Fabrication Method of Double-Microlens Array Using Self-Alignment Technology

摘要

A fabrication method for double-microlens arrays with self-alignment technology (SAT) is proposed. To satisfy the tolerance of the alignment of a two-layer-lens array, we developed a new fabrication method without an alignment process. Using SAT, we achieved a brightness increase of 30% compared with the conventional single-layer microlens array.
