Patterned array of uniform metal microbeads |
摘要 |
The present invention provides a method for providing an array of metal microbeads on a substrate, preferably in a regular pattern of very fine, uniform size microspheres or microbeads at precise spacing or scale previously unachievable. The method of the present invention comprises the steps of providing a metal layer on a substrate that is partitioned into metal regions; heating the metal layer to a temperature sufficient to melt the metal and to permit beading of the layer into discrete microbeads. |
