Abstract

The invention includes a superalloy micro-heater, comprising a basement, an insulating layer arranged on the front side of the basement, a patterned heating resistance arranged on the insulating layer and a contact electrode arranged on the heating resistance, wherein, the heating resistance which is made of superalloy material has the advantages of corrosion resistance, high resistance, fast temperature rising and high temperature resistance and can greatly enhance the reliability and repeatability of the superalloy micro-heater.

Description

technical field [0001] The invention relates to a micro-heating apparatus, in particular to a superalloy micro-heater made of superalloy material. Background technique [0002] MEMS (micro-electro mechanical system, MEMS) uses semiconductor process technology to manufacture micron (micro-meter, μm) level mechanical structures, and can integrate various components to form a micro system. Its products cover optics, Electronics, electrical machinery, materials, physics, chemistry, biomedicine and other fields are typical cross-field integrated technology products. [0003] Micro-heaters made by micro-electro-mechanical technology have been widely used in recent years, such as micro-heaters applied to the nozzles of inkjet printers. When a current is applied through the resistors of the micro-heaters, the ink in the nozzles will be heated instantly. to boiling, and immediately pushed and sprayed out from the nozzle for printing; this kind of micro-heater for heating can also be...
