20140159182 | SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING A SEMICONDUCTOR DEVICE HAVING AN UNDULATING REFLECTIVE SURFACE OF AN ELECTRODE - A method for manufacturing a semiconductor device includes providing a substrate and a back electrode disposed between the substrate and an active semiconductor layer. The back electrode has a reflective layer that is reflective to at least one wavelength of light and includes a reflective surface having an undulating profile that includes peaks and valleys. The method includes depositing a filler layer onto the reflective layer of the back electrode. The filler layer at least partially fills one or more of the valleys of the reflective surface. The filler layer is transmissive to the at least one wavelength of light such that the at least one wavelength of light can pass through the filler layer to the reflective layer. The method includes depositing the active semiconductor layer onto the filler layer such that the filler layer and the back electrode are disposed between the substrate and the active semiconductor layer. | 06-12-2014 |
