Description
前記半導体基板の前記第1の面に作り込まれた集積回路と、
前記半導体基板の前記第1の面に形成された電極と、
を有し、
前記複数の側面の少なくとも1つは、前記第1及び第2の面に対して傾斜面であり、
前記傾斜面に溝が形成され、
前記溝は、前記第1及び第2の面と平行な平面に対して交差する方向に延びるとともに、前記第1及び第2の面に直交する平面に対して交差する方向に延びてなる。本発明によれば、溝を形成することで、半導体基板の側面に凹凸を形成することができる。凹凸の形成によって、放熱性の向上や接着剤との密着性の向上が得られる。また、溝は、半導体基板の割れやすい方向とは交差して延びるので、半導体チップが割れやすくならない。
(2)この半導体チップにおいて、
前記第1の面と前記傾斜面とのなす角は、前記半導体基板の内部側において鋭角をなしてもよい。
(3)この半導体チップにおいて、
前記第1の面と前記傾斜面とのなす角は、前記半導体基板の内部側において鈍角をなしてもよい。
(4)この半導体チップにおいて、
隣接する一対の前記側面が、第1及び第2の前記傾斜面であってもよい。
(5)この半導体チップにおいて、
前記第1の面と前記第1の傾斜面とのなす角は、前記半導体基板の内部側において鋭角をなし、
前記第1の面と前記第2の傾斜面とのなす角は、前記半導体基板の内部側において鈍角をなしてもよい。
(6)この半導体チップにおいて、
前記第2の面は、矩形をなし、
前記第2の面に、前記矩形の全ての辺に交差する方向に延びる溝が形成されていてもよい。
(7)本発明に係る半導体装置は、上記半導体チップと、
配線パターンが形成されてなる基板と、
を有し、
前記半導体チップの前記電極と、前記配線パターンとが電気的に接続されてなる。
(8)本発明に係る回路基板は、上記半導体装置が実装されてなる。
(9)本発明に係る電子機器は、上記半導体装置を有する。
図1は、本発明の第1の実施の形態に係る半導体装置を説明する図である。半導体装置は、半導体チップ10を有する。図2は、本発明の第1の実施の形態に係る半導体チップの概略を示す斜視図であり、図3は、本発明の第1の実施の形態に係る半導体チップの概略を示す平面図である。
図4は、本発明の第2の実施の形態に係る半導体装置を説明する図である。半導体装置は、半導体チップ40を有する。図5は、本発明の第2の実施の形態に係る半導体チップの概略を示す上面図であり、図6は、本発明の第2の実施の形態に係る半導体チップの概略を示す底面図である。
図7〜図10は、本発明の実施の形態に係る半導体チップの変形例を説明する平面図である。これらの変形例は、半導体チップの外形についての変形例である。以下に説明することを除き、各変形例には上述した実施の形態の内容が該当する。
