Substrate-based thin-film circuits

July 23, 2014
A new substrate-based additive fabrication technique eliminates the sloping caused during traditional chemical etching, which results in performance variations and yield issues.
A new substrate-based additive fabrication technique eliminates the sloping caused during traditional chemical etching, which results in performance variations and yield issues. The technique creates substrate-based, ultraminiaturized circuits with properties that include circuit lines and spaces as small as 10 μm, vias as small as 25 μm in diameter, plated through-holes to ground with “metal-backed” ceramics, and multilayer devices with up to six metal layers.

The process defines circuit lines by electroplating or sputtering metal traces onto either a rigid substrate in a single layer device or onto a polyimide layer in a multilayer device for extreme uniformity in geometries as well as the ability to deposit exactly the desired amount of metal in exactly the desired location.
