Title: Gas sensor
Inventor: MATSUO YASUSHI
IPC: G01N27/409
Filed: 2000-08-31
Abstract: PROBLEM TO BE SOLVED: To make a detection element resistant to breakage even if an impact is exerted from the exterior in the case of a gas sensor used to detect a component to be detected in an exhaust gas. SOLUTION: An oxygen sensor 2 is equipped with a frame-fitted packing 10 on the end side of an insulation protecting body 104. The packing 10 comprises a packing body 12 and a wavelike frame 14. The packing body 12 is disposed between the protecting body 104 and a bushing 116. The frame 14 is disposed between the protecting body 104 and a projecting portion 106c of a detection element 106. In the oxygen sensor 2 thus structured, when an impact such as vibration is exerted from the exterior, the frame 14 of the packing 10 acts to absorb the impact (vibration) itself by being elastically deformed according to the impact. Therefore, an excessive force can be prevented from acting on the projecting portion 106c of the detection element 106 and thus the projecting portion 106c can be prevented from being broken.

IPC: H01L21/302
Filed: 2000-09-01
Abstract: PROBLEM TO BE SOLVED: To provide an etching method with which a resist selection ratio can be improved and an etching shape can be improved. SOLUTION: A treatment gas is introduced into an airtight treatment chamber 104 to form an SiO2 layer formed on a wafer W placed in the chamber.
