HIGH PRECISION HIGH RELIABILITY AND QUICK RESPONSE THERMOSENSITIVE CHIP AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to the technical field of thermosensitive chip products. Provided are a high precision high reliability and quick response thermosensitive chip and manufacturing method thereof, comprising a thermosensitive ceramic semiconductor substrate (1); glass protective layers (2) are alternately spray-coated and sintered on the two surfaces of the thermosensitive ceramic semiconductor substrate (1); and the two surfaces of the thermosensitive ceramic semiconductor substrate (1) having the glass protective layers (2) are printed with metal electrode layers (3). The thermosensitive chip achieves quick response, accurate control of resistance precision and has high precision; in addition, the glass protective layers thereof enable the thermosensitive chip to have high reliability.
