Celebrating in 1987 thirty years of activity, predominantly in the field of electroless chemicals for the printed circuit industry, the Shipley organisation worldwide can justifiably claim to have fulfilled and to continue to fulfil the original company slogan cited above.

There are a number of organic, inorganic and hybrid inorganic waveguide materials that are currently being used for a wide variety of optical interconnect applications. Depending upon the approach, waveguide formation is performed using a combination of lithographic and/or reactive ion etch techniques. Often the processes involved with waveguide formation require unique processing conditions, hazardous process chemicals and specialized pieces of capital equipment. In addition, many of the materials have been optimized for silicon substrates but are not compatible with printed wire board (PWB) substrates and processes.
