Description
第1実施形態の半導体装置100について、図1及び図2を参照して説明する。
さらに、半導体装置のオン抵抗を下げる為に、例えば、比較例の半導体装置900のように、コネクタの半導体チップ3のソース電極3Bと接触する部分(コンタクト部)の面積を大きくすることが考えられる
図3を用いて、第1の実施形態の変形例について説明する。図3(a)及び(b)は、第1の実施形態の変形例にかかる半導体装置100Aの構成を模式的に示す斜視図、及び第1コネクタ部を模式的に示す斜視図である。第1の実施形態の変形例は、第1の実施形態の構成に加えて、第1コネクタ部4と第2コネクタ部5とが重なり合う位置に、嵌合部を有する。
なお、第1嵌合部8及び第2嵌合部9は、例えば図3に示すような第1沿設部4C及び第3沿設部5Cに設けられた2つの丸型の凹凸であるが、第1嵌合部8及び第2嵌合部9の形状、設ける数、及び位置はこれに限定されない。
図4を用いて、第2の実施形態に係る半導体装置100Bを説明する。図4(a)及び(b)は、第2の実施形態に係る半導体装置の構成を模式的に示す斜視図及び第1コネクタ部を模式的に示す斜視図である。第2の実施形態に係る半導体装置100Bは、第1コネクタ部24及び第2コネクタ部25のそれぞれの半導体チップ3と接触する部分が、分割される点で第1の実施形態と異なる。なお、第1の実施形態と同様の構成、動作、効果等ついては説明を省略する。
図5を用いて、第2の実施形態の変形例について説明する。図5(a)及び(b)は、第2の実施形態の変形例にかかる半導体装置100Cの構成を模式的に示す斜視図及び第1コネクタ部を模式的に示す斜視図である。第2の実施形態の変形例は、第1コネクタ部及び第2コネクタ部が複数設けられることで、半導体チップ3と接触するコンタクト部が分割される点で第2の実施形態と異なる。なお、第1の実施形態と同様の構成、動作、効果等ついては説明を省略する。
