    • A wafer level packaging cap and a manufacturing method thereof are provided to realize a patterning in a deep hollow unit by spray-coating an upper surface and a lower surface of the hollow unit with a metal material and patterning them through a lift-off process. A hollow unit(20a) providing a space where a device is accommodated is formed on a lower surface of a cap substrate(20). The cap substrate has a first passing hole and is coupled to a device wafer(4). The first passing hole passes through the position where the hollow hole is prepared. A dielectric(22) is prepared on an upper surface of the cap substrate and has a second passing hole corresponding to the first passing hole. A cap pad(24) is prepared on an upper portion of the dielectric. A metal line(26) is formed on the lower surface of the cap substrate to be corresponding to plural device pads(46) electrically connected to the device. The metal line and the cap pad are electrically connected in the first and second passing holes.
    • 提供晶片级封装盖及其制造方法,通过用金属材料喷涂中空单元的上表面和下表面并通过剥离工艺将其图案化,从而在深空心单元中实现图案化。 在盖基板(20)的下表面上形成提供装置的空间的中空单元(20a)。 盖衬底具有第一通孔并且耦合到器件晶片(4)。 第一通孔穿过中空孔准备的位置。 在盖基板的上表面上制备电介质(22),并具有与第一通孔相对应的第二通孔。 在电介质的上部制备帽垫(24)。 金属线(26)形成在盖基板的下表面上,以对应于与设备电连接的多个器件焊盘(46)。 金属线和盖垫在第一和第二通孔中电连接。
