IPC: G01N27/41
Filed: 1993-11-12
Abstract: PURPOSE:To enhance mechanical strength and thermal efficiency by a structure wherein a sensor chip is bonded to a chip mounting member provided with a recess at a position matching the heater part of the sensor chip. CONSTITUTION:A sensor chip 1 is bonded onto a member 5 through Pt paste with the heater 2 side face opposing the chip mounting member 5 side. The member 5 is provided with a recess 6a at a position matching the heater 2 of the chip 1. Consequently, the gas in the recess 6a serves as a thermal insulating material to make difficult the absorption of heat generated from the heater, by the member 5 thus enhancing the thermal efficiency. Furthermore, even if the chip 1 is bent by the heat of the heater 2, the chip 1 does not touch the member 5. Since it is not required to form a large gap between the chip 1 and the member 5 using excessive Pt paste, the bonding strength is enhanced between the chip 1 and the member 5. Manufacture is also facilitated because the bonding of lead wire to the chip 1 is not required.
