Humidity sensor |
| abstract |
The operation of relative humidity sensors made from cobalt oxide on a non-conductive ceramic substrate is improved by heating the sensor for a short period to a high temperature in a reducing atmosphere. This reduces the specific resistance of the device. With a lower resistivity, it is possible to reduce the size of the sensor to the point where it can be included along with a semiconductor device in standard hermetic packages. This makes possible the continuous, on-line monitoring of hermeticity for the lift of the circuit without the necessity of applying a load to the circuit. |
