Patent number: 8169054Abstract: The invention is directed to a semiconductor device having a via hole and a method of manufacturing the same that achieve both the prevention of a barrier layer insufficiently covering the via hole and the control of via resistance at the same time. A semiconductor substrate having a pad electrode on its front surface is prepared. The semiconductor substrate is etched from its back surface to its front surface to form a via hole exposing the pad electrode. A first barrier layer is then formed in the via hole by a sputtering method or a PVD method and reverse-sputtering (etching). By this reverse-sputtering, the barrier layer on the bottom of the via hole is removed to expose the pad electrode. A second barrier layer is then formed on the pad electrode exposed in the via hole. The via resistance is controlled by adjusting only the thickness of the second barrier layer.Type: GrantFiled: April 20, 2007Date of Patent: May 1, 2012Assignees: SANYO Semiconductor Co., Ltd., Semiconductor Components Industries, LLCInventor: Takahiro Oikawa

Publication number: 20100203721Abstract: An integrated circuit connection is describe that includes a first, securing member and a second, connection member. The first member, in an embodiment, is a spike that has a portion of its body fixed in a layer of an integrated circuit structure and extends outwardly from the integrated circuit structure. The second material is adapted to form a mechanical connection to a further electrical device. The second material (e.g., solder), is held by the first member to the integrated circuit structure. The first member increases the strength of the connection and assists in controlling the collapse of second member to form the mechanical connection to another circuit. The connection is formed by coating the integrated circuit structure with a patterned resist and etching the layer beneath the resist. A first member material (e.g., metal) is deposited. The resist is removed. The collapsible material is fixed to the first member.Type: ApplicationFiled: April 23, 2010Publication date: August 12, 2010Inventors: William M. Hiatt, Warren M. Farnworth
