ABSTRACT:
A process for forming planar liquid crystal matrix array chips including the steps of electro-plating a conductive material over a smoothing layer thereby filling the contact holes with conductive material or alternatively placing a photoresist over the micro circuit, electroplating over the photo resist, which is then dissolved leaving conductive posts. The smoothing material is applied around the posts and the surface then polished, made flat and reflecting electrodes attached.
