Description
本発明の実施形態1に係る半導体パッケージの概要について、図1を参照しながら詳細に説明する。図1は、本発明の一実施形態に係る半導体パッケージの断面模式図である。
図1に示すように、半導体パッケージ10は、支持基材100、接着層110、半導体装置120、第1樹脂絶縁層130、配線140、第2樹脂絶縁層150、及びはんだボール160を有する。
図1に示す半導体パッケージ10に含まれる各部材(各層)の材料について詳細に説明する。
図2乃至図23を用いて、本発明の実施形態1に係る半導体パッケージ10の製造方法を説明する。図2乃至図23において、図1に示す要素と同じ要素には同一の符号を付した。ここで、支持基材100としてステンレス基材、第1樹脂絶縁層130としてエポキシ系樹脂、第1導電層142及び第2導電層144としてCu、はんだボール160として以上に述べたSn合金を使用して半導体パッケージを作製する製造方法について説明する。
本発明の実施形態2に係る半導体パッケージの概要について、図24を参照しながら詳細に説明する。図24は、本発明の一実施形態に係る半導体パッケージの断面模式図である。
実施形態2に係る半導体パッケージ20は、実施形態1の半導体パッケージ10と類似しているが、アライメントマーカ114が接着層110に設けられた開口部で実現されている点において、半導体パッケージ10と相違する。なお、半導体パッケージ20では、支持基材100には凹部が形成されていない。ただし、この構造に半導体パッケージ10と同様に支持基材100に凹部を設けて、補助的なアライメントマーカを形成してもよい。半導体パッケージ20のその他の部材については、半導体パッケージ10と同様であるので、ここでは詳しい説明を省略する。
図25乃至図29を用いて、本発明の実施形態2に係る半導体パッケージ20の製造方法を説明する。図25乃至図29において、図24に示す要素と同じ要素には同一の符号を付した。ここで、半導体パッケージ10と同様に、支持基材100としてステンレス基材、第1樹脂絶縁層130としてエポキシ系樹脂、第1導電層142及び第2導電層144としてCu、はんだボール160として上述したSn合金を使用して半導体パッケージを作製する製造方法について説明する。
