  • Patent number: 6717711
    Abstract: A forming method and a structure of a high efficiency electro-optics device are disclosed. In the present invention, the cell-fixing surface between the die carrier and the electro-optics cell is decreased to increase the light emitting and absorbing regions of the electro-optics device. Thus, the operating efficiency and the sensitivity of the electro-optics device is increased substantially. Especially, the present invention has the advantage of fully showing the efficacy of device using the transparent substrate. Furthermore, when the electro-optics cell is fixing on the cell-fixing surface by utilizing the eutectic or metal-melting bonding method, a result of self-alignment can be achieved. Thus, the accuracy of the packaging device is increased substantially, thereby reducing the loss caused by the failure of poor cell-fixing while in mass production and meanwhile increasing the accuracy of fixing cell. Therefore, the present technology is quite suitable for use in the packaging of high precision.
