Abstract
【解決手段】ダイパッド13の周りに複数のインナーリード14が設けられている。ダイパッド13と複数のインナーリード14との間の領域に、接地されたGNDリード16が設けられている。半導体チップ17と複数のインナーリード14は、複数のワイヤー21によりそれぞれ接続されている。半導体チップ17とGNDリード16はGNDワイヤー22により接続されている。GNDワイヤー22は複数のワイヤー21の間に配置されている。隣接するインナーリード14の先端の間隔が0.2mm以下である。
【選択図】図4
Description
図1は、本発明の実施の形態1に係る半導体装置を示す平面図であり、図2はその側面図である。半導体チップ(後述)をモールド樹脂で封止したパッケージ本体11から複数のアウターリード12が出ている。
図9は、本発明の実施の形態2に係る半導体装置の要部を拡大した平面図である。実施の形態1では2本の差動信号用インナーリード14aの間隔を広げたのに対し、本実施の形態では、2個の差動信号用パッド18aの間隔を、複数のパッド18の最小間隔よりも広くしている。
図10は、本発明の実施の形態3に係る半導体装置のパッケージ本体の内部を示す平面図であり、図11は図10の要部を拡大した平面図である。本実施の形態3では2本の差動信号用インナーリード14aの間隔WAを、差動信号用インナーリード14aがアウターリードと連続する部分の間隔WBよりも広くしている。例えば、間隔WAを250μm、間隔WBを220μmとする。これにより、特性インピーダンスの不整合を小さくして信号の伝達特性が劣化するのを防ぐことができる。そして、全てのインナーリードの間隔を広くしているわけではないので、半導体装置の大型化を抑制することができる。
