Abstract
【解決手段】半導体素子が、シリコンまたはエポキシ等の樹脂によって樹脂封止されたP側パッケージユニット21およびN側パッケージユニット22を有し、P側パッケージユニット21およびN側パッケージユニット22は、金属の放熱板4の主面上に、放熱板3の主面が垂直となるように配置されている。P側パッケージユニット21およびN側パッケージユニット22は、放熱板4の主面上に配設されたレール状のユニット装着部50に放熱板3の端縁部が挟まれることで固定される構成となっている。
【選択図】図1
Description
<装置構成>
図1〜図16を用いて本発明に係る実施の形態1について説明する。図1は半導体装置モジュール100の構成を示す斜視図である。
175℃以上の耐熱性を有した接合部を形成することができる。
次に、製造工程を順に示す図8〜図16を用いて、半導体装置モジュール100の製造方法について説明する。なお、以下の説明においては図3に示したP側パッケージユニット21の製造方法を例に採って説明する。
以上説明したように半導体装置モジュール100においては、第2の主電極端子6および第1の主電極端子7と接続部材9との接合において、被接合材(主電極端子)と異なる金属で構成される接合材(例えばはんだ材)を使用することなく、母材である第2の主電極端子6、第1の主電極端子7および接続部材9を溶融し、凝固させることで金属原子どうしを結合させ接合するので、母材と接合材との線膨張係数のミスマッチが発生することがない。
次に、図17を用いて本発明に係る実施の形態2の半導体装置モジュール200の構成について説明する。なお、図3および図4に示した半導体装置モジュール100と同一の構成については同一の符号を付し、重複する説明は省略する。
次に、図18および図19を用いて本発明に係る実施の形態3の半導体装置モジュール300の構成について説明する。なお、図3および図4に示した半導体装置モジュール100と同一の構成については同一の符号を付し、重複する説明は省略する。
図20には、図1に示した半導体装置モジュール100の周囲を樹脂ケース30で囲んだ構成を示す。なお、図1に示した半導体装置モジュール100と同一の構成については同一の符号を付し、重複する説明は省略する。
以上説明した半導体装置モジュール100〜300においては、図2に示した3相インバータIVのうち、インバータIV1を構成する2つの回路ユニットを備えるものとして説明した。このように複数の回路ユニットで1つのモジュールを構成することで、組立性が向上する。
