Abstract

A 'crescent-shaped' binding alignment mark, more applicable to the self-alignment than reported 'tear-drop/elliptical hole' pattern, has been designed and comparatively studied with other possible alignment marks. In order to further apply this novel design to micro-parts with positive and negative poles on the binding sites, a modified 'crescent-shaped' pattern with an insulated space area, defined as 'crescent-shaped/interval' for self-alignment of micro-parts with two poles has been therefore proposed and discussed. The fabrication process using micromachining has been studied and both the substrates and micro-parts with alignment marks have been fabricated for next self-alignment verification.
