Description
図1は、本発明の第一実施形態に係る半導体装置100の構成例を、模式的に示す斜視図である。図2(a)は、半導体装置100を構成する半導体チップ102の平面図である。半導体装置100は、主に、ベース基板101と、ベース基板101上に積層された複数の半導体チップ102と、複数の半導体チップ102を積層方向Lに貫通し、一端がベース基板101に固定された貫通電極(TSV)103と、で構成されている。複数の半導体チップ102は、貫通電極103を介して電気的に接続されている。
図4は、本発明の第二実施形態に係る半導体装置のうち、半導体チップ102Aの構成例を模式的に示す平面図である。本実施形態の半導体チップ102Aでは、少なくとも一つのサブメモリアレイ104において、貫通電極103の貫通する位置が、外周部104a(外周104c)に沿って略平行に並ぶ複数の列を構成するように分布している。その他の構成については、第一実施形態の半導体装置100、半導体チップ102の構成と同様であり、半導体装置100と対応する箇所については、形状の違いによらず、同じ符号で示している。
図5は、本発明の第三実施形態に係る半導体装置のうち、半導体チップ102Bの構成例を模式的に示す平面図である。本実施形態の半導体チップ102Bでは、外周104cに対し、近接する貫通電極103、離間する貫通電極103が、外周104cに沿って交互に並んでいる。さらに、隣接するサブメモリアレイ104の貫通電極103同士が、共通の外周104cに沿って、この近接と離間が互い違いに繰り返されるように並んでいる。その他の構成については、第一実施形態の半導体装置100、半導体チップ102の構成と同様であり、半導体装置100と対応する箇所については、形状の違いによらず、同じ符号で示している。
図6、7は、本発明の第四実施形態に係る半導体装置のうち、半導体チップ102Cの構成例を模式的に示す平面図である。本実施形態の半導体チップ102C、102Dでは、貫通電極103が、サブメモリアレイ104の外周に沿って等間隔で並んでいない。すなわち、同一サブメモリアレイ104内で隣接する貫通電極103同士の距離が、位置によって異なっている。その他の構成については、第一実施形態の半導体装置100、半導体チップ102の構成と同様であり、半導体装置100と対応する箇所については、形状の違いによらず、同じ符号で示している。
