Abstract
A method for packaging an electro-optics device is disclosed. A transparent material is added between the die carrier and the electro-optics device, so that the light emitted from the backside of the electro-optics device can be extracted. Furthermore, a light reflective layer is formed on the die carrier, and a pattern of the light reflective layer is designed to prevent the light from being reflected to the active layer, the reflecting decreasing light-emitting efficiency again.
