Description
本発明の他の目的は、3次元LSIを製造するにあたって、製造コストを低減することのできる半導体装置の製造方法を提供することにある。
本発明に依れば、更に、3次元LSIを製造するにあたって、製造コストを低減することのできる半導体装置の製造方法が提供される。
まず、半導体ウェハ15上に複数のチップ1が形成される。図5は、複数のチップ1が形成された半導体ウェハ15の平面図である。各チップ1には、貫通電極2や接続電極7が形成されている。但し、図5においてこれらの電極は図示されていない。
続いて、半導体ウェハ15がチップグループ6単位でダイシングされる。本実施の形態では、一のチップグループ6は、4枚のチップ1によって構成されている。尚、半導体ウェハ15上に形成された複数のチップ1のうち、端部に位置していてチップグループ6としては切り出せないチップは、チップ1単体でダイシングされる。
続いて、ダイシングされた各チップグループ6のうちで、良品チップのみで構成されるものだけが選別される。良品チップのみのチップグループ6は、次のステップS40の処理が施される。一方、不良チップを含むチップグループ6に対しては、次のステップS60以降の処理が施される。
続いて、選別された良品のみのチップグループ6を積層する。積層にあたっては、まず、チップグループ6を、Sn−Agめっき膜14側の電極が下側になるように、フリップチップボンダーで把持する。続いて、別のチップグループ6の表面側(Au、Niめっき層側)の接続電極7に、Sn−Agめっき膜14を位置決めする。更に、250℃に加熱しながら積層する。これにより、比較的融点の低いSn−Agめっき膜14が溶融し、接続電極7のAu、Niめっき膜(11、12)に接合する。この工程を繰り返して、チップグループ6を8層積層する。更に、最下層のチップグループ6とインターポーザ基板5の基板内配線8とも同様に接合させることで、図1、3に示される半導体装置17が得られる。
ステップS40までの工程で得られた半導体装置17を、モジュール3単位にダイシングする。これにより、図2に示されるような一のチップ1が積層した構造を有する半導体装置を得ることもできる。即ち、図3に示される切断線に沿って、半導体装置17をダイシングることで、4つのモジュール3を得る事ができる。
一方、ステップS30の選別時に、不良チップを含んでいたチップグループ6は、S50の積層を行わずにチップ1単位にダイシングされる。そして、チップ単位で良品チップと不良チップとの選別が行われる。良品チップは、次のステップS70の処理が施される。不良チップは、廃棄される。
S60の処理で良品であったチップは、チップ単位で積層される。この時の積層は、S40の処理と同様に行われる。このステップS60、S70の処理により、不良チップグループ内に含まれる良品チップは無駄とならず、歩留まりを落とすことがない。
2229個のチップが良品モジュールとして製品化され、残りの2995個は廃棄される。本来不良であるチップは、518個のみであるので、2477個のチップは、良品であるにも関わらず廃棄される。従って、上述したBOB(4)と同様に、良品チップの廃棄損失を算出すると、1774(円/モジュール)となる。
