具硅穿孔连续型态的晶圆级晶片尺寸封装构造及制造方法
摘要：
本发明公开了一种具硅穿孔连续型态的晶圆级晶片尺寸封装构造及制造方法。该封装构造，主要包含装置晶片、贴合于装置晶片的载体晶片、保护盖片以及硅穿孔结构。一金属互连平行垫组合嵌埋于装置晶片中，偏移垫设置于装置晶片并连接至金属互连平行垫组合。间隔导体凸块接合于偏移垫上。间隔黏合层形成于装置晶片上并包覆间隔导体凸块。保护盖片压贴于间隔黏合层上。硅穿孔结构包含一贯穿孔以及一孔金属层，贯穿孔微偏心地对准偏移垫连续贯穿载体晶片与装置晶片，孔金属层形成于贯穿孔内并连接偏移垫，贯穿孔非中心对准于间隔导体凸块。保护层形成于载体晶片并覆盖贯穿孔。因此，借由偏移垫上间隔导体凸块，以确保硅穿孔结构的连续型态。
摘要（英）：

A wafer level chip scale package (WLCSP) has a device chip, a carrier chip, an offset pad, a conductive spacing bump and a through hole via (THV). The device chip is attached to the carrier chip. The offset pad is disposed on a first surface of the device chip. The conductive spacing bump is formed on the offset pad. The through hole via includes a through hole and a hole metal layer. The through hole penetrates through the carrier chip and the device chip, and the hole metal layer is formed in the through hole and in contact with the offset pad.
