20080197369 | Double flip semiconductor device and method for fabrication - A double flip-chip semiconductor device formed by a double flip fabrication process. Epitaxial layers are grown on a substrate in the normal fashion with the n-type layers grown first and the p-type layers grown subsequently. The chip is flipped a first time and mounted to a sacrificial layer. The original substrate is removed, exposing the n-type layer, and various additional layers and treatments are added to the device. Because the n-type layer is exposed during fabrication, the layer may be processed in various ways including adding a reflective element, texturing the surface or adding microstructures to the layer to improve light extraction. The chip is flipped a second time and mounted to a support element. The sacrificial layer is then removed and additional layers and treatment are added to the device. The finished device features a configuration in which the layers maintain the same orientation with respect to the support element that they had with the original substrate on which they were grown. Processing the n-type layers, rather than the p-type layers as in a single flip process, provides greater design flexibility when selecting features to add to the device. Thus, previously unavailable processes and reflective elements may be utilized, enhancing the external quantum efficiency of the device. | 08-21-2008 |
