In one embodiment the CMP is only used to separate the active, thin film layer into sub-cells, with scribing still being used to achieve sub-cell separation in conductive layers above and below the active, thin film layer. Also, the active layer may be placed over a series of protrusions so that the CMP removes the active layer that is over the protrusion, while leaving intact the flat, planar portions of the active layer. In this way, the removed active layer, from over the protrusions then becomes the division between sub-cells in the active layer. | 01-22-2015 |
