- FIG. It is a figure which shows the structure of the laminated semiconductor chip in a modification. It is a figure which shows the other structure of the laminated semiconductor chip in a modification.
- FIG. 2B shows a waveform when the switching element constituting the upper arm is turned on. Specifically, when the switching element that constitutes the upper arm is turned on, the junction FET Q1a and the MOSFET Q2a that constitute the upper arm are turned on. The return current flows through a path that passes through LL and returns to the power supply VCC. At this time, as shown in FIG. 2B, the voltage Vdsmu changes from a predetermined voltage to about 0 V, while the voltage Vak is about 0 V to a power supply voltage when the upper arm switching element is turned off. To rise.
- the parasitic inductance Lse2 functions to increase the current flowing from the drain Dj2 to the source Sj2 of the junction FET Q1b. For this reason, when the parasitic inductance Lse2 increases, a large current flows transiently from the drain Dj2 of the junction FET Q1b toward the source Sj2. As a result, the charge flowing into the drain Dm2 of the MOSFET Q2b increases rapidly, and as a result, the voltage Vdsmd increases rapidly. This is the first mechanism.
- a parasitic capacitance is formed between the drain Dj2 and the gate electrode Gj2 of the junction FET Q1b.
- the voltage applied to the parasitic capacitance also changes.
- the electrostatic capacitance value of this parasitic capacitance becomes a comparatively large value, the charging / discharging electric current which generate
- This charge / discharge current flows between the gate electrode Gj2 of the junction FET Q1b and the source S2 of the lower arm. At this time, the charge / discharge current is a current that changes over time.
- the charge flowing into the drain Dm2 of the MOSFET Q2b increases rapidly, and as a result, the voltage Vdsmd increases rapidly.
- the second mechanism since a positive voltage is applied to the gate electrode Gj2 of the junction FET Q1b, in order to cut off the junction FET Q1b, it is larger than when 0 V is applied to the gate electrode Gj2. A voltage must be applied to the source Sj2 of the junction FET Q1b. Also from this viewpoint, the voltage Vdsmd that increases until the junction FET Q1b is cut off increases.
- the voltage Vdsmd rapidly increases by the first to third mechanisms related to the parasitic inductance Lse2, the parasitic inductance Lgi2, and the parasitic resistance.
- the voltage Vdsmd which is the drain voltage of the lower arm MOSFET Q2b rises to a voltage equal to or higher than the withstand voltage of the MOSFET Q2b, thereby causing the lower arm MOSFET Q2b to avalanche.
- the lower arm MOSFET Q2b will be destroyed eventually.

- the semiconductor chip CHP2 is biased toward the front side of the chip mounting portion PLT2, in other words, the semiconductor chip CHP2 is mounted on the back side of the chip mounting portion PLT2. It means that there can be a large space that is not.

- the conductor resistance becomes smaller than that of the wire, so that the parasitic inductance can be reduced. That is, by using the clip CLP having a metal plate structure, the parasitic inductance existing between the gate pad GPj and the source lead SL and the parasitic inductance existing between the source pad SPm and the source lead SL are reduced. can do.

Specifically, in the package PKG3 shown in FIG. 5, the gate lead GL is disposed on the leftmost side, the drain lead DL is disposed in the middle, and the source lead SL is disposed on the rightmost side.
- the distance between the gate pad GPj and the source lead SL can be shortened.
- the length of the wire Wgj connecting the gate pad GPj and the source lead SL can be shortened. That is, also in the package PKG6 shown in FIG. 9, the parasitic inductance existing in the wire Wgj can be sufficiently reduced. From this, it is possible to suppress the voltage application to or higher than the withstand voltage to the MOSFET by the second mechanism described above, and thereby it is possible to effectively suppress the avalanche breakdown of the cascode-connected MOSFET. As a result, the reliability of the semiconductor device can be improved also in the package PKG6 shown in FIG.

