第3の目的は、本発明に係る半導体装置またはIPMを用いた電力変換装置を得ることである。
本発明に係る半導体装置は、ベース板と、前記ベース板の上に設けられたパワー半導体素子と、前記パワー半導体素子の主電極端子と、前記パワー半導体素子の物理状態に応じた信号を発するセンサ部と、前記センサ部に接続されるセンサ用信号端子と、前記パワー半導体素子を駆動するための電力を供給する駆動用端子と、前記ベース板の上に設けられ、前記パワー半導体素子、前記主電極端子、前記センサ部、前記センサ用信号端子および前記駆動用端子を収めるケースと、を備え、前記ケースは前記パワー半導体素子よりも上に設けられた上面部を有し、前記センサ用信号端子および前記駆動用端子の上端が、前記ケースの前記上面部と同じ高さ、または、前記上面部よりも高い位置にあり、前記パワー半導体素子の駆動の制御または前記センサ用信号端子の出力する信号に応じた前記パワー半導体素子の保護動作の制御を行う制御回路は前記ケースに収められない。
図1は、本発明の実施の形態1に係る半導体装置30および制御基板32の断面図である。半導体装置30ではベース板34の上にケース36が配置される。ケース36の内側において、ベース板34には配線パターン38がはんだ40によって接合されている。配線パターン38の上面には絶縁基板42が配置される。絶縁基板42の上面には配線パターン44が配置される。配線パターン44の上面にはパワー半導体素子46およびセンサ部47がはんだ48によって接合される。センサ部47はパワー半導体素子46の温度に応じた信号およびパワー半導体素子46を流れる電流に応じた信号を発する。
図10は、本実施の形態に係る半導体装置30と制御基板32を接続した状態の断面図である。本実施の形態では、半導体装置30はセンサ用信号端子202および駆動用端子222を備える。矢印114に示すように、センサ用信号端子202および駆動用端子222の上端は、ケース36の上面部104よりも高い位置にある。
図11は、本実施の形態に係る半導体装置30の断面図である。本実施の形態に係る半導体装置30は、実施の形態1の場合と同様にセンサ用信号端子203および駆動用端子223を複数備える。センサ用信号端子203および駆動用端子223のうち、一部は上端がケース36の上面部104より低く、一部は上端がケース36の上面部104より高い。ここで、図11においてセンサ用信号端子203および駆動用端子223は重なっているため、2本のみが描かれている。
図13は本実施の形態に係る半導体装置30の断面図である。本実施の形態では、半導体装置30はセンサ用信号端子204および駆動用端子224を備える。センサ用信号端子204および駆動用端子224の一部または全てはプレスフィット端子123で構成される。
図16は、本実施の形態に係る半導体装置30の断面図である。本実施の形態では、半導体装置30は配線パターン44から取り出される信号を出力するセンサ用信号端子205を備える。センサ用信号端子205は、信号配線用ボンディングワイヤ60によって配線パターン44に接続される。配線パターン44にはパワー半導体素子46が搭載されている。配線パターン44によれば、例えばパワー半導体素子46の裏面から信号を取り出す事ができる。
図17は本実施の形態に係る半導体装置30の断面図である。本実施の形態では、半導体装置30はセンサ用信号端子206および駆動用端子226を備える。センサ用信号端子206および駆動用端子226はメス型端子125で構成される。またメス型端子125の上端はケース36の上面部104と同じ高さである。
図19は、本実施の形態に係る半導体装置30の断面図である。本実施の形態では、センサ用信号端子207および駆動用端子227は配線パターン44の上に配置される。本実施形態の構成によれば、センサ用信号端子207および駆動用端子227を、実施の形態1の場合と比較してパワー半導体素子46に近づけることができる。このため、インピーダンスの低減および高速な応答が可能になる。また、センサ用信号端子207および駆動用端子227を取り出す位置の自由度が向上する。このため、制御基板32のレイアウトの自由度が向上する。また、絶縁基板42の周囲に設けた端子を配置するためのスペースを削減できるため、半導体装置30の小型化が可能になる。
図20は、本実施の形態に係る半導体装置30の断面図である。本実施の形態では、ケース36の内部を封止樹脂126で充填している。充填の方法には、内部配線を硬質樹脂で封止するダイレクトポッティング構造およびトランスファーモールド樹脂による充填がある。また、本実施の形態では、半導体装置30はセンサ用信号端子204および駆動用端子224を備える。センサ用信号端子204および駆動用端子224はプレスフィット端子123で構成される。
図21は、本実施の形態に係る電力変換装置134の平面図である。電力変換装置134は、実施の形態1〜8の半導体装置30、半導体装置30を使用した2つのIPM70および4つの3相インバータ130を備えている。半導体装置30には、ユーザーが準備した制御基板132が接続されている。半導体装置30、IPM70および3相インバータ130は、バスバー136に接続されている。電力変換装置134はインバータ装置を構成している。
本実施の形態では、実施の形態1〜9の半導体装置30、IPM70および電力変換装置134に備えられるパワー半導体素子46はワイドバンドギャップ半導体で形成される。ワイドバンドギャップ半導体は、炭化珪素、窒化ガリウム系材料またはダイヤモンドである。
