The present disclosure relates to a semiconductor device. The semiconductor device includes a semiconductor substrate, a conductive through electrode, an insulating film, a bump and a connection layer, wherein the connection layer comprises a patternable material with conductive particles. The conductive through electrode penetrates through the semiconductor substrate. The patternable material comprises photosensitive material. The photosensitive material is a photoresist or polyimide. The conductive particles comprise copper (Cu), nickel (Ni), gold (Au), or silver (Ag). The connection layer is formed by spin coating, CVD (chemical vapor deposition) process or PVD (physical vapor deposition) process. The insulating film surrounds the conductive through electrode and electrically isolates the conductive through electrode from the substrate. The bump is disposed over the conductive through electrode. The connection layer is disposed over the bump. |
