Abstract
The present invention relates to a method of aligning comprising providing a support, applying a transparent layer, patterning at least the transparent layer to produce a pattern and an alignment feature capable of scattering light, illuminating the support and the transparent layer with oblique lighting, providing an analysis system capable of sensing scattered light from the alignment feature and referencing, sensing the scattered light from the alignment feature; referencing the scattered light from the alignment feature to a position on said support; and aligning a second operation to the position.
Claims36
A method of aligning layers in a multilayer product comprising
- providing a support,
- forming a transparent first patterned layer having areas of transparent material and areas without material where the first patterned layer includes an alignment feature capable of scattering light,
- illuminating said support, and said transparent first patterned layer with oblique lighting,
- providing an analysis system capable of sensing scattered light from said alignment feature and referencing,
- sensing said scattered light from said alignment feature;
- referencing said scattered light from said alignment feature to a position on said support;
- and
- forming a second patterned layer aligned with the first patterned layer.
