Patent number: 7330043Abstract: A multi-bus semiconductor device and a method of its probing test perform the DC test for individual pads of a device while dealing with an adequate number of devices for simultaneous measurement based on the scheme of input/output pad number compressive test. The semiconductor device includes switch elements SW0-SW4 connected between input/output pads P0-P4 and a testing line L0 so that pads in an arbitrary combination, among the off-probe pads P1-P4 that are not made in contact with the tester probe Pr0, are selected for testing in correspondence to the combination of switch elements that are turned on. The input/output buffers of the pads under test are deactivated to block their internal current paths. The corresponding switch elements are turned on to connect the off-probe pads under test to the probe pad P0 that is made in contact with the tester probe Pr0, and the leak current of the probes is measured with the tester TS.Type: GrantFiled: March 15, 2005Date of Patent: February 12, 2008Assignee: Fujitsu LimitedInventors: Seiji Yamamoto, Hirosuke Koumyoji, Tohru Yasuda, Mikio Ishikawa, Isaya Sobue, Hajime Sato, Chiaki Furukawa, Akira Sugiura, Akihiro Iwase

Publication number: 20070111212Abstract: It is intended to provide a method of detecting a nucleic acid whereby a target nucleic acid can be accurately and quickly detected at an elevated detection sensitivity compared with the existing methods; and a gene detection kit with the use of this method. A sample containing cells is fixed to a support and nucleic acids are amplified on the support as such. Then, a nucleic acid thus amplified is detected. Since the nucleic acids are not detected from the sample in this method, a lowering in the detection sensitivity due to the nucleic acid loss in the step of extracting the nucleic acids can be prevented. Since the amplified nucleic acid is detected, furthermore, detection can be made even though the nucleic acid is contained only in a trace amount in the sample.Type: ApplicationFiled: February 8, 2005Publication date: May 17, 2007Applicant: Fuso Pharmaceutical Industries, Ltd.Inventors: Akio Matsuhisa, Seiji Yamamoto, Souji Eda, Shinji Yamasaki
