Definitions
- the present invention is based on the priority claim of Japanese Patent Application: Japanese Patent Application No. 2008-190100 (filed on July 23, 2008), the entire description of which is incorporated herein by reference. Shall.
- the present invention relates to a semiconductor device and a manufacturing method thereof.

Description
本発明は、日本国特許出願:特願2008-190100号(2008年7月23日出願)の優先権主張に基づくものであり、同出願の全記載内容は引用をもって本書に組み込み記載されているものとする。
本発明は、半導体装置及びその製造方法に関する。特に、半導体素子をコアレス配線基板に内蔵させ、樹脂等の絶縁層で覆い、その上に多層の配線層と絶縁層を積層した半導体装置及びその製造方法に関する。
半導体パッケージのインターポーザ基板にコア層を持ったビルドアップ基板を用いた場合には、コア基板の貫通スルーホール(TH)・配線幅がビルドアップ層のビア径・配線幅に比べて数倍大きいため、そのスケール差がパッケージ基板の高速化・高密度微細配線化の障害となる。一方、配線層にコア層を用いないコアレス基板は、ビルドアップ基板に対して、高速化・高密度微細配線化が可能であるが、支持体上に逐次的に配線体を積層する構造のため、層数が増えると歩留まりが層数の階乗で劣化することが知られている。狭ピッチ、多ピンの半導体素子と接続するコアレス基板は、多層化が必須であるため、高歩留まりで多層化を実現するコアレス基板が必要不可欠であった。

132 導体回路(配線層)
1回以上繰り返す第二の配線体形成工程(図12(e)、図18(e))のうち、少なくとも1回の第二の配線体形成工程が、当該工程より前の工程で形成したビア(16、30)の断面形状より拡大された断面形状を有するビア(19、22)を新たに形成する工程を含む。
図1は、本発明の実施形態1による半導体装置を示す断面図である。図1の半導体装置12は、半導体素子13の側面と電極端子14を有する面の少なくとも一部が絶縁層A(15)に接しており、電極端子14の上面側に、電極端子14と半導体装置12の外部接続端子である配線C(23)とを電気的に接続するビアA(16)、配線A(17)、絶縁層B(18)、ビアB(19)、配線B(20)、絶縁層C(21)、ビアC(22)が設けられている。また、半導体素子13の電極端子14が設けられた面の反対面が、絶縁層A(15)から露出している構造である。
図21は、実施形態1の変形例1による半導体装置の断面図である。図21は、図1と比べると、絶縁層B(18A)、絶縁層C(21A)の膜厚を絶縁層A(15)の膜厚とほぼ同一にして薄くしている。また、半導体素子13Aの厚さも図1より薄くしている。従って、半導体装置12全体の薄型化が可能である。配線B(20)の配線断面形状は、配線A(17)より拡大させているが、配線C(23A)の配線断面形状は、配線B(20)とほぼ同一にしている。半導体素子13Aの電極端子14のピッチに合わせて半導体素子13Aに対する最近接層である配線層17の配線を狭いピッチで配線すると共に、最近接層17の配線をファンアウト層として、最近接層より外部接続端子23側の配線層、ビアの配線ピッチを拡大して配線できるように、半導体素子13Aから引き出した配線の一部を半導体素子13Aより外側でビアB(19A)へ接続している。従って、配線A(17)より外部接続端子23A側の配線層(20、23A)では配線ピッチを広げて、配線断面形状を拡大して配線できる。従って、電極端子14が狭ピッチであるにも係らず、第一の電極端子14に対する最近接層である配線層17以外の配線層の配線断面形状を拡大して配線できる。ちなみに、配線層17の最小配線幅、最小配線間隔が10μm、厚さは10μmであるのに対して、配線層20、配線層23の最小配線幅、最小配線間隔を50μm、厚さ15μmとすることができる。また、絶縁層の膜厚を薄くしているので、ビアB(19A)、ビアC(22A)のビア断面形状は、アスペクト比が崩れないようにビアA(16)とほぼ同一形状にしている。すなわち、この変形例では、半導体素子13Aに対する最近接層の配線層17の配線断面形状を他の配線層より小さくすることにより、薄型でかつ、歩留まりよく製造が可能な半導体素子内蔵コアレス基板が実現できる。
