Abstract
A method to reduce the number and type of processing steps to achieve conductive lines in the planes of a substrate concurrently interconnecting conductor through the substrate, by forming structures in the planes of a substrate. These structures may include interconnect lines, bond pads, and other structures, and improve the performance of subsequent unique processing while simultaneously reducing the manufacturing complexity to reduce time and cost. These structures are formed by selective etching using chemical mechanical polishing, and then completed using a single fill step with a conductive material.
Claims20
A method for creating electrically or thermally conductive vias in a glass substrate, the method comprising the steps of:
- depositing a powder including copper particles on a first side of the glass substrate having holes so as to define a deposited powder in the holes;
- drying the deposited powder after the powder has been exposed to a non-polar solvent;
- and
- depositing the powder on a reverse side of the glass substrate and into the holes.
