Description

Quick-response and high-temperature-resistant film type temperature sensor and preparation method thereof
Technical Field
The invention relates to the technical field of temperature sensors, in particular to a fast-response and high-temperature-resistant film type temperature sensor and a preparation method thereof.
Background
The temperature sensor is mainly used for measuring temperature and has important application in the fields of industrial monitoring, agricultural production, scientific research and the like. As technology develops, more and more sensors are used for transient measurement, and the requirements on the size of the sensors are gradually increased. In recent years, the development of application technology and assembly technology of the platinum film thermal resistance temperature sensor is gradually mature. For example, in the process control, the safety and the reliability of the system work can be ensured by detecting the temperature in time. In the use of the new energy automobile, the platinum film temperature sensor can monitor the temperature of the energy battery of the automobile and the temperature of the new energy battery to prevent the device from being damaged due to overheating.
However, most of the platinum film resistance sensors used in China are foreign products imported and sold by dealers, and such technologies and products are monopolized by foreign manufacturers, and on the other hand, most of the existing platinum film resistance sensors have various defects, for example, in the Chinese patent 201880030405.6, a sensor for measuring gas parameters is disclosed, and the sensor structure is S-shaped, but the adopted materials have weak high temperature resistance. In addition, chinese patent 201610913940.9 discloses an antioxidant composite protective layer for a high-temperature thin film sensor and a preparation method thereof, wherein a long-time annealing mode is adopted, defects are generated on the surface of a thin film, so that the performance of the device is affected, and in view of the important role of platinum thin film thermal resistance in the civil field and the military field, the technical lag in this aspect of China is changed, and the method has a far-reaching strategic target.
The Temperature Coefficient of Resistance (TCR) is one of the key indexes for representing the performance of the platinum thin film thermal resistor, and the TCR value of most of the platinum thin film thermal resistors reported in China is still lower than 3.0 multiplied by 10 at room temperature -3 /. Degree.C.. In order to improve the temperature coefficient of resistance of the Pt thin film temperature sensor, one method is by high temperature annealing for a long time. It is found that the sensitivity of the device is reduced and the linearity is deteriorated due to the fact that the high temperature annealing for a long time reduces the defects of the thin film, but the buffer layer in the platinum resistance temperature sensor diffuses to the surface under the high temperature state for a long time, so that impurities on the surface of the thin film are increased. Therefore, at present, the TCR is improved by long-time high-temperature annealing at home, the performance is not obviously improved, the traditional buffer layer Ti is selected for relatively few researches on the buffer layer, and the selection is single, so that devices prepared at home mostly do not reach the international standard, the process time is too long, and the temperature rise and drop time is in hours. Another method is to select an insulating substrate with low thermal conductivity and high temperature resistance to prepare Pt, so that the TCR can be improved to a certain extent. Although the first method can improve the TCR to a certain extent, the annealing process is long, the temperature rise and reduction process is up to one day, the damage to the device is large, and the TCR of the prepared device is more than or equal to 3.0 multiplied by 10 -3 /. Degree.C.. The oxide single crystal substrate (e.g., alumina substrate, lanthanum aluminate substrate, etc.) used in the second method can effectively improve TCR, but the process cost is high, and the cost required for experimental design is excessive. The preparation processes of the two methods are relatively complex and the preparation cost is high, and a novel preparation process needs to be explored to improve the performance of the temperature sensor.
