Patent number: 6204083Abstract: In order, to manufacture a high-performance infrared-emitting element having high-speed thermal response characteristics and a high infrared emissivity, a bridge (heat-generating) portion having a separation space is formed on a silicon element substrate. The bridge portion is formed to have a thickness of 5 &mgr;m or less by doping boron as an impurity by ion implantation with a concentration distribution peak value of 1.5×1019 atoms/cm3 or more, and performing annealing under predetermined conditions for activating the impurity layer. In the infrared-emitting element manufactured in this manner, even if the bridge portion is made thin to improve the thermal response characteristics, the infrared emissivity does not decrease because of a high impurity concentration, and a large temperature modulation width can be obtained. In doping boron as the impurity by ion implantation, the dose is preferably set to 3.0×1014 ions/cm2 or more.Type: GrantFiled: January 29, 1998Date of Patent: March 20, 2001Assignee: Anritsu CorporationInventors: Setsuo Kodato, Seishiro Ohya, Shiro Karasawa, Hiroyasu Yuasa, Kenji Akimoto

Patent number: 5251980Abstract: This invention provides a sensing system for measuring a specific value such as the thickness, thermal conductivity, or the like of a substance to be measured by utilizing a change in thermal resistance with a simple arrangement. A sensor has a temperature difference setting thin film (202) and a temperature difference detection thin film (203) formed on a substrate (201) made of a thermally poor conductor, converts a change in temperature difference of the substrate (201) before and after a substance (200) to be measured is thermally coupled to the substrate into a change in thermal resistance of the substrate (201), and outputs the change in thermal resistance as a temperature difference information signal for calculating a desired specific value of the substance to be measured.Type: GrantFiled: August 10, 1992Date of Patent: October 12, 1993Assignee: Anritsu CorporationInventors: Jun Hiraoka, Setsuo Kodato, Yoshinobu Naitoh

Patent number: 5102470Abstract: The electric resistor of this invention is comprised of a Si-Ge alloy thin film containing amorphous and microcrystal phases which serve as an electric resistance, thereby keeping the resistance value ratio substantially constant and uninfluenced by frequency changes which range from d.c. to 32 GHz. In addition, the power detector of this invention uses a thermocouple which is made by connecting the conductor film with the above-mentioned alloy thin film having great thermoelectric power. The thermocouple is provided with beam lead electrodes at cold junction areas to thereby produce large temperature differences between the hot and cold junctions, so that the thermocouple is provided with a sufficient thermal gradient to detect very low power with high accuracy.Type: GrantFiled: October 2, 1990Date of Patent: April 7, 1992Assignee: Anritsu CorporationInventors: Setsuo Kodato, Masao Nakamura
