SOLUTION: This method includes a stage of etching a surface of a substrate (12) and forming channels (24, 26) and a stage of forming pedestals (54, 88) on the surface of the substrate. Anode sides (56, 89) demarcating fuel regions (68, 102) positioned to the channels (24, 26) are included in the pedestals. Electrolytes (46, 96) are arranged between anode sides (56, 89) and cathode sides (58, 90), and the fuel regions (68, 102) are capped by insulators (66, 98). One part of the substrate (12) is removed from the rear face, and the channels (24, 26) are exposed. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: A calorimetric hydrocarbon gas sensor (10) includes an electrochemical oxygen pump (18), a sensing element (12), and a multi-layered substrate (26) separating the sensing element (12) from the electrochemical oxygen pump (18). The multi-layered substrate (26) includes a plurality of overlying insulating layers, in which at least one intermediate layer (60) supports a first primary heater (58), and in which another intermediate layer (52) supports a temperature compensation heater (50a, 50b). The primary heater (58) functions to maintain the calorimetric hydrocarbon gas sensor (10) at a constant, elevated temperature, while the active compensation heater (50a) functions to maintain substantially equal temperatures as determined by the thermometers (46a, 46b) located on an intermediate layer (48) overlying the compensation heaters (50a, 50b). Control circuitry is integrated with power measurement circuitry to measure differences in the heat produced by the compensation heater (50a) and the thermometer (46a) in an active region (100), and the heat produced by the compensation heater (50b) and the thermometer (46b) in a reference region (102).