<本発明者が見出した課題の詳細>
地球環境保全という大きな社会潮流の中で、環境負荷を低減するエレクトロニクス事業の重要性が増している。中でもパワーデバイス(パワー半導体装置)は、鉄道車両、ハイブリッド自動車、電気自動車のインバータやエアコンのインバータ、パソコンなどの民生機器の電源に用いられており、パワーデバイスの性能改善は、インフラシステムや民生機器の電力効率改善に大きく寄与する。電力効率を改善するということは、システムの稼働に必要なエネルギー資源を削減できるということであり、言い換えれば、二酸化炭素の排出量削減、すなわち、環境負荷を低減できる。このため、パワーデバイスの性能改善に向けた研究開発が各社で盛んに行われている。
図2(a)は、カスコード接続した接合FETとMOSFETとをスイッチング素子として利用したインバータを示す回路図である。図2(a)に示すインバータは、電源VCCに直列接続された上アームと下アームとを有している。上アームは、ドレインD1とソースS1との間に接続されたスイッチング素子から構成されている。上アームを構成するスイッチング素子は、カスコード接続された接合FETQ1aとMOSFETQ2aから構成されている。具体的には、接合FETQ1aのドレインDj1がスイッチング素子のドレインD1と接続され、接合FETQ1aのソースSj1がMOSFETQ2aのドレインDm1と接続されている。そして、MOSFETQ2aのソースSm1がスイッチング素子のソースS1と接続されている。また、接合FETQ1aのゲート電極Gj1は、スイッチング素子のソースS1と接続され、MOSFETQ2aのゲート電極Gm1と、スイッチング素子のソースS1との間にはゲート駆動回路(G/D)が接続されている。
図3は、本実施の形態1におけるパッケージ(半導体装置)PKG1の実装構成を示す図である。図3に示すように、本実施の形態1におけるパッケージPKG1は、互いに電気的に絶縁された2つのチップ搭載部PLT1とチップ搭載部PLT2を有している。図3において、右側に配置されている金属プレートがチップ搭載部PLT1を構成し、左側に配置されている金属プレートがチップ搭載部PLT2を構成している。チップ搭載部PLT1は、ドレインリードDLと連結されるように一体的に形成されており、チップ搭載部PLT1とドレインリードDLとは電気的に接続されている。そして、このドレインリードDLを離間して挟むように、ソースリードSLとゲートリードGLが配置されている。具体的には、図3に示すように、ドレインリードDLの右側にソースリードSLが配置され、ドレインリードDLの左側にゲートリードGLが配置されている。これらのドレインリードDL、ソースリードSL、および、ゲートリードGLは、互いに電気的に絶縁されている。そして、ソースリードSLの先端部には、幅広領域からなるソースリードポスト部SPSTが形成され、ゲートリードGLの先端部には、幅広領域からなるゲートリードポスト部GPSTが形成されている。

