发明名称 Silicon Chip Having Through Via and Method for Making the Same
摘要 The present invention relates to a silicon chip including a silicon substrate, a passivation layer, at least one electrical device and at least one through via. The passivation layer is disposed on a first surface of the silicon substrate. The electrical device is disposed in the silicon substrate, and exposed to a second surface of the silicon substrate. The through via includes a barrier layer and a conductor, and penetrates the silicon substrate and the passivation layer. A first end of the through via is exposed to the surface of the passivation layer, and a second end of the through via connects the electrical device. When a redistribution layer is formed on the surface of the passivation layer, the redistribution layer will not contact the silicon substrate, thus avoiding a short circuit.
