Outline of Final Research Achievements

We develop elemental technologies to integrate and mount integrated circuits and detectors using printing technology. Detectors are becoming narrower in pitch and more multi-channel, and there is a growing demand to mount application-specific integrated circuits (ASICs) near the detector. Integrated circuits are also manufactured using fine processes, and miniaturization of mounting technology has become indispensable. In this study, the following were conducted. 1) Verification of printing parameters to produce ultra-fine printed wiring with a wiring width/line spacing = 50μm/15μm. 2) Printed wiring was used to mount sensors for the purpose of fabricating radiation detectors. 3) Verification of the principle of integrated circuit stacking technology using short-range wireless communication by printing inductors on integrated circuits was conducted.

Academic Significance and Societal Importance of the Research Achievements

本研究における学術的意義・社会的意義としては、学術分野において、本研究は微細化が進む放射線検出器・集積回路の実装に関して、プリント基板の実装パッドなどパッケージやワイヤーボンディングを用いた場合よりも短距離で配線が可能であり、ノイズの観点からも有効である。このようにパッケージ化やワイヤーボンディングといった実装技術による制約で実現不可能だったフレキシビリティのある新しい検出器の開発が実現可能となる成果である。この成果は社会的産業的観点からも微細化やウェアラブル化が進むエレクトロニクス分野に対して有用な技術となる。
