Publication number: 20060180927Abstract: A contact structure includes contact members having leg portions which are deflected using internal stresses. Since the internal stress is used, the leg portions of the contact members are easily and reliably deflected even when the size of the contact members is reduced in accordance with the size reduction of an electronic component. Since the leg portions are elastically deformed and function as elastic contacts, a strain caused by a difference in coefficient of thermal expansion between the electronic component and the substrate can be absorbed by the contact members. In addition, since a plurality of elastic contacts are provided, even if there is a displacement between the electronic component and the substrate, an electrical connection between the electronic component and the substrate is reliably obtained.Type: ApplicationFiled: February 14, 2005Publication date: August 17, 2006Inventors: Daisuke Takai, Masami Aihara, Koichi Takahashi

Patent number: 5755938Abstract: An apparatus which allows a first film to be formed on a substrate by chemical vapor deposition (CVD) and a second film to be formed on the substrate by sputtering, wherein the processes are performed sequentially in the same deposition chamber without exposing the substrate to an oxidative atmosphere. The deposition chamber includes a first electrode and a second electrode located under the first electrode. A transfer mechanism loads a dummy target onto the first electrode and the substrate onto the second electrode prior to a CVD process. The dummy target is resistant to sputtering and thus does not contaminate the film deposited on the substrate during CVD. After CVD and prior to sputtering, the transfer mechanism unloads the dummy target and replaces it with a sputtering target for film formation by sputtering. Both the dummy target and sputtering target can be loaded and unloaded from a single pressurized storage chamber.Type: GrantFiled: November 9, 1995Date of Patent: May 26, 1998Assignee: Alps Electric Co., Ltd.Inventors: Hirofumi Fukui, Masanori Miyazaki, Masami Aihara, Chisato Iwasaki, Koichi Fukuda, Yasuhiko Kasama
