる非絶縁型DC−DCコンバータである。図1は、その非絶縁型DC−DCコンバータ1の回路図の一例を示している。非絶縁型DC−DCコンバータ1は、制御回路2、ドライバ回路(第1、第2制御回路)3a,3b、パワーMOS(第1、第2電界効果トランジスタ)Q1,Q2、SBD(Schottky Barrier Diode)D1、コイルL1およびコンデンサC1等のような素子を有している。
本実施の形態2では、半導体チップ内におけるSBDの配置位置の変形例について説明する。図25は半導体チップ5bの全体平面図、図26は図25にワイヤWAおよび外部電極7Eを配置した様子を示す半導体チップ5bの全体平面図を示している。なお、図25および図26は平面図であるが図面を見易くするためにゲートフィンガ6a,6bおよびパッドBP1にハッチングを付す。
本実施の形態3では、半導体チップ内におけるSBDの配置位置の他の変形例について説明する。図27は半導体チップ5bの全体平面図、図28は図27にワイヤWAおよび外部電極7Eを配置した様子を示す半導体チップ5bの全体平面図を示している。なお、図27および図28は平面図であるが図面を見易くするためにゲートフィンガ6a,6bおよびパッドBP1にハッチングを付す。
前記実施の形態1は、ローサイドのパワーMOSとSBDとを同一の半導体チップに形成する構成について説明した。しかし、図4の非絶縁型DC−DCコンバータ50Aにおいて、各半導体チップ5a〜5dを別々のパッケージに収容する構成とすると、以下の課題があり、ローサイドのパワーMOSとSBDとを1チップ化した効果が低減されてしまう。本実施の形態4では、これを解決するための構成例を説明する。
図51は本実施の形態5のパッケージ20Cの構成例の平面図、図52は図51のX6−X6線の断面図、図53は図51のY5−Y5線の断面図を示している。なお、図51でも、図面を見易くするため、樹脂封止部材MBを透かして示すとともに、ダイパッド7a1,7a2、リード7bおよび配線部7cにハッチングを付した。
図54および図55は本実施の形態6のパッケージ20Dの図51のX6−X6線およびY5−Y5線に相当する箇所の断面図を示している。なお、パッケージ20D内の様子は図51で示したのと同じである。また、パッケージ20Dの上面は、パッケージ20Dの搭載面(配線基板と対向する面)とは反対側の面である。
DC−DCコンバータの大電流化および高周波化に起因する他の問題として動作時の熱の問題がある。特に、前記実施の形態1,4〜6での説明では、半導体チップ5a,5bを1つのパッケージに収容する構成なので、高い放熱性が必要となる。本実施の形態7では、その放熱性を考慮した構成について説明する。
前記実施の形態1〜7では、SBDとMOSとを同一半導体チップの別領域に形成しているが、この構造では、SBDの形成領域には、MOSの形成領域を配置できないし、半導体チップのサイズは決まっているので、SBDを内蔵した分だけMOSの面積が小さくなり、MOSの導通損失が増大する問題がある。
