Description
前記樹脂成分が、エポキシ樹脂と、活性エステル樹脂と、芳香族ポリアミド樹脂とを含む、樹脂組成物が提供される。
本発明の樹脂組成物は、樹脂成分と、誘電体フィラーとを含む。そして、この樹脂成分は、エポキシ樹脂と、活性エステル樹脂と、芳香族ポリアミド樹脂とを含む。このように、エポキシ樹脂、活性エステル樹脂及び芳香族ポリアミド樹脂を誘電体フィラーと共に含む樹脂組成物を、キャパシタの誘電体層として用いることで、優れた回路密着性を確保しながら、高温高湿下におけるキャパシタンス低下ないし誘電率低下を抑制することができる。すなわち、本発明の樹脂組成物を含む誘電体層は本来的に静電容量が高く、高温高湿下においてもその高い静電容量が低下しにくい。また、本発明の樹脂組成物を含む誘電体層は、高温高湿下においても回路構成成分(典型的にはCu等の金属)のマイグレーションが起こりにくく、それ故、層間絶縁性を長期にわたって保持することができる。したがって、誘電体層は、高温高湿下で誘電率が低下しにくく、それ故、高温高湿下におけるキャパシタンスが低下しにくくなる。そうでありながら、本発明の樹脂組成物を含む誘電体層は回路密着性にも優れており、キャパシタにおける回路剥がれが起こりにくい。
本発明の樹脂組成物は樹脂付銅箔の樹脂として用いられるのが好ましい。樹脂付銅箔における樹脂組成物は、2枚の樹脂付銅箔を樹脂組成物が互いに向かい合うように積層して誘電体層を形成させる観点から、半硬化されているのが好ましい。予め樹脂付銅箔の形態とすることで、樹脂層ないし誘電体層を別途形成することなく、キャパシタ素子やキャパシタ内蔵プリント配線板の製造を効率良く行うことができる。すなわち、本発明の好ましい態様によれば、銅箔と、銅箔の少なくとも一方の面に設けられた樹脂組成物とを含む、樹脂付銅箔が提供される。典型的には、樹脂組成物は樹脂層の形態であって、樹脂組成物を、銅箔に乾燥後の樹脂層の厚さが所定のものとなるようにグラビアコート方式で塗工し乾燥させ、樹脂付銅箔を得る。この塗工の方式については任意であるが、グラビアコート方式の他、ダイコート方式、ナイフコート方式等を採用することができる。その他、ドクターブレードやバーコータ等を使用して塗工することも可能である。
本発明の樹脂組成物は硬化されて誘電体層とされるのが好ましい。すなわち、本発明の好ましい態様によれば、本発明の樹脂組成物が硬化された層である、誘電体層が提供される。樹脂組成物の硬化は公知の手法に基づき行えばよいが、熱間真空プレスにより行うのが好ましい。誘電体層の厚さは、所望の静電容量を確保できる限り特に限定されないが、好ましくは0.2~30μmであり、より好ましくは0.5~20μm、さらに好ましくは1~8μm、最も好ましくは2~6μmである。これらの範囲内の厚さであると、高い静電容量を実現しやすい、樹脂組成物の塗布により樹脂層の形成がしやすい、銅箔との間で十分な密着性を確保しやすいといった利点がある。
本発明の樹脂組成物ないしそれを含む誘電体層は銅張積層板に適用されるのが好ましい。すなわち、本発明の好ましい態様によれば、第一銅箔と、上述した誘電体層と、第二銅箔とを順に備えた、銅張積層板が提供される。銅張積層板の形態とすることで、本発明の樹脂組成物を誘電体層として含むキャパシタ素子やキャパシタ内蔵プリント配線板を望ましく作製することができる。銅張積層板の作製方法は特に限定されないが、例えば、2枚の上述した樹脂付銅箔を樹脂層が互いに向かい合うように積層して高温で真空プレスすることにより銅張積層板を製造することができる。
本発明の樹脂組成物ないしそれを含む誘電体層はキャパシタ素子に組み込まれるのが好ましい。すなわち、本発明の好ましい態様によれば、上述した誘電体層を有する、キャパシタ素子が提供される。キャパシタ素子の構成は特に限定されず、公知の構成が採用可能である。特に好ましい形態は、キャパシタないしその誘電体層がプリント配線板の内層部分として組み込まれた、キャパシタ内蔵プリント配線板である。すなわち、本発明の特に好ましい態様によれば、上述した誘電体層を有する、キャパシタ内蔵プリント配線板が提供される。特に、本発明の樹脂付銅箔を用いることで、キャパシタ素子やキャパシタ内蔵プリント配線板を公知の手法に基づき効率良く製造することができる。