図22は、実施形態1の変形例2による半導体装置の断面図である。図22は、図1と比べると、配線B(20A)、配線C(23B)の配線断面形状を配線A(17)とほぼ同一にしている。一般に、狭ピッチで微細な配線を形成するためには、高精度の配線形成工程が必要になるため、高コストになりやすい。しかし、配線層によって配線形成工程を変えない方が、安定して低コストで製造できる場合は、図22のように全ての配線層の配線に微細な配線が可能な配線層を用いることもできる。なお、電極端子14のピッチに合わせて微細な配線を形成しなければならない配線A(17)に対して、配線B(20A)、配線C(23B)の配線に余裕がある場合は、開いたスペースをグランド配線で覆うこともできる。ただし、配線B(20A)、配線C(23B)の設計ルール上の最小配線幅、最小配線間隔は、配線A(17)と同一である。また、配線B(20A)、配線C(23B)の配線の厚さは、配線A(17)と同一である。
図23は、実施形態1の変形例2による半導体装置を示す断面図である。図23では、図1に対して、半導体装置12の最上面に、配線C(23)の一部を開口するようにソルダーレジスト24が設けられている。ソルダーレジスト24は、配線C(23)の一部を露出させ残部を覆うよう設けられている。この変形例では、ソルダーレジスト23の材料として、感光性レジストインクを用いた。ソルダーレジスト24から開口した表面には、金、銀、銅、錫及び半田材料からなる群から選ばれる少なくとも1種の金属又は合金で形成されていてもよい。本実施形態では、厚み3μmのニッケルおよび0.5μmの金を順に積層した。
また、図2に示すように、半導体素子13の電極端子14の反対面に接着層26が設けられていても構わない。その場合、接着層26が半導体素子13への汚染防止として機能する。また、図3に示すように、接着層26は、半導体素子13の電極端子14の反対面のみに限らず、絶縁層A(15)と接するように設けられていても構わない。
図4は、本発明の実施形態2による半導体装置を示す断面図である。図4の半導体装置12は、半導体素子13の電極端子14を有する面の少なくとも一部が絶縁層A(15)に接しており、半導体素子13の側面が絶縁層D(29)に接しており、電極端子14の上面側に、電極端子14と半導体装置12の外部接続端子である配線C(23)とを電気的に接続するビアA(16)、配線A(17)、絶縁層B(18)、ビアB(19)、配線B(20)、絶縁層C(21)、ビアC(22)が設けられている。また、配線C(23)の一部を開口するようにソルダーレジスト24が設けられている。また、半導体素子13の電極端子14が設けられた面の反対面が、絶縁層D(29)から露出している構造である。
図6は、本発明の実施形態3による半導体装置を示す断面図である。図6の半導体装置12は、半導体素子13の側面と電極端子14を有する面の少なくとも一部が絶縁層A(15)に接しており、電極端子14の上面側に、電極端子14と半導体装置12の外部接続端子である配線C(23)とを電気的に接続する金属ポスト30、配線A(17)、絶縁層B(18)、ビアB(19)、配線B(20)、絶縁層C(21)、ビアC(22)が設けられている。また、配線C(23)の一部を開口するようにソルダーレジスト24が設けられている。また、半導体素子13の電極端子14が設けられた面の反対面が、絶縁層A(15)から露出している構造である。
図7は、本発明の実施形態4による半導体装置を示す断面図である。図7の半導体装置12は、半導体素子13の側面と電極端子14を有する面の少なくとも一部が絶縁層A(15)に接しており、電極端子14の上面側に、電極端子14と半導体装置12の外部接続端子である配線C(23)とを電気的に接続するビアA(16)、配線A(17)、絶縁層B(18)、ビアB(19)、配線B(20)、絶縁層C(21)、ビアC(22)が設けられている。また、配線C(23)の一部を開口するようにソルダーレジスト24が設けられている。また、半導体素子13の電極端子14が設けられた面の反対面に支持体25が設けられている構造である。図7では、層数が3層であるが、それに限るものではなく、複数層であれば何層でも構わない。本実施形態では、配線層3層、絶縁層3層とした。
