    • A white-light LED chip and a fabrication method thereof are provided. The white-light LED chip comprises a blue-light LED chip and a phosphor layer directly disposed on a top surface of the blue-light LED chip. The method comprises providing a plurality of blue-light LED chips attached to a substrate, wherein at least one contact pad is formed on the top surface of each blue-light LED chip. A protective layer is formed on the contact pad. A phosphor layer is formed on the top surface of the blue-light LED chip by a molding process, exposing the contact pad. Finally, the protective layer and the substrate are removed from the blue-light LED chip to form a white-light LED chip.
    • 提供了一种白光LED芯片及其制造方法。 白光LED芯片包括蓝光LED芯片和直接设置在蓝光LED芯片的顶表面上的荧光体层。 该方法包括提供附着在基板上的多个蓝光LED芯片,其中至少一个接触焊盘形成在每个蓝光LED芯片的顶表面上。 在接触垫上形成保护层。 通过成型工艺在蓝光LED芯片的顶表面上形成荧光体层,露出接触垫。 最后,从蓝光LED芯片去除保护层和基板,以形成白光LED芯片。
