Description
粗化処理液の温度:30℃
スプレー圧力:0.2MPa
粗化処理液中の銅濃度:25g/l(リットル)
配線層200の上面A及び側面Bを粗化すると、配線層200の上面A及び側面Bの全体に凹凸が形成された状態となる。
図2〜図10は第1実施形態の配線基板の製造方法を示す図、図11は第1実施形態の配線基板を示す図、図12は変形例の配線基板の製造方法を示す図、図13〜図17は第1実施形態の電子部品装置を説明するための図である。
キャリア付き銅箔20は、プリプレグ10側に配置されたキャリア銅箔22とその上に配置された薄膜銅箔24とから形成される。
粗化処理液:ギ酸系水溶液
粗化処理液の温度:25℃
スプレー圧力:0.1MPa
粗化処理液中の銅濃度:15g/l(リットル)
スプレーエッチング装置(不図示)では、チャンバの上方に配置されたノズルから所定の圧力で粗化処理液を下側にスプレーし、対象物をウェットエッチングして粗化する。
(変形例の製造方法)
前述した図2(b)の構造では、キャリア付き銅箔20の剥離界面が露出しているため、後の製造工程でキャリア付き銅箔20の剥離界面に薬液が侵入するなどして剥離が発生する場合が想定される。
(第2実施形態)
図18〜図19は第2実施形態の配線基板の製造方法を示す図、図20は第2実施形態の配線基板を示す図である。第2実施形態が第1実施形態と異なる点は、第1実施形態の図2(b)の工程のキャリア付銅箔20の上にニッケル層26を形成する工程を省略することにある。
第2実施形態では、第1配線層を形成する下地層として、ニッケル層が形成されていない積層基板5を使用する。
(第3実施形態)
図22〜図24は第3実施形態の配線基板の製造方法を示す図、図25は第3実施形態の配線基板を示す図である。第3実施形態が第1実施形態と異なる点は、キャリア付き銅箔20の薄膜銅箔24の代わりにニッケル箔を使用することにある。
(第4実施形態)
図26〜図29は第4実施形態の配線基板の製造方法を示す図である。図30は第4実施形態の配線基板を示す図である。第4実施形態では、コア基板の上にセミアディティ法によって形成された配線層に対して第1実施形態と同様な粗化処理を行う。
