Abstract
Description
1.第1の実施の形態(特性変動を抑制した貫通電極を形成する例)
2.第2の実施の形態(部品内蔵ガラス基板を形成する例)
<特性変動を抑制した貫通電極の形成>
<Via-Firstプロセス>
まず、図1を参照して、一般的なVia-Firstプロセスによる貫通電極付ガラス基板の作成方法の詳細について説明する。尚、図1においては、工程に対応したガラス基板Gの状態a乃至gが示されており、それぞれガラス基板Gの側面断面であり、図1中の上方の面がガラス基板Gの表面であり、図中の下方の面がガラス基板Gの裏面である。
次に、図2のフローチャートを参照して、本技術を適用した配線基板製造処理について説明する。
以上においては、LCD用アレイ基板の例について説明してきたが、ガラス基板を用いるものであれば、他の基板にも適用することができ、例えば、有機EL(Electro Luminescence)ディスプレイパネルに適用することもできる。
<部品内蔵ガラス基板の形成>
以上においては、特性変動を抑制した貫通電極を形成する例について説明してきたが、貫通電極を形成する技術を応用することで、ガラス基板にキャビティや大型の貫通孔を形成し、大型の装置や、耐熱性を備えない装置などを含めた部品をガラス基板内に内蔵する部品内蔵ガラス基板を形成するようにしても良い。
本技術を適用した部品内蔵ガラス基板は、例えば、図5で示されるようなものである。尚、図5の上部には、部品内蔵ガラス基板101の分解図が示されており、下部には、部品内蔵ガラス基板101の側面断面図が示されている。
次に、図6のフローチャートを参照して、貫通孔151、キャビティ152、および貫通電極173が形成された部品内蔵ガラス基板の製造処理について説明する。
次に、光硬化性樹脂を用いた基板同士の積層方法について説明する。本技術においては接着剤としてUV硬化樹脂を用いている。配線基板112と部品実装基板111との接着を行う際、可動部をもつMEMS(Micro Electro Mechanical Systems)素子チップなど、接着剤と接触しないことが必要な受動部品133も実装されている場合がある。
次に、図9のフローチャートを参照して、積層処理について説明する。
本技術においては、配線基板112の貫通孔151およびキャビティ152の開口の際、同時に様々な形状を形成できるため、その他の目的を持った構成を形成するようにしてもよく、例えば、部品冷却用のマイクロ流路を基板内に内蔵させるようにしてもよい。
本技術による部品内蔵ガラス基板101には、配線、貫通電極、およびキャビティ等を用いることで、電磁シールド構造(金属シールド構造)を形成させることができる。
本技術においては、熱負荷に弱い部品などを内蔵した状態で部品内蔵ガラス基板101を実現することができるため、電子機器に必要なすべての部品を基板内に内蔵することが可能となる。
本技術による部品内蔵ガラス基板101は、立体構造を形成したガラス基板を複数貼り合せて構成されている。特に、感光性ガラスを用いることで、この立体形状を自由に形成することが可能である。そこで、この特徴を活かして、感光性ガラスからなるレンズ構造を形成するようにしてもよい。
