Description
したがって、本発明によれば、放熱性の高い半導体モジュールを提供することができる。
以下、本発明の第一の実施形態による半導体モジュールについて、図1A、図1Bおよび図2に基づいて説明する。
図1Aおよび図1Bに示すように、第一の実施形態による半導体モジュール1Aは、第一の回路基板2と、第一の回路基板2に対向配置された第二の回路基板3と、第一の回路基板2に接合された第一の半導体素子4と、第二の回路基板3に接合された第二の半導体素子5と、第一の半導体素子4および第二の半導体素子5を相互に電気接続する接続子6と、を備えている。
具体的には、第一の半導体素子4の一方の主面が、はんだ等の導電性接着剤(不図示)によって第一の回路基板2の第一の導電層22Aに接合され、第二の半導体素子5の一方の主面が、はんだ等の導電性接着剤(不図示)によって第二の回路基板3の第一の導電層32Aに接合されている。これにより、第一の半導体素子4が第一の回路基板2の第一の導電層22Aに電気接続され、第二の半導体素子5が第二の回路基板3の第一の導電層32Aに電気接続されている。
上記のように接合された第一の半導体素子4および第二の半導体素子5は、第二の回路基板3と対向する第一の回路基板2の対向面に直交する方向(図1A)において矢印Aの方向、以下、回路基板直交方向Aとする)から見て、互いに重畳しない位置に配置されている。
ここで、回路基板直交方向Aに直交する方向で、第一の半導体素子4および第二の半導体素子5が配列されている方向(図1Aにおいて矢印Bの方向)を第一の回路基板面方向Bとし、回路基板直交方向Aおよび第一の回路基板面方向Bに直交する方向(図1Bにおいて矢印Cの方向)を第二の回路基板面方向Cとして以下説明する。
本実施形態の接続子6は、第一の半導体素子4と接合されている第一の素子接合部61と、第二の半導体素子5と接合されている第二の素子接合部62と、第一の素子接合部61と第二の素子接合部62とを接続する接続部63と、を有している。これらは、第一の素子接合部61、接続部63、第二の素子接合部62の順に第一の回路基板面方向Bの一方側から他方側に配列され、一体に形成されている。
接続子6の第一の素子接合部61および第二の半導体素子5は、ともに第二の回路基板3の第一の導電層32Aに接合されているが、第二の回路基板3の第一の導電層32Aにおいて、接続子6の第一の素子接合部61が接合される領域と、第二の半導体素子5が接合される領域とは、電気的に独立している。
第二の素子接合部62は、第二の半導体素子5とは回路基板直交方向Aに重畳し、第一の半導体素子4とは重畳しないように配置されている。
第二の直方体部62bのうち、第一の回路基板2側の端面は、はんだ等の導電性接着剤(不図示)によって第一の回路基板2の第一の導電層22Aに接合され、第二の回路基板3側の端面は、第二の回路基板3と離間している。
連結部62cは、接合第一の回路基板2、第二の回路基板3、第一の半導体素子4、および第二の半導体素子5に接合されていない。
接続子6の第二の素子接合部62および第一の半導体素子4は、ともに第一の回路基板2の第一の導電層22Aに接合されているが、第一の回路基板2の第一の導電層22Aにおいて、接続子6の第二の素子接合部62が接合される領域と、第一の半導体素子4が接合される領域とは、電気的に独立している。
なお、接続子6は、外部接続リード(不図示)に接合されていてもよい。例えば、図2に示すように、接続子6に外部接続リードと接合される外部接続部64が設けられていてもよい。図2に示す外部接続部64は、第一の素子接合部61から第一の回路基板面方向Bの接続部63と離間する方向に延びる形状に形成されている。
そして、第一の回路基板2および第二の回路基板3に伝わった第一の半導体素子4および第二の半導体素子5の熱は、半導体モジュール1Aの外部に放出することが可能である。例えば、第一の回路基板2や第二の回路基板3において第一の導電層22A,32Aと反対側に位置する他方の導電層22,32にヒートシンクを接触させることで、上記した熱を半導体モジュール1Aの外部に効率よく放出することができる。
