Patent number: 7901958Abstract: To permit electrical testing of a semiconductor integrated circuit device having test pads disposed at narrow pitches probes in a pyramid or trapezoidal pyramid form are formed from metal films formed by stacking a rhodium film and a nickel film successively. Via through-holes are formed in a polyimide film between interconnects and the metal films, and the interconnects are electrically connected to the metal films. A plane pattern of one of the metal films equipped with one probe and through-hole is obtained by turning a plane pattern of the other metal film equipped with the other probe and through-hole through a predetermined angle.Type: GrantFiled: August 10, 2010Date of Patent: March 8, 2011Assignee: Renesas Electronics CorporationInventors: Masayoshi Okamoto, Yoshiaki Hasegawa, Yasuhiro Motoyama, Hideyuki Matsumoto, Shingo Yorisaki, Akio Hasebe, Ryuji Shibata, Yasunori Narizuka, Akira Yabushita, Toshiyuki Majima

Patent number: 7888672Abstract: A device and method are provided for detecting stress migration properties of a semiconductor module mounted in a housing. A stress migration test (SMT) structure is formed in the semiconductor module. An integrated heating (IH) device is formed within or in direct proximity to the SMT structure. The SMT structure includes a first interconnect region in a first interconnect layer, a second interconnect region in a second interconnect layer, and a connecting region electrically connecting the interconnect regions through a first insulating layer. The IH device includes a heating interconnect region through which a heating current flows. The heating interconnect region is within or outside the first or second interconnect region or connecting region. When the heating current is applied, a measurement voltage is applied to the SMT structure, and a current through the SMT structure is measured to detect stress migration properties of the semiconductor module.Type: GrantFiled: May 19, 2005Date of Patent: February 15, 2011Assignee: Infineon Technologies AGInventors: Armin Fischer, Alexander von Glasow, Jochen von Hagen
