Description
図8は従来の半導体装置における電極パッド部分の平面図である。
半導体素子が形成されている半導体チップ1において、外周部の電極パッド2の配置が二段に交互に並んだ接続構造、つまり電極パッド2が1つずつ千鳥状に配置された構成で、電極パッド2上には金属突起物28が形成されている。金属突起物28は、熱圧着によって、配線基板の配線6あるいは配線7と接続され、半導体チップ1が配線基板に実装されている。この構造により、電極パッドを一段に実装した時よりも高密度実装が可能となっている。また、電極パッドを大きくとることができ、実装性を向上させている(例えば、特許文献1参照)。
請求項3記載の半導体装置は、複数の電極パッドがチップ端の外周から内側に向かって平面的に複数段配列された半導体チップを、前記電極パッドと金属突起物を介して接続される配線を配置したテープ配線基板に実装して成る半導体装置であって、最内周から2段目以降外周に配列された任意の電極パッド間にあらかじめ定められた所定の間隔を設け、最外周から2段目以降内側に配列された電極パッドと接続される配線のうちの隣接して配線される複数の配線が前記間隔に形成され、最外周に配置された電極パッドの方が最外周から2段目以降内側の電極パッドよりパッドサイズが大きいことを特徴とする。
請求項4記載の半導体装置は、複数の電極パッドがチップ端の外周から内側に向かって平面的に2段配列された半導体チップを、前記電極パッドと金属突起物を介して接続される配線を配置したテープ配線基板に実装して成る半導体装置であって、外周側に配列された任意の電極パッド間にあらかじめ定められた所定の間隔を設け、内側に配列された電極パッドと接続される配線のうちの隣接して配線される複数の配線が前記間隔に形成され、外周側に配列された電極パッドの方が内側に配列された電極パッドよりパッドサイズが大きいことを特徴とする。