第一の実施形態による半導体モジュール1Aでは、第一の半導体素子4と第二の半導体素子5とが回路基板直交方向Aに互いに重畳しない位置に配置されていて、接続子6が第二の半導体素子5を介さずに第一の半導体素子4と第二の回路基板3との間に挟み込まれた第一の素子接合部61を有する。これにより、第一の半導体素子4の熱を第二の半導体素子5を介さずに直接第二の回路基板3に伝えることができる。
また、接続子6が第一の半導体素子4を介さずに第二の半導体素子5と第一の回路基板2との間に挟み込まれた第二の素子接合部62を有することにより、第二の半導体素子5の熱を第一の半導体素子4を介さずに直接第一の回路基板2に伝えることができる。
このため、第一の半導体素子4および第二の半導体素子5の熱を、第一の回路基板2と第二の回路基板3との双方から効率よく放熱させることができる。
以上のことから、放熱性の高い半導体モジュール1Aを提供することができる。
次に、第二の実施形態について、添付図面に基づいて説明するが、上述の第一の実施形態と同一又は同様な部材、部分には同一の符号を用いて説明を省略し、第一の実施形態と異なる構成について説明する。
第二の直方体部71bのうち、第二の回路基板3側の端面は、はんだ等の導電性接着剤(不図示)によって第二の回路基板3の第一の導電層32Aに接合され、第一の回路基板2側の端面は、第一の直方体部71aに接合されている。
接続子7の第一の素子接合部71および第二の半導体素子5は、ともに第二の回路基板3の第一の導電層32Aに接合されているが、第二の回路基板3の第一の導電層32Aにおいて、接続子7の第一の素子接合部71が接合される領域と、第二の半導体素子5が接合される領域とは、電気的に独立している。
第二の直方体部72bのうち、第一の回路基板2側の端面は、はんだ等の導電性接着剤(不図示)によって第一の回路基板2の第一の導電層22Aに接合され、第二の回路基板3側の端面は、第二の回路基板3と離間している。
連結部72cは、第一の回路基板2、第二の回路基板3、第一の半導体素子4、および第二の半導体素子5に接合されていない。
接続子7の第二の素子接合部72および第一の半導体素子4は、ともに第一の回路基板2の第一の導電層22Aに接合されているが、第一の回路基板2の第一の導電層22Aにおいて、接続子7の第二の素子接合部72が接合される領域と、第一の半導体素子4が接合される領域とは、電気的に独立している。
そして、第一の回路基板2および第二の回路基板3に伝わった第一の半導体素子4および第二の半導体素子5の熱は、半導体モジュール1Bの外部に放出することが可能である。
また、本実施形態の半導体モジュール1Bによれば、第一の半導体素子4の一部と第二の半導体素子5の一部とが、回路基板直交方向Aに重畳するように配置されていることにより、第一の実施形態の半導体モジュール1Aと比較して、回路基板直交方向Aから見た大きさを小さくすることができる。すなわち、半導体モジュール1Bの小型化を図ることができる。
例えば、上記の実施形態では、第一の回路基板2および第二の回路基板3の導電層は、セラミック板21,31の両主面に設けられているが、セラミック板21,31の一方の主面のみに設けられてもよい。
また、第一の回路基板2と第二の回路基板3との間には、例えば第一の半導体素子4、第二の半導体素子5および接続子6,7を封止する封止樹脂が設けられてもよい。
このような場合にも、第二の半導体素子5において発生した熱を、第二の回路基板3だけではく、接続子6の第二の素子接合部62Dを介して第一の回路基板2にも伝えることができる。
このような場合にも、第二の半導体素子5において発生した熱を、第二の回路基板3だけではく、接続子7の第二の素子接合部72Eを介して第一の回路基板2にも伝えることができる。
