比較例4に係る長方形パッケージ100Aに搭載する半導体チップ20の半導体ウェハ200上の配置例は、図6に示すように表される。また、比較例4に係る長方形パッケージ100Aの模式的平面構成は、図7に示すように表される。比較例4に係る長方形パッケージ100Aに搭載される半導体チップ20は、長方形形状を備えることから、図6に示すように、半導体ウェハ200からスクライビング工程経て切り出すことができる。
第1の実施の形態に係るパッケージ100の模式的平面構成は、図8に示すように表され、第1の実施の形態に係るパッケージ100において、コーナー部分における拡大された模式的平面構成は、図9に示すように表される。
第1の実施の形態の変形例に係るパッケージ100の模式的平面構成は、図10に示すように表される。ここで、複数のリードフレーム12の先端部の軌跡は、半導体チップ20の辺に対して、鋭角な角度を有し緩和されている。その他の構成は、第1の実施の形態と同様である。
第2の実施の形態に係る長方形パッケージ100に搭載する半導体チップの半導体ウェハ200上の配置例は、図12に示すように表される。第2の実施の形態に係る長方形パッケージ100に搭載される半導体チップ20は、菱形形状を備えることから、図12に示すように、半導体ウェハ200からスクライビング工程を経て切り出すことができる。
上記のように、実施の形態によって記載したが、この開示の一部をなす論述および図面は例示的なものであり、この発明を限定するものであると理解すべきではない。この開示から当業者には様々な代替実施の形態、実施例および運用技術が明らかとなろう。
