Keywords:Metrigraphics? passive circuit? ERMF? additive photolithographic process?

Through the use of additive photolithographic processes, Metrigraphics has revealed that it was able to develop the Extreme Resolution Micro Flex (ERMF) ultra-miniature passive circuits and structures with traces and spaces as small as 5um.

The circuits can also be delivered in complex, high-resolution shapes and patterns for medical sensor applications including various in body and fluid sensors. The micro circuits are produced with very thin layers of sputtered metal or thicker plated metal such as gold or copper. The company also stated that its processes can achieve traces as narrow as 3um for some designs.

Metrigraphics offers both single and multilayer ERMF circuits. Multilayer circuits include additional conductive layers that are independently stacked, aligned and interconnected. Plated conductive vias connect the different layers as required. Via sizes can be down to 25um diameter.
