Description
特許文献1に開示された回路を検討するのに際して、検討のために特許文献1に基づいて回路を作成した。検討のために作成した回路を図11に示す。図11の(A)に示すように、SiCJFET113とSi型MOSFET114をカスケード接続して、スイッチ素子SW1を構成している。スイッチ素子SW1はドレイン端子Dとソース端子Sとゲート端子Gとを有する。SiCJFET113のゲートGjはソース端子Sを介して回路の接地電位点に接続される。Si型MOSFET114のゲートGmには、入力信号IN0が駆動回路112及びゲート端子Gを介して供給される。すなわち、入力信号IN0に従ってゲート駆動回路(以下ドライバ回路と称することもある)112から、Si型MOSFET114のゲートGmにハイレベル(正電位VDD)又はロウレベル(接地電位VSSM)が供給される。同図において、破線で示されたコイルは寄生インダクタンスL1を示しており、SiCJFET113のドレインからソースに向かう矢印はリーク電流IDSjをSi型MOSFET114のドレインからソースに向かう矢印はリーク電流IDSmを表している。また、破線で示された符号110及び符号111は、SiCJFET113及びSi型MOSFET114がそれぞれ形成された半導体チップを示している。
特許文献2に開示されたスイッチ素子を、例えば2個用意し、電源間に直列に接続して、接続点から信号を取り出す様な回路、所謂インバータ回路を構成した場合、低電位側に接続されるスイッチ素子におけるJFETが誤動作(誤点孤)して、大きな短絡電流が流れてしまう可能性がある。この現象を、図12を用いて説明する。図12の(A)には、特許文献2に開示された内容を、本発明者が検討するために作成した回路が示されている。また、同図の(B)〜(F)には、図12の(A)に示した回路の動作波形が示されている。
(1)インバータ装置:直流電力から交流電力を電気的に生成する電源回路、またはその回路を持つ電力変換装置
(2)インバータ回路:上記(1)の電源回路の一部を構成する回路であって、2つのスイッチ素子を電源間に直列に接続して、その接続点から信号を取り出す回路
(3)インバータ:論理回路の一種の論理否定(NOT)ゲート
先ず、後で詳細に説明する図1及び図2を用いて、実施形態の概要を説明する。
図1には、半導体装置の回路が示されており、図2には、図1に示された回路の動作波形が示されている。
1.スイッチ回路
図1に示すように、半導体集積回路装置SWは、2つの半導体チップ1、2を含んでいる。半導体チップ1には、ノーマリオン型のSiCJFET3が形成されており、半導体チップ2には、ノーマリオフ型のSi型MOSFET4が形成されている。SiCJFET3とSi型MOSFET4は、半導体装置SWに設けられた端子Dと端子Sとの間でカスケードに接続される。すなわち、SiCJFET3のソース・ドレイン経路と、Si型MOSFET4のソース・ドレイン経路は、端子Sと端子Dとの間で直列に接続されている。この半導体装置SWには、駆動回路GDからの信号が供給される。駆動回路GDでは、入力信号INに従った信号IN1、IN0を、ゲート駆動回路5、6が受け、入力信号INに従った信号を、半導体装置SWの端子G1,G0に供給する。端子G1はゲートGjに接続され、端子G0はゲートGmに接続される。入力信号INの電位に従って、SiCJFET3とSi型MOSFET4は、オン/オフする。すなわち、半導体装置SWは、入力信号INに従って、端子Sと端子Dとの間を導通/非道通にするスイッチ回路として動作する(以下、半導体装置SWはスイッチ回路SWともいう。)。この実施の形態では、端子Sは、スイッチ回路SWのソースであり、端子Dはスイッチ回路SWのドレインである。しかしながら、ソースとドレインの表現は、スイッチ回路SWに供給される電流の向きにより変わることに留意して頂きたい。SiCJFET3のソース電極Sjは、Si型MOSFET4のドレイン電極に接続されるため、Si型MOSFET4のドレイン電極を表す場合もある。
次に、図1を用いて説明した半導体装置SWと駆動回路GDを、システムに適用した例を説明する。ここでは、システムとして三相インバータ回路によって駆動されるモータを例にして、その適用例を説明する。
図7には、図1に示したSi型MOSFET4とSiCJFET3を1つのパッケージに封止した半導体装置が示されている。図7(A)は樹脂で封止された状態の半導体装置の平面図が示され、同図(B)では樹脂を取り除いた半導体装置の平面図が示されている。同図(A)に示すように、半導体装置70は、ゲート端子G0、G1、ドレイン端子D、ソース端子S等のリードとヘッダー71を除いて封止樹脂72で覆われている。図7(B)では、封止樹脂72に封止される2枚の金属板PLATE1、2のうち、右側の金属板PLATE2にSi型MOSFET4が形成された半導体チップ2が配置され、左側の金属板PLATE1にSiCJFET3が形成された半導体チップ1が配置された例が示されている。Si型MOSFET4のゲート電極Gmに接続されているゲートパッドGPmは、封止樹脂72から突出するリード(第1リード)であるゲート端子G0に、ソース電極Smに接続されているソースパッドSPmは封止樹脂72から突出するリード(第2リード)であるソース端子Sにそれぞれボンディングワイヤを用いて接続されている。ソースパッドSPmとソース端子Sとは複数本のボンディングワイヤで接続されている。半導体チップ2の裏面に位置するドレイン電極は金属板PLATE2にダイボンディング材料で接続される。一方、左側のSiCJFET3のゲート電極Gjに接続されているゲートパッドGPjは封止樹脂72から突出するリード(第3リード)であるゲート端子G1に、ソース電極Sjに接続されているソースパッドSPjは金属板PLATE2、すなわちSi型MOSFET4のドレイン電極に、それぞれボンディングワイヤを用いて接続されている。ソースパッドSPjと金属板PLATE2とは複数本のボンディングワイヤで接続されている。半導体チップ1の裏面に位置するドレイン電極は金属板PLATE1にダイボンディング部材で接続される。金属板PLATE1と封止樹脂72から突出するリード(第4リード)であるドレイン端子Dとは一体に形成されている。なお、図7(B)に示すように半導体チップ2のチップ面積は半導体チップ1のチップ面積よりも小さい。
