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.

A method for forming a high efficiency electro-optics device, comprising:
- providing a die carrier;
- forming a light reflective layer upon a surface of said die carrier to change an emitted light to a reflected light, wherein said light reflective layer has a pattern for diverging said emitted light;
- forming a transparent layer upon said light reflective layer;
- fixing an electro-optics cell on said transparent layer;
- and
- electrically connecting a first electrode and a second electrode of said electro-optics cell respectively to the said die carrier and a lead frame having an opposite polarity with respect to said first electrode and said second electrode.
