Abstract
【解決手段】Si基板12の一方の面から他方の面に向けて貫通電極13を形成した半導体装置10であって、他方の面16には絶縁膜20を介して矩形状の電極パッド24が設けられ、貫通電極13を構成する貫通孔21は、一方の面14側の開口部よりも他方の面16側の開口部を狭く形成し、他方の面16側の開口部の形状を矩形として電極パッド24の内側領域に配置し、電極パッド24と貫通電極13を接続したことを特徴とする。このような特徴を有する半導体装置10では、貫通孔21における一方の面14側の開口部を円形とすると良い。
【選択図】図1
Description
さらに特許文献4には、ドライエッチングによりSi基板に貫通孔を形成する際、オーバーエッチングを行う事で、貫通孔の底部の幅を貫通孔の中間部よりも広くすることで、貫通孔の形成により生じる撓みに伴う電極パッドの変形による接続不良を防止する事が記載されている。
[適用例1]Si基板の一方の面から他方の面に向けて貫通する貫通孔内に貫通電極を形成した半導体装置であって、前記他方の面には絶縁膜を介して矩形状の電極パッドが設けられ、前記貫通孔の、前記一方の面側の開口部は円形であり、前記貫通孔の前記他方の面側の開口部は矩形であり、前記一方の面側の開口部の面積よりも前記他方の面側の開口部の面積を小さくしたことを特徴とする半導体装置。
前記他方の面側の開口部の面積を前記電極パッドの面積より小さくしたことにより、他方の面側の開口部の位置がずれた場合であっても、貫通電極が電極パッドからずれるといった虞が無い。
このような傾斜面を持つことにより、貫通孔底面近傍においても絶縁膜の形成を確実なものとすることができる。
このような特徴を有することにより、一方の面の開口部の形状をいかなる形状とした場合であっても、他方の面の形状を矩形とすることが可能となる。
このような構成とすることにより、一方の面の開口部の形状をいかなる形状とした場合であっても、他方の面の形状を矩形とし、かつ電極パッドの辺と開口部の辺を平行に合わせることが可能となる。
