Summary on Grant Application Form |

The study aims to assess the feasibility of using an electrode-depositable photoresist to pattern fine-pitch electrical connections onto three-dimensional surfaces.The work would involve first optimising the patterning process and then assessing its reliability on large substrates. As a case study we will assess the potential for plating some large (230x18mm) printheads which contain over 3000 piezo-electric actuators, each with a step height of 350um. For a successful process every actuator must be connected, hence the case study will provide a significant test for the technology.We will also investigate the limits of step-height versus resolution and consider some speculative methods for overcoming the Fresnel diffraction limit by the use, for exampl, of phase contrast masks.
