RESISTOR AND MANUFACTURING METHOD THEREOF, AND CIRCUIT

摘要

A resistor and manufacturing method thereof, and circuit, the resistor comprising: an insulating substrate (21); a resistor (22) disposed on the insulating substrate (21); a first electrode (23a) and a second electrode (23b) respectively connected to the resistor (22); a first conductive layer (24a) partially overlapping with the first electrode (23a); a second conductive layer (24b) partially overlapping with the second electrode (23b); a first barrier layer (25a) disposed between the first electrode (23a) and the first conductive layer (24a) to prevent external corrosive from contacting the first electrode (23a), and/or a second barrier layer (25b) disposed between the second electrode (23b) and the second conductive layer (24b) to prevent external corrosive from contacting the second electrode (23b). Adding a barrier layer between an electrode and a conductive layer prevents external corrosive from contacting the electrode, thus avoiding corrosion of the electrode due to the contact with the external corrosive.
