  • Publication number: 20160093555
    Abstract: The TSV technology has been popular as one of stacking technologies of a plurality of semiconductor chips. It has however been revealed by the present inventors that when TSV is formed using a so-called first via process, via middle process, front-via via last process, or the like, there is a possibility of defects such as gate breakdown occurring due to electrostatic breakdown in the subsequent process. In order to overcome the above problem, the present invention provides a method of manufacturing a semiconductor integrated circuit device, in which a through via electrode is formed by forming a hole in a semiconductor substrate, forming an insulating member in the hole, and burying a conductive member in the resulting hole while covering a portion of the hole except for the bottom portion with the insulating member.
