図6は、バーイン制御回路BTCNTの構成を示すブロック図である。この実施の形態において、バーイン制御回路BTCNTは、図1および図4に示したように、半導体チップCHP2に設けられている。すなわち、ロジック回路およびスタティック型メモリSRAMとともに、1つの半導体チップCHP2に形成されている。バーイン制御回路BTCNTは、特に制限されないが、Bn1~Bn8の入力ノードとBn9~Bn12の出力ノードを備えている。また、同図において、SBTCTは、スタティック型メモリSRAM用のバーイン時間カウンタ回路(第2指定回路)、SCACTは、ロジック回路用のバーイン時間カウンタ回路(指定回路)、DBTCTは、ダイナミック型メモリDRAM用のバーイン時間カウンタ回路(第1指定回路)、BTSQNは、バーイン試験シーケンス回路(シーケンス回路)である。バーイン制御回路BTCNTが、これらのバーイン時間カウンタ回路およびバーイン試験シーケンス回路を備えている。
次に、図7を用いて、バーイン制御回路BTCNTのモード選択を説明する。図7には、バーインイネーブル信号BTEN、リセット信号RSTNおよびバーインモード制御信号MODE0、MODE1の組み合わせと、バーイン制御回路BTCNTの動作モードとの対応が表として示されている。図7に示した表において、モードの列には、バーイン制御回路BTCNTの動作モードが示されている。また、この表において、BTENの列、RSTNの列、MODE0の列およびMODE1の列には、バーインイネーブル信号BTEN、リセット信号RSTN、バーインモード制御信号MODE0およびバーインモード制御信号MODE1の論理値が示されている。なお、ここでも、論理値“1”が有効を示している。
バーン試験シーケンス回路BTSQNは、図7に示した表に従って動作モードを定めると、定めた動作モードに従って、バーイン制御回路BTCNTが動作を行う。図8から図10を用いて、それぞれの動作モードでのバーイン制御回路BTCNTの動作を説明する。図8(A)は、上記した動作モード“(1)DBT動作”において実行されるシーケンスを示しており、図8(B)は、動作モード“(2)SCA動作”において実行されるシーケンスを示しており、図8(C)は、動作モード“(3)SBT動作”において実行されるシーケンスを示している。
次に、滞在時間の設定について、主に図6、図9および図10を用いて説明する。図6において説明したように、バーイン制御回路BTCNTは、スタティック型メモリSRAM用のバーイン時間カウンタ回路SBTCT、ロジック回路用のバーイン時間カウンタ回路SCACT、ダイナミック型メモリDRAM用のバーイン時間カウンタ回路DBTCTを備えている。バーイン時間カウンタSBTCTは、スタティック型メモリSRAMに対応した時間カウント用クロック信号BTCKSのクロック数をカウントし、所定のカウント値に到達する度に、時間到達信号を形成する。同様に、バーイン時間カウンタSCACTは、ロジック回路に対応した時間カウント用クロック信号BTCKLのクロック数をカウントし、所定のカウント値に到達する度に、時間到達信号を形成する。また、バーイン時間カウンタDBTCTは、ダイナミック型メモリDRAMに対応した時間カウント用クロック信号BTCKDのクロック数をカウントし、所定のカウント値に到達する度に、時間到達信号を形成する。
図11は、バーイン試験装置1100の構成を模式的に示した模式図である。同図において、BBD1~BBDnのそれぞれは、バーインボードを示しており、BBDCNTは、バーイン試験において、バーインボードBBD1~BBDnのそれぞれを制御する制御装置を示している。バーイン試験装置1100は、バーイン試験の際には、図示されていないが温度調整機構によって、バーインボードBBD1~BBDnを高温状態にする。また、制御装置BBDCNTは、それぞれのバーインボードBBD1~BBDnに対して、リセット信号RSTN、バーインイネーブル信号BTEN、バーイン用クロック信号TCK、バーインモード制御信号MODE0、MODE1、および時間カウント用クロック信号BTCKS、BTCKL、BTCKDを供給する。また、制御装置BBDCNTは、バーインボードBBD1~BBDnのそれぞれに電源電圧Vdを供給し、バーイン試験のときには、電源電圧Vdを高電圧にする。
図12は、半導体集積回路装置1000の製造方法を示すフロー図である。半導体チップCHP1は、工程S1200~S1202によって製造され、半導体チップCHP2は、工程S1210~S1212によって製造される。
図13は、実施の形態2に係わるバーインボードBBD-2の構成を示すブロック図である。図13には、複数の半導体集積回路装置1000-1~1000-6が、バーインボードBBD-2に搭載された状態が示されている。複数の半導体集積回路装置1000-1~1000-6は、バーン制御回路が異なることを除いて、実施の形態1において説明した半導体集積回路装置と同じ構成を有している。
図15は、実施の形態3に係わる半導体集積回路装置1000の構成を示すブロック図である。図15に示す半導体集積回路装置1000は、図4に示した半導体集積回路装置と類似しているので、ここでは、図4に示した半導体集積回路装置との相違点を主に説明する。