前記実施の形態1では、パッケージ構造に関する工夫点について説明したが、本実施の形態2では、デバイス構造に関する工夫点について説明する。
図25は、本実施の形態2における半導体チップのレイアウト構成を示す図である。以下に示す半導体チップのレイアウト構成は、例えば、シリコンカーバイド(Si)に代表されるシリコン(Si)よりもバンドギャップの大きな物質を材料とする接合FETを形成した半導体チップCHP1上に、シリコン(Si)を材料とするMOSFETを形成した半導体チップCHP2を積層して搭載する例を示している。図25において、半導体チップCHP1は矩形形状をしており、この矩形形状をした半導体チップCHP1の外周領域にターミネーション領域TMjが形成されている。このターミネーション領域TMjは、耐圧を確保するために設けられている領域である。そして、ターミネーション領域TMjの内側領域がアクティブ領域ACTjとなっている。このアクティブ領域ACTjに複数の接合FETが形成されている。
続いて、本実施の形態2における積層半導体チップの他のレイアウト構成について説明する。図28は、本変形例における積層半導体チップのレイアウト構成を示す図である。図28に示すように、半導体チップCHP1は矩形形状をしており、この矩形形状をした半導体チップCHP1の外周領域にターミネーション領域TMjが形成されている。そして、ターミネーション領域TMjの内側領域に、アクティブ領域ACTj、ゲートパッドGPj、および、ソースパッドSPjが形成されている。ここで、本変形例の特徴は、アクティブ領域ACTj、ゲートパッドGPj、および、ソースパッドSPjが平面的に重ならないように配置されている点である。つまり、図28に示すように、接合FETが形成されるアクティブ領域ACTjは、ゲートパッドGPjやソースパッドSPjを避けるように配置されている。そして、ソースパッドSPj上に半導体チップCHP2が搭載されている。
次に、半導体チップCHP2に形成されているMOSFETのデバイス構造の一例について説明する。図31は、本実施の形態2におけるMOSFETのデバイス構造の一例を示す断面図である。図31に示すように、例えば、n型不純物を導入したシリコンからなる半導体基板SUBmの裏面には、例えば、金膜からなるドレイン電極DEmが形成されている一方、半導体基板SUBmの主面側には、n型半導体領域からなるドリフト層DFTmが形成されている。ドリフト層DFTmには、p型半導体領域からなるボディ領域PRが形成されており、このボディ領域PRに内包されるように、n型半導体領域からなるソース領域SRが形成されている。このソース領域SRとドリフト層DFTmで挟まれた、ボディ領域PRの表面領域がチャネル形成領域として機能する。そして、ソース領域SRとボディ領域PRの両方に電気的に接続するようにソース電極SEが形成されている。さらに、チャネル形成領域上を含むドリフト層DFTmの表面には、例えば、酸化シリコン膜からなるゲート絶縁膜GOXが形成されており、このゲート絶縁膜GOX上にゲート電極Gが形成されている。
次に、本発明者が見出した新たな課題について説明する。図32は、カスコード接続されたスイッチング素子における電流経路を示す図である。図32(a)は、オン時の電流経路を示す図であり、図32(b)は、オフ時に流れるリーク電流の電流経路を示す図である。図32(a)に示すように、オン時においては、定格電流Idが接合FETQ1のドレインからMOSFETQ2のソースへ流れる。すなわち、カスコード接続されたスイッチング素子のドレインDからソースSに向って定格電流Idが流れる。このとき、MOSFETQ2がカットオフされる前のMOSFETQ2のドレイン電圧(中間ノードSeの電圧)は、MOSFETQ2のオン抵抗と定格電流Idの積から求めることができる。例えば、オン抵抗が10mΩで、定格電流Idが40Aであれば、中間ノードSeの電圧は0.4Vである。この中間ノードSeの電圧は、MOSFETQ2のドレイン電圧であるとともに、接合FETQ1のソース電圧でもあるため、接合FETQ1のソース電圧を基準とした接合FETQ1のゲート電圧である電圧Vgsは、-0.4Vである。
図33は、本実施の形態2における接合FETのデバイス構造を示す断面図である。図33に示すように、本実施の形態2における接合FETは、半導体基板SUBjを有し、この半導体基板SUBjの裏面にドレイン電極DEjが形成されている。一方、半導体基板SUBjの裏面とは反対側の主面側には、ドリフト層DFTjが形成されており、このドリフト層DFTjには、複数のトレンチTRが形成されている。そして、複数のトレンチTRのそれぞれの側面および底面には、ゲート電極GE(ゲート領域ともいう)が形成されており、隣り合うトレンチTRの側面および底面に形成されたゲート電極GEに挟まれるようにチャネル形成領域が形成されている。このチャネル形成領域の上部にはソース領域SRが形成されている。このように構成されている接合FETでは、ゲート電極GEに印加する電圧を制御することにより、ゲート電極GEからの空乏層の延びを制御する。これにより、互いに隣り合うゲート電極GEから延びる空乏層が繋がるとチャネル形成領域が消失してオフ状態が実現される一方、互いに隣り合うゲート電極GEから延びる空乏層が繋がらない場合には、チャネル形成領域が形成されてオン状態が実現される。
