- Encapsulation Of And Coatings For Semiconductor Or Solid State Devices (AREA)
Description
本発明は、半導体装置を構成するパッケージの信頼性を向上させるため、以下のように構成することに特徴がある。すなわち、本発明における半導体装置は、(a)第1表面と前記第1表面とは反対側の第1裏面とを有するヒートシンクと、(b)複数のリードと、第2表面と前記第2表面とは反対側の第2裏面とを有するチップ搭載部と、を有するリード部と、(c)前記チップ搭載部の前記第2表面上に搭載された半導体チップと、(d)前記ヒートシンクの一部、前記リード部の一部、および、前記半導体チップを封止する封止体と、を備える。そして、前記半導体チップと、前記リード部を構成する前記複数のリードとは電気的に接続されており、前記封止体内において、前記ヒートシンクの前記第1表面と前記チップ搭載部の前記第2裏面とが対向するように配置されていることを特徴とするものである。このような特徴的構成を取ることにより、様々な形態のパッケージ製品において、パッケージの信頼性を向上させることができる。つまり、本発明の上述した特徴的構成は、様々なパッケージ製品に適用することができ、それぞれのパッケージ製品が抱える問題点を個別に解決できる利点を有している。以下では、本発明の基本的な技術的思想を具体的な個々のパッケージ製品に適用する例について説明し、本発明によれば、個々のパッケージ製品が抱える問題点を解決できる点について個別具体的に説明する。
本発明の技術的思想を第1パッケージ製品に適用する例について説明する。まず、第1パッケージ製品が抱える問題点について図面を参照しながら説明する。図1は、第1パッケージ製品の構造から本発明の構造に至る流れを模式的に示す図である。図1に示すように、レジンバリ対策前のパッケージ構造としてパッケージPK1という形態が存在している。このパッケージPK1は、矩形形状をした封止体MRの上部から放熱機能を有するヒートシンクHSが突出している。このとき、個々のパッケージPK1はリードフレームで繋がれた状態で製造され、最終的に個々のパッケージPK1に個片化する際、ヒートシンクHSを切断部CT1で切断することにより個片化される。ここで、パッケージPK1では、ヒートシンクHSの上部に切断部CT1が存在する構造をしている。このような構造をしているパッケージPK1では、封止体MRを形成する際、樹脂が漏れ出しレジンバリRBが形成されてしまう事態が発生してしまうことが判明した。レジンバリRBが形成された状態でパッケージPK1が製品として出荷されると、出荷先において、パッケージPK1からレジンバリRBが脱落し、脱落したレジンバリRBが実装基板上の端子上に付着する場合がある。この場合、例えば、実装基板の端子とパッケージ(半導体装置)のリードとを電気的に接続する際、実装基板の端子上に付着した樹脂絶縁物であるレジンバリRBが実装基板上の端子とパッケージのリードとの間の電気的な接続を阻害することになる問題点が発生する。このため、レジンバリRBが形成されてしまうパッケージPK1の構造を改良する必要があることがわかった。
上述したように、互いに隣接するヒートシンクHSを連結部CONで接続することにより、この連結部CONが樹脂封止の際のストッパとして機能するため、レジンバリRBの発生を抑制することができる。したがって、本発明の適用構造でも、互いに隣接するヒートシンクHSを連結部CONで接続する構成を採用している。ところが、互いに隣接するヒートシンクHSを連結部CONで接続すると、リードフレームの成形時に生じるヒートシンクHSのうねり(キャンバー)が原因となって、封止体MRにクラックが発生する。そこで、本発明の技術的思想では、リードフレームを成形する際に生じるヒートシンクHSのうねり(キャンバー)を抑制できる工夫を施している。すなわち、この工夫は、図13に示すように、複数のヒートシンクHSが連結部CONで接続されたヒートシンク部HSUと、アウターリードが形成されているアウターリード部OLUとを分離するものである。これにより、ヒートシンクHSをプレスすることで、アウターリードに対してヒートシンクHSが下方に位置するように成形加工する必要が無くなる。つまり、ヒートシンク部HSUとアウターリード部OLUとを分離することにより、成形加工しなくても、ヒートシンク部HSUをアウターリード部OLUの下方に配置することが可能となるのである。この結果、ヒートシンクHSをプレスしないことから、ヒートシンク部HSUには、キャンバーが発生しなくなり、うねり(キャンバー)に起因した封止体MRへのクラック発生を抑制できるのである。
次に、本発明の技術的思想を第2パッケージ製品に適用する例について説明する。まず、第2パッケージ製品が抱える問題点について図面を参照しながら説明する。
本発明の技術的思想を適用して製造されたパッケージPK6の構成について説明する。図45はパッケージPK6の構造を示す図である。図45(a)は、パッケージPK6を表面側から見た表面図であり、図45(b)は、パッケージPK6を側面側から見た側面図である。また、図45(c)は、パッケージPK6を裏面側から見た裏面図である。
次に、本発明の技術的思想を第3パッケージ製品に適用する例について説明する。まず、第3パッケージ製品が抱える問題点について図面を参照しながら説明する。
図63は、本発明の技術的思想を実現するためのフレーム構造を示す図である。図63に示すように、本発明の技術的思想において、フレームは、ヒートシンク部HSUと、アウターリード部OLUを有し、このヒートシンク部HSUとアウターリード部OLUが分離されている。つまり、本発明の技術的思想の特徴は、複数のヒートシンクHSを連結させたヒートシンク部HSUと、ソースリードポストSPT、ゲートリードポストGPTおよびチップ搭載部TABが形成されたアウターリード部OLUが分離されており、かつ、ヒートシンク部HSUにだけ粗面化処理が実施されている点にある。このような本発明の技術的思想のポイントは、ヒートシンク部HSUとアウターリード部OLUとを分離することにより、ヒートシンク部HSUにだけ粗面化処理を実施することが可能となることである。すなわち、ヒートシンク部HSUとアウターリード部OLUとを一体的に形成すると、ヒートシンク部HSUだけに粗面化処理を実施することが困難になることから、ヒートシンク部HSUとアウターリード部OLUとを分離したものである。
続いて、例えば、第2パッケージ製品に本発明の技術的思想を適用したパッケージPK6の変形例1について説明する。図71は、本変形例1におけるパッケージPK9の構造を示す図である。特に、図71(a)は、本変形例1におけるパッケージPK9の内部構造を示す平面図であり、図71(b)は、本変形例1におけるパッケージPK9の内部構造を示す断面図である。
